Dr. Ketcherside is a cognitive neuroscientist with expertise in the underlying factors that drive decision-making. Through her training, research, and experience, Dr. Ketcherside has expertise in emotion, reward, and decision making, as well as visual perception, attention, driver behavior, and the effects of alcohol and other drugs on human performance. She applies her knowledge to help clients understand such issues as consumer purchase decisions, consumer product use, and effectiveness of safety- and product-related information. Her expertise is also leveraged across a variety of failure analysis and safety-related contexts, including slip, trip, and falls, motor vehicle accidents, and incidents involving consumer products and medical devices.

Dr. Ketcherside’s research and consulting experience has included a wide variety of methodologies to understand human behavior. These include neuroimaging, statistical modeling, genetics and biomarker assessment, and neuropsychological testing. She also has experience in pre-clinical drug discovery and testing, as well as with clinical trial research. Dr. Ketcherside is skilled in study design, execution, and advanced analysis of data from human participant research, including experimental, observational, survey, interview, and focus group studies.

Prior to joining Exponent, Dr. Ketcherside earned a BA in Biology at Austin College. She worked at UT Southwestern Medical Center, where her work contributed to pre-clinical research, before obtaining her PhD in Cognitive Neuroscience at the University of Texas at Dallas. Her graduate research investigated addiction, how the brain responds to reward-related stimuli, and the influence of drugs and emotions on cognition. She also completed a postdoctoral fellowship at the University of Pennsylvania, where she evaluated the efficacy of a medication for smoking cessation.
