Rachel Jonas, Ph.D.
Scientist
Human Factors
Los Angeles

Dr. Jonas has expertise in cognition, executive function, decision-making, risk-taking, reaction time, and the effects of inattention, distraction, and other experiences on human information processing and performance. She analyzes human factors issues related to a wide variety of contexts including automobile and pedestrian accidents; product warnings and safety information; eyewitness perception and memory; use of consumer products; and slips, trips, and falls.

Dr. Jonas earned her PhD in Neuroscience from UCLA, with a specialty in neuropsychiatric illness. Her research focused on the study of executive function (including attention, memory, impulsivity, and risky decision-making), and its relationship with the brain. Her graduate research involved a variety of techniques including behavioral, neuroimaging, and genetics to investigate both healthy individuals as well as those with genetic disorders. Throughout graduate school, Dr. Jonas was supported by awards from the National Institute of Mental Health, as well as multiple institutional fellowships and travel awards.
