In short, just about everything you see around you every day and some things that you do not see such as pacemakers, groundwater, and artificial joints. Above all else, human health and safety are overriding concerns for the forensic engineer. The forensic scientist or engineer applies the tools and techniques of science and engineering to resolve questions relating to civil, criminal, and regulatory issues. Forensic scientists and engineers typically investigate accidents, product failures, environmental contamination, and criminal acts.
Incident investigations may involve bridge or building collapses, automobile collisions, air and rail accidents, explosions, shootings, and stabbings.
Practitioners of forensic engineering sciences may be involved in helping to apprehend and convict criminals on the one hand or exonerating and protecting the innocent on the other. They may also provide support in lawsuits based on claims that negligent acts caused personal injury. Other cases may use forensic engineers to correctly assign blame for environmental harm, to evaluate claims that product flaws resulted in injury to the user of the product, and to show whether patent rights have been infringed.
Many requests for forensic engineering services involve criminal and civil suits in which the forensic scientist or engineer will be asked to render expert opinions regarding the results of examinations. These opinions may receive further scrutiny in a deposition or during a trial. In most legal disputes involving science and engineering issues, each party will have their own experts who will evaluate the credibility of the proffered forensic analysis. Before becoming a forensic scientist or engineer, you must first become a scientist or an engineer. An individual specializing in any one of these disciplines should have a broad-based education that will provide a good understanding of all other disciplines.
The forensic engineer or scientist should become an expert at one or more component disciplines. Examples might involve becoming an expert in environmental data collection and analysis including use of the mass spectrometer and gas chromatograph. In still another example, the investigator of an accident involving military munitions should have become expert in non-destructive, non-invasive evaluation using advanced imaging techniques such as gamma radiography, ultrasound, and MRI scans in order to ascertain what went wrong. Depending on the field chosen, an advanced degree, MS or PhD, may be recommended.
Work experience in the chosen field is a plus. Other essential capabilities include writing and speaking skills. Knowledge and understanding of legal procedures and standards of proof are often important. Active participation in professional organizations and continuing education are highly recommended. The forensic engineer or scientist must be highly competent, ethical, credible, and should have extensive professional experience in the subject matter under consideration.
Inspecting a product for design defect is just one of the many applications called upon by the forensic engineer. Job opportunities for forensic engineering scientists track those for other types of forensic practitioners—crime labs at the federal, state, and local levels; law enforcement agencies; research laboratories; insurance companies, and small or large corporations. An opportunity for private consulting practice exists for many forensic engineering scientists once they are well into their professional lives. Far more than in any other sections of the American Academy of Forensic Sciences, Members and Fellows in the Engineering Sciences Section operate their own consulting firms that range in size from a single practitioner to multiple individual experts.
The primary clients for these small consulting firms are attorneys with civil and criminal practices, corporations, states, municipalities, as well as prosecutors at all levels of government. Some engineers and scientists are choosing to pursue forensic engineering sciences as a first career, which adds a younger contingent to this growing community. Nor is there an end in sight to the number of present or future specialties that may become forensic.
The examples are many. The General Section was founded in and is the third largest section in the Academy. It is the home of established areas of forensic science not fitting into the more narrow definitions or membership requirements of the other sections, newly emerging forensic scientific specialties, or those forensic specialists whose numbers are not sufficient to support a separate section. The goal of every section of the Academy is to promote professionalism, integrity, competency, education, foster research, improve practice, and encourage collaboration.
Membership in the General Section provides opportunities for professional development, personal contacts, and recognition of achievements. Additionally, members can advance their scientific proficiencies by learning from and consulting with scientists with broader experiences and similar interests. Members of the General Section represent forensic specialties in the areas of laboratory investigation, field investigation, clinical work, education and research, and other emerging forensic science disciplines.
New areas of forensic study result from a combination of adaptation, unique problem solving, and advances in natural and social sciences. Our latest accepted discipline is Forensic veterinary sciences, concerned with the health and welfare of animals through the recovery, identification, and examination of material evidence of inhumane destruction, treatment, abuse, neglect, or illicit trade in animals or animal parts for legal purposes. Veterinary technologists and technicians perform medical tests under the supervision of a licensed veterinarian to treat or to help veterinarians diagnose the illnesses and injuries of animals.
One of our larger subgroups includes forensic nurses specializing in areas such as sexual assault examination, clinical forensic medicine, and death investigation. These specially trained nurses contribute to any manner of investigations involving human injury or illness. Work experience requirements vary with educational levels and specific field of interest. Almost all agencies that support forensic science personnel provide opportunities for continuing in-service training and many offer additional advanced training.
Student mentoring is an especially important component of education for disciplines such as bloodstain interpretation, medicolegal death investigations, and forensic artistry, for which specific college degree programs have yet to be developed. Forensic crime scene investigators assess a mass grave site. Many of the forensic scientists within the General Section work for universities, police agencies state, city, and local agencies , federal agencies such as DEA, ATF, and FBI , and criminal investigation arms of the military forces and their support laboratories.
Private companies and independent forensic specialists are consultants to either the prosecution or defense.
Income is dependent on specialty and geographical area and is generally increasing for the well-trained forensic scientist. Career advancements are available in many agencies and are dependent on the discipline. As crime continues to evolve with technology and society, forensic scientists will be challenged to respond by adapting established technologies and, where necessary, developing new ones. These emerging forensic science disciplines will continue to be of vital importance to the courts and society in general.
Forensic Science: Current Issues, Future Directions
Forensic radiologist interpreting x-rays for case preparation. Many of the forensic sciences — such as fingerprint analysis and document examination — originally developed from the need for lawyers to explain the significance of physical evidence to a case, often to identify a perpetrator of a crime.
All forensic science is evidence used by lawyers in presenting and explaining their cases in court. Rapid advances in scientific knowledge during the last century resulted in scrutiny by attorneys and courts of the validity of then-current scientific analytical techniques. A forensic scientist will frequently be asked to provide testimony as an expert witness who has conducted a scientific analysis of the evidence in a legal proceeding. Consequently, forensic scientists must be aware of the process involved in being qualified as an expert and the evidence standards that will be applied to the scientific analysis performed by the forensic scientist.
New Book Explores the Future of Forensic Sciences
Expertise comes from education, training, or experience and can be based on the scientific method or on specialized training. Counsel on both sides of a matter being tried in court, as well as the judge presiding over the trial, are lawyers. They are the main players in the drama of the courtroom. A lawyer who uses expert testimony in a criminal, civil, or other legal proceeding must know the laws that govern the admissibility of scientific evidence and be able to apply these laws when submitting or challenging scientific evidence in depositions and court proceedings.
The judge, also, must understand the issues concerning the validity and admissibility of scientific evidence and must ensure the legality of the entire process. Much depends on the knowledge, training, education, and experience of the forensic scientist whom a lawyer seeks to qualify as an expert witness since an expert witness, and only an expert witness, is permitted to testify to an opinion based on analyses performed by the expert. Although each deposition, hearing, or court appearance is a unique experience, forensic scientists testifying in a legal proceeding may reasonably expect questioning to cover at least a few key areas before the scientist is qualified as an expert by the judge.
Education in the field of specialized knowledge in which the witness claims to be proficient will be most relevant and may cover any and all formal education the witness has — or has not — completed. Cross-examination by opposing counsel is typically more challenging. There are limits to all scientific disciplines. Experts well-versed in their discipline should be aware of those limits and be able to testify with ease about what can — and cannot — be known regarding a given piece of evidence. Members of the Jurisprudence Section must possess a law degree, have passed a bar examination, and be licensed members in good standing of the bar in one or more states.
Full-time law school students are eligible to join the section as student affiliates. Continuing education is essential for lawyers to stay current as forensic science advances and legal standards adapt to these advances. Judges are lawyers who have been appointed or elected to the bench. Lawyers working with forensic science issues may be employed in a variety of broad fields or specialties and by a broad range of employers and organizations. Some are employed by large private companies; still others teach in colleges and universities. Hours of work and income are dependent on geographical area; place of employment; experience; status and reputation; and, type of practice.
Odontology Natural and synthetic crowns and bridges dentition. Forensic dentistry odontology is a vital branch of forensic science that involves the application of dental knowledge, primarily for the identification of human remains. Forensic dentists deal with a range of medicolegal problems, but the most common issue addressed is identification of human remains. Often no fingerprints are on file or are destroyed by decomposition, fragmentation, or by fire as occurred in and in most air disasters.
Natural disasters such as tsunamis, hurricanes, and volcanoes can involve an enormous number of deceased. Buried bodies may even need to be re-identified if caskets are washed out of the ground by flooding or avalanche. The identification of an unknown or confirmation of an identity is performed at the request of the coroner or medical examiner.
Fragments of a jaw or a single tooth can be sufficient to make an identification providing antemortem pre-death dental X-rays are available for comparison. A postmortem after-death oral examination includes intraoral and extra oral photographs, dental X-rays, and dental charting. In the absence of a missing person match, the dental characteristics of an individual can give law enforcement clues to identity. Postmortem dental data can be rapidly compared to antemortem data using a database such as WinID www.
Department of Justice. Another important area of forensic dentistry is bitemark analysis. Bitemarks can occur during a variety of human activity including assault, domestic violence, rape, elder abuse, self-defense, sports, accidents, infanticide, or other homicide. The American Board of Forensic Odontology www. New odontologists would be wise to work with experienced mentors certified by ABFO when doing their first few cases. DNA collection at autopsy or in the living is part of the bitemark protocol.

The American Society of Forensic Odontology www.
It is the entry-level organization, and anyone with an interest in forensic odontology can apply for membership. Other institutions in Europe and Australia also have programs available. These courses are highly recommended because they specifically concentrate on forensic dental education. Reimbursement is usually on a fee-for-service or contractual basis. Once a commitment is made to enter this field, the forensic dentist needs to be current in the most accurate methods available, be aware of ethical values and conflicts, and possess the dedication to render an impartial opinion in a timely and professional manner.
The diverse fields of forensic biology and the life sciences and forensic pathology play important roles in forensic science. This section of the AAFS comprises a diverse group of members, all with important roles in forensic investigations. Forensic pathology is the practice of medicine concerning injury analysis and performance of autopsies to determine cause and manner of death.
Pathology is a medical specialty—the study of disease. Pathologists study disease by performing a type of surgery called an autopsy. Tissues and organs removed during an autopsy are examined for evidence of disease and injury and may also be examined under the microscope. Analysis of fluids taken from the body, such as blood or urine, also provides information about disease to the pathologist. Forensic pathology is the application of the principles of pathology, and of medicine in general, to the legal needs of society.
They are also involved in the investigation of the circumstances surrounding the death. Knowing about these circumstances allows them to determine the manner of death—natural, accident, suicide, homicide, or undetermined. Although there is much emphasis on violent deaths, forensic pathologists and biologists also investigate sudden deaths of seemingly healthy individuals, deaths of people who have never seen a doctor, deaths occurring in police custody, suspicious or unusual deaths, deaths resulting from surgical or diagnostic procedures, or some deaths that occur in public institutions.
The law of the specific jurisdiction where the death occurs determines which deaths must be reported to the medical examiner often a forensic pathologist or, in some states, the coroner. Then the medical examiner, or coroner, is responsible for deciding if an autopsy is necessary to determine the cause and manner of death. A forensic biologist will assist these individuals, along with other investigators, as well as provide insight into the postmortem interval time elapsed since death and the location of bodies that have yet to be discovered.
Forensic biology is the application of the life sciences to legal and regulatory investigations. Forensic biology comprises all of the life sciences including, but not limited to, entomology, genetics, microbiology, ecology, and botany. A forensic biologist studies organisms or cells of organisms that are associated with criminal activity. Many organisms, including insects, bacteria, plants, and fungi can be used as evidence because they indicate the time at which an event took place, or they associate a particular person with an object or a location. Genetics are regularly used to confirm the identity of these organisms.
In many instances, forensic practitioners of these disciplines have a broad application for their discipline with a wide range of job opportunities e. The body is usually photographed and diagrammed with a detailed written report describing any injuries or disease process. The autopsy usually includes microscopic examination of the tissues of the body. X-rays may also be taken to look for bullets, broken bones, or other abnormalities.
The forensic pathologist works with other branches of the forensic sciences. These are sent to the forensic laboratory for examination by a criminalist—a scientist trained in the examination of physical evidence. The forensic pathologist also collects specimens, such as blood, urine, bile, stomach contents, and body tissues, for toxicology analysis.
The toxicologist looks for the presence of alcohol, drugs, and other chemicals or poisons in these specimens. If bullets, shotgun pellets, or wadding are recovered at autopsy, they are also sent to the forensic laboratory for examination. A firearms examiner analyzes these specimens and is often able to match them to a specific weapon. Forensic pathologists also work to identify unknown deceased persons by way of medical information, dental records, and other unique features of an individual. If the body has deteriorated to a skeleton, forensic pathology may determine the race or sex of the individual.
Forensic pathologists are often assisted by forensic odontologists dentists and physical anthropologists with the assessment of cases and the identification of deceased individuals. Examination of the deceased may reveal whether the person received injuries, also called trauma, both prior to antemortem and after postmortem death, as well as changes to the body that occurred as a result of decomposition after death.
Each type of injury e. Forensic pathologists are trained to recognize these patterns and thereby determine the cause and manner of death. Injury patterns are especially important in cases of child abuse and elder abuse. Autopsy findings must correlate with the other known physical and circumstantial evidence.
Sometimes, examination of the body may reveal that the victim died in a distant location and in a very different position from the situation in which the body was actually found. The forensic pathologist must maintain accurate and unbiased written and photographic records. This work may lead to the conviction of the guilty or the exoneration of the innocent.
Another aspect of forensic pathology is the role this science plays in the areas of public health and disease and injury prevention. The forensic pathologist may be the first to recognize an epidemic disease or document a faulty product design that resulted in injury and death. Genetic disorders may be identified at autopsy and reported to those surviving family members who may be affected. An emerging role of the forensic pathologist is that of clinical forensic pathology.
Patterns of injury are not visible only when persons are deceased—they can also be recognized in living patients in emergency rooms and clinics. This is especially critical in cases of child and elder abuse. The interpretation of these injuries is invaluable to police or other law enforcement officials in a criminal investigation. The forensic pathologist plays an important role in communication with bereaved families as well as other physicians, attorneys, and law enforcement officers in an effort to provide all those who have need with proper, accurate, and timely information.
Assistance to those who are left to deal with the loss and trauma surrounding the death of a human being is the reason for the work of the forensic pathologist.

However, because forensic biology is quite diverse, the role s of such an individual will be field-specific. Forensic biologists typically collect evidence concerning perimortem at the time of death activity, postmortem interval, and location of relevant evidence. In other investigations, a forensic biologist will receive evidence collected by an investigator. A forensic biologist will analyze samples they collect or that are provided, as well as photographs and case notes prepared by other investigators including the forensic pathologist.
A forensic biologist typically serves as a forensic specialist and will be called to contribute to medicolegal death investigations when their specialty is needed. For example, a forensic entomologist will contribute expertise to a death investigation to determine the time of colonization of human remains, which in many cases represents a minimum postmortem interval time since death.
Forensic entomologists may also provide information from examining insects to help determine when trauma occurred before or after death , if the remains had been moved from one location to another, identification of the individual from DNA collected , and toxicology. One emerging field of forensic biology is forensic microbiology.
Forensic Science: Current Issues, Future Directions by Douglas H. Ubelaker
Forensic microbiologists use bacteria, Archaea, and microbial eukaryotes to provide insight into several aspects of medicolegal death investigation including cause-of-death, manner-of-death, identification, and postmortem interval. This is a rapidly developing field that will likely provide several new discoveries over the next few years.
Forensic biology also includes the work of botanists—those plant specialists who provide expertise in interpreting stomach contents or locating clandestine graves. Forensic veterinary sciences is also an emerging field where veterinarians are called on to examine animals for documentation of trauma.
All forensic pathologists are medical doctors with an MD or DO degree. Therefore, the training requirements involve many years of studious effort. After four years of college and four years of medical school, an apprenticeship in pathology, known as a residency, is required. Forensic pathology is a subspecialty of pathology, so an additional one-year fellowship in forensic pathology is required.
Medical board certification in anatomic pathology and forensic pathology is acquired from The American Board of Pathology. Most of these scientists conduct research in a field of biology that can be applied to a forensic investigation. Many forensic biologists also work in a non-criminal area of life science such as agriculture or conservation. Certification can be acquired in some areas of forensic biology, such as certification in forensic entomology from the American Board of Forensic Entomology.
Veterinarians must complete a four-year graduate degree program, pass a national board exam, and hold a valid license to practice veterinary medicine within a given locality. Veterinarians focusing on pathology can undertake a residency program in pathology to further their specialization. Forensic pathologists are usually employed by city, county, or state medical examiner or coroner offices; hospitals; universities; and federal government agencies, such as the Centers for Disease Control CDC and the Armed Forces Medical Examiner.
Forensic pathologists may also work for private medical groups as consultants by performing forensic autopsies. Forensic biologists work in crime laboratories, but are more often associated with universities, museums, or other government agencies. These scientists typically serve as consultants to medical examiners and coroners while conducting research in an area of forensic biology. All the forensic specialties play an important role as expert witnesses for attorneys in criminal both prosecution and defense and civil cases.
In criminal law, the focus is on issues such as competence e. Civil cases typically require assessment of issues such as involuntary psychiatric commitment, the right to refuse treatment, competence to make medical decisions, and appropriate disability compensation if any.

Family and domestic relations cases may include juvenile delinquency, child custody, parental fitness, domestic abuse, adoption, and foster care evaluations. Forensic psychiatrists and psychologists often spend a significant amount of time working with attorneys and judges and are trained in giving effective expert testimony.
In organizing the components of a forensic psychiatry assessment, a four-step series of questions is often used:. An attorney or other retaining party may ask the expert to opine on several psychiatric-legal issues in a single case or referral and each issue should be addressed separately.
For example, a criminal defendant might be evaluated to determine the following:. Some of these questions require retrospective analysis e. The data collected and utilized to formulate opinions obviously will differ depending on the issue the psychiatrist or psychologist is asked to address. Psychiatrists are medical doctors who generally have completed twelve years of education and training, including undergraduate, medical school, and residency training in general psychiatry.
Forensic psychiatrists also may have additional training and experience in subspecialties relevant to the evaluations they conduct e. Others pursue a career of independent study and on-the-job training. The American Board of Psychiatry and Neurology certifies competence in psychiatrists who have completed an accredited fellowship and passed an examination. The Accreditation Council on Fellowships in Forensic Psychiatry and the Accreditation Council of Graduate Medical Education certify the quality of post-residency, subspecialty fellowship training programs.
Some psychologists complete post-doctoral fellowship training in forensic psychology. Other psychologists study independently and obtain on-the-job-training in forensic psychology. These specialists then apply to the American Board of Professional Practice in Psychology for certification in the specialty of forensic psychology through an examination process. Forensic psychiatrists and psychologists may be employed in private practice; by private hospitals; by state hospitals; by city, county, or state governments; or by the federal government. For example, they may work in a state prison or a state hospital setting.
Alternatively, they may have their own private practice and serve as consultants to a broad range of organizations that interface with psychiatry, the behavioral sciences, and the law. Questioned document examination, also referred to as forensic document examination, is the branch of forensic science best known for the determination of authorship of signatures and handwriting but, in fact, involves much more comprehensive analyses of writing instruments, writing mediums, and office machine products.
A document examiner will accomplish the analyses of the above-referenced forms of examination requests by utilizing state-of-the-art equipment in conjunction with standard methodologies. Most document examiners limit their examinations to nondestructive methodologies. In instances in which destructive tests for purposes of ink analysis or paper analysis may yield beneficial results, document examiners will refer that specific testing to an appropriate ink or paper chemist for destructive analysis.

Forensic document examiners are employed in both the public and the private sector. Private examiners can be found in many major cities in the United States. Large police agencies, along with most state and federal law enforcement agencies often employ document examiners in their crime laboratories.
Lists of qualified document examiners are provided through membership lists of the certification organization the American Board of Forensic Document Examiners www. There are also several regional organizations with members who are most willing to assist in your quest into the fascinating realm of questioned document examination. Toxicology is the study of adverse effects of drugs and chemicals on biological systems. Forensic toxicology involves the application of toxicology for the purposes of the law, or in a medicolegal context. A forensic toxicologist answers questions such as:. Answering questions like these often requires forensic toxicologists to work with, and share information with, law enforcement, forensic pathologists, death investigators, crime scene investigators, clinicians, other forensic scientists, and legal professionals.
The field of forensic toxicology involves three main sub-disciplines: postmortem forensic toxicology, human performance toxicology, and forensic drug testing. These specialized fields offer a variety of exciting career paths. In postmortem forensic toxicology, forensic toxicologists work with pathologists, medical examiners, and coroners to help establish the role of alcohol, drugs, and poisons in the causation of a death. The forensic toxicology laboratory identifies and quantifies the presence of drugs and chemicals in biological fluids and tissues that are taken from the body during the autopsy.
A wide array of specimens may be encountered in postmortem toxicology investigations including blood, urine, vitreous fluid from the eye, liver, brain, and other tissues, as well as hair and nails. Once the testing is complete, a forensic toxicologist then interprets these findings.
This information helps a forensic pathologist determine the cause and manner of death.
