Current lab members

Principal Investigator and Assistant Professor
Knight Alzheimer's Disease Research Center
Department of Neurology

Dr. Ganesh Babulal’s research interests lie in investigating the relationship between cognition and mental health and its impact on instrumental activities in populations with chronic neurological diseases, specifically, Alzheimer’s disease, dementia and stroke. Additionally, Dr. Babulal researches driving performance via road tests and driving behavior via naturalistic driving methodologies to understand changes and decline in healthy and clinical populations.

ResearchGate Profile

PhD Student/Engineer

Sayeh Bayat is a Ph.D. candidate in the Institute of Biomedical Engineering at the University of Toronto. She started working with the Roe lab in 2020. In the Roe lab, Sayeh is applying machine learning and geospatial techniques to explore whether GPS driving can be used to explain, influence, and/or predict preclinical Alzheimer’s disease. Sayeh’s research interests include spatial machine learning, healthy aging, driving, and mobility.

Senior Statistical Data Analyst

Dr. Jason Doherty is a Senior Statistical Data Analyst at the Roe Lab. He completed his MA, MScR, and PhD degrees in Psychology at The University of Edinburgh in Scotland, UK. His research to date has focused on comparing different theories of working memory, including work on an international “adversarial collaboration” in which senior researchers co-designed studies in order to compare the accuracy of their theories’ predictions. This project contributed to his interests in both identifying and developing robust statistical analysis plans for research and in Open Science.

Driving Evaluator

Brad Garland has been a part of the Roe lab since 2015 and  brings over 16 years of experience as the driving evaluator for our research studies. Mr. Garland has a BS in Education with an emphasis in Kinesiology, and a Driver Education and Safety endorsement. Brad has completed numerous post graduate hours of study in Educational Leadership and he is a co-owner along with his wife of My Tutor Learning Center and Driving School. Currently, My Tutor has 10 certified driving instructors on staff. Several thousand students and adults have received their driver’s license with the assistance of My Tutor’s certified instructors.  My Tutor services approximately 250 drivers annually.

Clinical Research Coordinator II

Ann Johnson joined Washington University School of Medicine in September 2000 and works for the Center for the Center for Clinical Studies. She currently coordinates multiple studies including Fitness to Drive, Driving Simulator Norming, Driving Simulator Stroke, Factors and Evolve: Traumatic Brain Injury in Service Members. She has worked with the Roe lab since 2012 and supports study coordination of the R01 grant.

Clinical Research Coordinator I

Samantha Murphy is a Clinical Research Coordinator for the Roe Lab. She completed her Bachelor’s degree in psychology and trauma studies certification at University of Missouri – St. Louis. She recently obtained her Master’s degree in clinical psychology from Southern Illinois University Edwardsville. Samantha has worked in various labs across the St. Louis area focusing her research on various neuropsychological topics. Her main research focuses have been on traumatic brain injury, family burden factors, and performance validity testing.

Principal Investigator and Associate Professor
Knight Alzheimer's Disease Research Center
Department of Neurology

Dr. Catherine Roe is currently an associate professor at the Knight Alzheimer’s Disease Research Center in the Department of Neurology. She completed her Bachelor’s in Psychology at Purdue and a Master’s and Ph.D at Southern Illinois University in Psychology. Her research interests are in the use of biomarkers for detection of preclinical and symptomatic Alzheimer’s disease (AD); in the prediction of AD-associated outcomes on an individual basis, and in associations between AD biomarkers and “non-cognitive” outcomes such as driving. Dr. Roe is also interested in how brain and cognitive reserve, mood, physical decline and neuropsychological factors impact both persons who are cognitively normal and persons with symptomatic AD. She is the PI of an NIH/NIA grant investigating preclinical AD and driving performance as well as other grants that examine naturalistic driving outcomes.

ResearchGate Profile

Dr. Monique Williams is a physician at BJC Medical Group, a member of the National Medical Association and is current President of Mound City Medical Forum. Additionally, she is a member of the NIA Health Disparities Resource Person Network, Gerontological Society of America Biological Sciences Executive Committee and Minority Issues in Gerontology Committee. Her research focuses on minority aging and health, Alzheimer’s disease, ethical issues in research and disparities across the lifespan. Dr. William’s bring her expertise on issues of health disparities, Alzheimer’s disease and inclusion of racial and ethnic minorities in aging research to our research.
