I have mentored students at the undergraduate and graduate levels on independent projects and as members of my laboratory at my institution and across the United States. These students gain experience and expertise in designing research studies (e.g., survey development, participant recruitment and retention), data collection, and data management and analysis. Students are commonly invited to serve as co-authors on conference abstracts and peer reviewed publications. In recent years, I have had several students serve as lead author with papers accepted in journals such as Drug and Alcohol Dependence and conference abstracts accepted at the American Public Health Association and American Academy of Health Behavior amongst others. I am a firm believer that students serve an important role in research and that such settings are ideal for students to explore topics they are passionate about and I work with students to help them develop skills that will serve them as future public health professionals.


Dr. Tim Grigsby is an Assistant Professor in the Department of Social and Behavioral Health. He completed his PhD in Preventive Medicine (Health Behavior Research) from the University of Southern California in 2016. His primary research interests are on the health effects of childhood trauma, the conceptualization, measurement, screening, and prevention of substance misuse, and identifying sources of health disparities in Hispanic/Latinx communities. His secondary interests are in the dissemination of novel research and analytic methods in public health research. His work explores the role of family- and community-based trauma exposure as risk factors for substance use, misuse, and related health outcomes in minority populations. Specifically, his work has identified adverse childhood experiences and perceived discrimination as important risk-factors of substance use, violence, and adverse health outcomes in minority populations.
