WendY Berry Mendes

Lab Director


Dr. Mendes is the Sarlo/Ekman Professor of Emotion at UC San Francisco. Her research questions sit at the intersection of social, personality, and biological psychology and primarily concerns questions regarding embodiment: how emotions, thoughts, and intentions are experienced in the body and how bodily responses shape and influence thoughts, behaviors, and emotions. Some current research areas include coping with stigma and discrimination, dyadic intergroup interactions, affect contatgion, mind-body relations across the life  course, influence of emotional labeling on emotional experience and effects of stress on decision-making.

Amie Gordon

Research Scientist


Dr. Amie M. Gordon is a Research Scientist in Health Psychology. Amie received her PhD in Social-Personality Psychology from UC Berkeley. In her work, Amie draws upon social, personality, and health psychology to explore the factors that shape interpersonal relationships. She takes a multilevel approach, examining social-cognitive, affective, and biological processes that influence interpersonal behaviors and outcomes. In the EHP Lab, she is focused on elucidating the links between sleep and interpersonal functioning by using a dyadic perspective to capture how people's sleep affects their own thoughts, feelings and behaviors as well as the thoughts, feeling, and behaviors of those around them.

Michael Trujillo

Post-Doctoral Fellow


Dr. Michael Trujillo is a post-doctoral fellow in the Center for Health and Community at UCSF. He received his PhD in Health Psychology from Virginia Commonwealth University. His research is centered on understanding how stigma “gets under the skin” to impact mental and physical health. His research is guided by ecological models that view stigma as a fundamental cause of health outcomes and examines how interpersonal, intrapersonal, and structural forms of stigma, particularly those relating to sexual orientation and gender identity, impact health disparities. In the EHP Lab, he is extending this work to decision-making and the role of affectivity.

Lauren Whitehurst

Post-Doctoral Fellow


Dr. Lauren Whitehurst’s research interests broadly entail exploring processes during sleep that are important for health and cognitive function. Her research explores how autonomic and central nervous system factors interact to produce regulatory effects on sleep-dependent health and cognitive outcomes.

Kimberly Lockwood

Post-Doctoral Fellow


Kimberly Lockwood is a post-doctoral fellow in the Center for Health and Community at UCSF. She received her PhD in Biological and Health Psychology from the University of Pittsburgh. Her research focuses on physiological mechanisms that link psychosocial stress with physical health, particularly cardiovascular disease. Her recent work explores how discrimination and other stressors may contribute to racial and socioeconomic disparities in cardiovascular disease risk.

Forrest Rogers

Doctoral Candidate


Forrest D. Rogers, M.A., is a doctoral candidate in biological psychology at the University of California, Davis, where he is a trainee of Dr. Karen L. Bales. Forrest is a pre-doctoral trainee in the NIH-sponsored (T32) Affective Science Training Program, through which he receives additional training in human emotion, health, and psychophysiology from Dr. Wendy Berry Mendes at UCSF. He received his B.A. in French and B.S. in Biological Science with College and Departmental Honors from Oklahoma State University. Forrest studies both prairie voles (Microtus ochrogaster) and humans to explore how parent-child social interactions shape affective/emotional and bio-behavioral development. He is particularly interested in the relationship between hormones, affective states and behavioral processes. (e):
