Principal Investigators


Ganesh Babulal, PhD, OTD, MSCI, MOT, OTR/L

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, dementian 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.

He is an Associate Professor in the Department of Neurology and affiliate faculty in the Knight Alzheimer’s Disease Research Center at Washington University School of Medicine. He works with the DRIVES team on several studies funded by the NIH/NIA and other organizations.

Darrell Hudson, PhD

Dr. Darrell Hudson’s research focuses on racial/ethnic health disparities and the role of social determinants of health, particularly how socioeconomic position and social context affect health and health disparities. He is currently investigating why data show that African Americans — despite bearing a disproportionate burden of physical health disparities and greater exposure to stress — have lower rates of depression compared to white Americans.

He has examined perceptions of depression and mental health care among African Americans and investigated comorbid depression and Type 2 diabetes in various settings. He also co-directs the Collaboration on Race, Inequality, and Social Mobility in America within the Brown School’s Center for Social Development. Hudson holds a joint appointment with the Washington University Department of Psychiatry and is a faculty scholar with the Institute for Public Health.

He teaches the courses “Social Epidemiology,” “Health Behavior and Health Promotion,” as well as “Transdisciplinary Problem Solving: Popular Culture and Public Health.” Prior to his faculty appointment, Hudson completed a postdoctoral fellowship with the Kellogg Health Scholars Program at the University of California at San Francisco/Berkeley.

Dr. Hill previously served as the Association’s vice president, Scientific Engagement. Prior to joining the Association, he served as director, Office of Special Populations at the National Institutes on Aging (NIA). Throughout Dr. Hill’s six years in this role, he led the development of the NIA Health Disparities Research Framework, which stimulates studies focused on health disparities related to aging.

Dr. Beau M. Ances, MD, PhD

Clinically, Dr. Ances sees patients in the inpatient and outpatient settings with a variety of neurodegenerative diseases (including AD, DS-AD, ADAD, HAND, CJD, AIME, and neurological complications from COVID19).

Dr. Jean-Francois Trani, PhD, MA

Dr. Jean-Francois Trani investigates the intersection of mental health, disability, vulnerability and poverty with a focus on conducting field research that informs policy and service design for individuals living in conflict-affected fragile states and low-income countries. He is a member of the Prevention Research Center and the Social System Design Lab at the Brown School.

Using the Capability Approach of Amartya Sen, Trani hypothesizes that lack of opportunity — or poor conversion factors — is linked to stigma of disability and other discriminated groups, which results in social exclusion and creates mental distress. He argues that efforts to improve the well-being of persons with disabilities and other vulnerable groups must address the overlooked issue of stigma.

Trani’s research has contributed to policy papers of the Ministry of Education and the Ministry of Public Health in Afghanistan. He is an editor of ALTER, the European Journal of Disability Research and the Revue Tiers Monde. He is also a coordinator of the Health and Disability group at the Human Development and Capability Association.

Trani’s teaching is linked to his professional experience in global health and international development, and he involves master and doctoral students in all phases of his research projects.
