Martha E Brown, MD


A forensic medical expert is a physician who has the clinical experience and academic training to form an informed, objective medical opinion to a reasonable degree of medical certainty. The forensic psychiatrist evaluates the mental and emotional factors that are relevant to a particular legal contest. This process occurs through clinical interviews, record analysis and psychological and medical testing to formulate an independent and objective opinion. An expert opinion is then thoroughly and effectively communicated by written report, deposition and, if necessary, courtroom testimony. Our faculty and complementary experts possess an impressive range and depth of experience and expertise in forensic psychiatry and supporting disciplines.

We believe the primary requirement of an expert witness is to be a skilled and knowledgeable clinician with the ability to provide objective and insightful assessment and then to work collaboratively with either the plaintiff or defendant’s counsel.

Additionally, to be a member of the UF Forensic Psychiatry Services it is required for an expert witness to be a teacher. Our experts have demonstrated their excellence in persuasively translating their knowledge in an understandable and impartial fashion to court professionals, medical trainees and lay persons alike.

An expert witness must educate attorneys with regard to the relevant behavioral and clinical aspects in the case. If that case proceeds to trial, our experts will conscientiously inform the court and jury with regard to their opinions, as well as the medical foundations for these opinions.

Inherent in our participation is a genuine interest in the field and a seasoned understanding of the role of an expert including the desire to exceed expectations in documentation, thorough and timely reporting and adept provision of testimony.

Forensic Addiction Medicine

A medical expert in addiction medicine is a physician who has the clinical experience, academic training and certification to form an expert, objective medical opinion in cases involving alcohol and drugs or other addictive behaviors (i.e. gambling, sex, etc.). The applications of forensic addictionology are widespread in both the civil and criminal proceedings.

A forensic addictionologist integrates his clinical experience with his knowledge of medicine, mental health and the neurosciences to answer questions related to how a particular addiction can influence behavior. Our expert gathers and analyzes extensive, relevant data to formulate an opinion. This opinion is objectively presented by written report, deposition and courtroom testimony, as necessary.

Forensic Pain Medicine

An expert in pain medicine is a physician who has the clinical experience, academic training and certification to form an expert opinion in cases involving the evaluation and management of acute and chronic pain as it relates to both criminal and civil proceedings.

A forensic pain medicine physician integrates his knowledge of pain and pharmacology to answer questions related to how chronic pain and its treatment can influence cognition and behavior. Our experts review medical records, depositions and other documents; perform evaluations of the plaintiff; and consult with the attorneys with respect to the merits and vulnerabilities of the case from a medicolegal perspective. In some cases, the forensic expert may assist by reviewing relevant scientific literature for the attorneys or offer advice with respect to other forensic experts who might be recruited.

Forensic Psychology & Neuropsychology

Litigating cases involving psychological or neuropsychological dysfunction requires expert consultation. The evaluation of emotional, behavioral and cognitive status is paramount to successfully representing your client.

Our experts provide scientifically-informed, objective psychological and neuropsychological evaluations in cases involving intellectual disability or acquired psychological/neuropsychological impairment due to traumatic brain injury, stroke, anoxic encephalopathy or neurotoxic exposure.

Civil cases are frequently referred by plaintiff or defense counsel practicing in the areas of personal injury, medical malpractice, mass tort, product liability or premises liability litigation.

Our forensic psychologists/neuropsychologists are also retained to evaluate individuals involved with the federal and state criminal courts on matters such as mental competency, criminal responsibility/diminished capacity, mitigating factors.
