Professor Matthew J. Zawadzki joined UC Merced in July of 2014. He received his Ph.D. in Social Psychology and Women’s Studies from The Pennsylvania State University in 2012, and completed a two-year post-doctoral fellowship in the Department of Biobehavioral Health at The Pennsylvania State University. Broadly, his research applies social psychological theory to understand the relationships between stress and health. His work aims to understand how thoughts, such as rumination and worry, can create, worsen, and extend stress responses, and explain why stress is so deleterious to health.
