Camelia Hostinar is an Associate Professor in the Department of Psychology. Dr. Hostinar studies how the social environment shapes health, with a focus on the activity of stress-response systems. She is examining the pathways linking early-life stress to later disease and investigating protective processes that could modify these adverse trajectories.

She operates the Social Environment and Stress (SES) Lab, in which she welcomes the participation of graduate students with interest in this area of study.

She also is affiliated with the UC Davis Center for Poverty Research.

Research Focus

Dr. Hostinar researches the ways in which childhood poverty and other forms of early-life adversity influence later development and health. She has particular interest in protective factors that may buffer children and adolescents from chronic stress and subsequent physical or mental health problems. Her research examines developmental processes at multiple levels of analysis, incorporating endocrine and immune biomarkers, electrophysiological data, genetic assays, and behavioral measures. She seeks to improve understanding of the role of early-life stress in shaping self-regulatory skills, and to illuminate how stress-buffering processes such as supportive social relationships exert their effects.
