Dr. Lydia Roos is an interdisciplinary stress researcher and postdoctoral fellow in UCLA’s Semel Institute for Neuroscience and Human Behavior. She obtained her PhD in Health Psychology from the University of North Carolina at Charlotte. Dr. Roos’ research investigates the psychological, biological, and social mechanisms underlying the links between stress and health, and how coping and emotion regulation strategies as well as social processes confer risk for—or resilience against—worsened health via altered stressor perceptions and psychobiological reactivity. She is passionate about expanding access to training in stress, health, and resilience, both for professionals and the public.

Dr. Michael Snyder is the Co-Principal Investigator of the CAL STAR Network and an expert in molecular genetics who uses a precision medicine and multi-omics approach to genome sequencing and health.

Dr. Daniel Moriarity’s research program focuses on three intersecting aims: 1) the integration of inflammatory processes into robust, extant psychosocial frameworks of psychopathology risk, 2) characterizing inflammatory phenotypes of psychopathology, and 3) investigating and leveraging measurement characteristics of biological variables (i.e., physiometrics) to improve the methodological rigor of biological psychiatry. By contributing to growth in these three areas, Daniel hopes to contribute to maximizing the replicability of immunopsychiatry research and understanding of how (and for whom) the immune system is associated with psychiatric symptoms. He received his undergraduate training at Elmira College, completed his Doctoral Program at Temple University, and has done a clinical internship at Harvard Medical School. He has clinical training, quantitative expertise, multi-model dissemination experience, and professional development mentoring experience.
