Greg EgertonGreg Photo
5th year PhD student
email: gegerton@buffalo.edu

B.S. Psychology and Second major in Anthropology, University of North Carolina at Chapel Hill

Greg is a fifth year doctoral student in the clinical psychology program. Greg studied psychology through work at the Center for Developmental Science, Department of Psychology, and Department of Psychiatry at UNC Chapel Hill. His laboratory work involved several areas of study, including developmental pathways to substance use and addiction, the assessment of pediatric and adult bipolar disorder, and the development of gratitude in children.

Greg studies the development of alcohol and substance use disorders and how this relates to co-occurring disorders, such as post traumatic stress disorder (PTSD). He has a particular interest in how different reinforcement processes may explain the relationship between problematic alcohol use and PTSD, as well as normative changes in alcohol use across development. In Greg’s free time he enjoys binge-watching TV shows, listening to music, drawing, and playing fantasy football.

Tiffany Jenzer

5th year PhD student
email: tjenzer@buffalo.edu

B.S. from the University of Toronto

Tiffany is a third year doctoral student. As an undergraduate, Tiffany volunteered in social psychology labs, where she gained an understanding of the experimental process. Soon after, Tiffany developed an interest in clinical psychology and worked as a lab manager at Ryerson University, where she assisted with various projects related to the development and treatment of Posttraumatic Stress Disorder (PTSD).

Tiffany’s current research interests focus on the etiological and causal relationships between PTSD and substance abuse, as well as possible treatment interventions for individuals living with this co-morbidity. In her spare time, she enjoys jogging, watching movies, trying new restaurants, and spending time with friends.

Lauren Rodriguez
4th year PhD student
email: lr66@buffalo.edu

M.A. Psychology, University at Buffalo, SUNY

B.A. Psychology, University of Pennsylvania

Lauren is a fourth year doctoral student in the Alcohol Research Lab. She completed her Bachelor of Arts degree at the University of Pennsylvania, and has earned her Master’s degree at the University at Buffalo. Lauren’s research interests focus on momentary emotional processes and how they contribute to problematic alcohol use among individuals with a history of trauma and posttraumatic stress disorder (PTSD). Currently, she is working on her dissertation which will use a novel experimental paradigm developed at the University at Buffalo to examine the impact of trauma-evoked emotional responses on alcohol consumption and other alcohol-related processes (i.e., reward value, alcohol seeking behaviors, alcohol craving).

In her free time, Lauren loves to salsa dance, watch movies, and go to the park with her Pomeranian named Muffin.
