Dr A. E. Du Beau, PhD, MS, BS, is a neuroscientist with special expertise in forensics. Neuroscience investigates all aspects of the brain’s functionality, inclusive of neurochemical and anatomical processes that underlie behavior, perception, cognition, mentation and consciousness. Dr Du Beau’s neuroscientific expertise includes altered states of consciousness and sleep, alcohol blackout, psychoactive drugs, traumatic brain injury, memory processes, intentionality, violence and criminality. For contrast, psychologists and psychiatrists are clinicians who are principally focused on the mental state of any given patient, diagnostics and establishing a therapeutic relationship. Conversely, neuroscience uses an analytical approach to understanding how the brain works. Dr Du Beau’s doctoral research at the prestigious University of Glasgow (Scotland, United Kingdom) investigated the neurochemical properties of neural systems using an array of sophisticated laboratory, surgica...

As a 24-year federal agent (still active) and licensed clinical psychologist, my areas of expertise include science-based investigative interviewing, coerced or false confessions, the dynamics of interpersonal crimes and police/investigative practices.

Human Factors, Pharmacology - brain, memory, stress, post-traumatic stress disorder, PTSD, memory failure, forgotten baby syndrome, amnesia, trauma, heatstroke, automobile-related fatality, cognition, traumatic brain injury, negligence, decision-making

I am a professor in the Department of Psychology, Cognitive, Neural and Social Division, at the University of South Florida. I have been studying the brain and memory for over 40 years, and I have served as an expert witness on memory-related cases for the past 16 years. In one area of expertise, I have studied how parents and caretakers, without evidence of abuse or neglect of children, unintentionally and unknowingly, forget children in cars. Under conditions in which the ambient temperature is warm enough and the car is exposed to direct sunlight, heat builds within the car and the child may die or become brain damaged as a result of heatstroke. I have testified as a memory expert in cases in which these parents and caretakers have been charged with civil and criminal crimes, including manslaughter. In a related area of expertise, I recently retired as a career scientist in the Department of Veterans Affairs, with 30 years of research on post-traumatic stress disorder (PTSD). I ...

Psychology, Forensic Psychology - Memory, Eyewitness Testimony, Cognitive Neuroscience, Neuroscience, Learning, Decision Making, Habits, Behavioral Science, Episodic Memory, False Memory, Memory Reconstruction, Memory Bias, Misinformation Effect, Memory Confidence, Source Misattribution, Jury Misconceptions

Dr. Braun is a Cognitive Neuroscientist specializing in memory, learning, and decision making. She provides expert witness testimony on the complexities of eyewitness testimony, including issues related to false memories, the misattribution effect, memory reconstruction, and the inherent susceptibility of normal memory recall to error. Dr. Braun earned her Ph.D. in Psychology from Columbia University and has published in leading scientific journals such as Nature Neuroscience and Nature Communications. Her dissertation focused on the retroactive modulation of memory, exploring how memories are altered by subsequent events. Extensive research has demonstrated that when an episode is recalled, the memory is not replayed perfectly like a video recording. Instead, the brain reconstructs the memory each time it is remembered, utilizing associative processes. This reconstruction renders memory, and consequently eyewitness testimony, vulnerable to errors and biases. Despite compelling sc...
