Principal Investigator

Aoife O'Donovan, Ph.D.

Principal Investigator

THRIVE Lab Director Dr. O’Donovan completed undergraduate and graduate programs at University College Cork, the National University of Ireland, Galway, and University College Dublin in her native Ireland before coming to UCSF for graduate and postdoctoral training. In her current role as Associate Professor In Residence in the UCSF Department of Psychiatry and Behavioral Sciences and Weill Institute for Neurosciences and Research Psychologist in the San Francisco Veterans Affairs Healthcare System, she runs a laboratory dedicated to uncovering the mechanisms linking psychological stress exposure with ill health. Her lab conducts studies that determine both the effects of psychological stressors on the immune system, and the health consequences of stressor-related immune dysfunction. Many of their findings converge on altered inflammatory activity as a central mechanism linking stressor exposure with increased risk for mental and physical health problems. The lab is particularly focused on traumatic stressors, which are stressors involving threat of death, serious injury, or sexual violence, and posttraumatic stress disorder (PTSD). The ultimate goal is to identify and develop interventions that can reduce the long-term negative impact of psychological stressors. Studies in the lab are currently investigating the potential of both digital app-based and pharmacological interventions. Outside of the lab, Aoife enjoys hiking, biking and skiing in the Bay Area and trips to Ireland.

Emily Dolsen, Ph.D. 

Post-doctoral Scholar/Investigator

Yvette Szabo, Ph.D.

Post-doctoral Scholar/Investigator

Dr. Yvette Szabo is a licensed clinical psychologist and investigator at the VISN 17 Center of Excellence for Research on Returning War Veterans. Dr. Szabo completed her PhD in Clinical Psychology at the University of Louisville, where she received an honor for excellence in graduate studies. She completed her predoctoral internship at the Michael E. Debakey VA Medical Center and a MIRECC advanced postdoctoral research fellowship at the VISN 17 Center of Excellence for Research on Returning War Veterans. Her research investigates the physiological mechanisms through which the environment influences behavior and health. The main focus of her research aims to understand the psychological (e.g., emotional, cognitive) and biological pathways (e.g., inflammation, genetics) through which stress or trauma leads to posttraumatic stress disorder and other negative trauma-related outcomes. Specifically, her lab focuses on examining bidirectional associations between the brain and immune system, as well as understanding how stress and trauma influence these relationships. Her research incorporates a combination of psychological and interdisciplinary methods, including laboratory-based tasks, analysis of blood and saliva samples, and clinical interviews. Through this work, she intends to identify potentially malleable factors and opportunities for novel or personalized interventions to improve health and quality of life in those exposed to stress and trauma.

Amanda J. Khan, Ph.D.

Post-doctoral Scholar/Investigator

D. Parker Kelley, Ph.D.

Post-doctoral Scholar/Investigator

D. Parker Kelley, PhD is a Post-Doctoral Fellow in the Department of Psychiatry and Behavioral Sciences at the University of California San Francisco in the Translating Psychedelic Research (TrPR) program working under Dr. Josh Woolley. Parker is also an affiliate Post-Doctoral Fellow in the THRIVE lab at the San Francisco Veterans Affairs Medical Center (SFVAMC) working under Dr. Aoife O’Donovan.

Dr. Kelley began his post graduate studies at Pennington Biomedical Research Center in the Nutritional Neuroscience and Aging Lab under Dr. Donald Ingram studying the effects of calorie restriction on aging related disease and considers metabolism and allostatic load to be his fundamental orientations to the study of stress-associated disease. Dr. Kelley completed his doctorate in Biomedical Sciences at Louisiana State University studying molecular mechanisms of allostatic load and hippocampal dysfunction in rodent models of Post-Traumatic Stress Disorder (PTSD) and investigating experimental therapeutics for PTSD and depression. Dr. Kelley is trained in molecular biology, psychopharmacology, and behavioral neuroscience. During his doctoral studies, Dr. Kelley utilized multiple omics technologies including RNA Sequencing, LC-MS based Lipidomics, and Metabolomics to study the effects of stress on the hippocampus in rodent models and the effects of an anti-oxidant blueberry concentrate in blood of human patients diagnosed with depression and anxiety. In addition, Dr. Kelley is trained in the use of cutting edge techniques to measure mitochondrial function in tissue samples, the use of behavioral assays to study hippocampal contextual memory processing and pattern separation in rodent models, and psychometric evaluations in humans, all of which he seeks to translate into the study human patients with PTSD during his post-doctoral fellowship. Dr. Kelley is interested in the use of 5-HT2A agonist psychedelic drugs and other experimental therapeutics for PTSD. Dr. Kelley published on the use of pharmahuasca, a drug combination including N, N dimethyltryptamine, a 5-HT2A agonist psychedelic drug and harmaline, a beta Carboline MAOI in a rat model of PTSD progression and observed that pharmahuasca rescues aberrant gene expression in the prefrontal cortex overlapping between the model and human PTSD, and rescues aberrant reactive oxygen species production, indicative of neuroprotective effects. Dr. Kelley is also interested in philosophy of mind and bioethics and is currently working on several projects in this area.

Dr. Kelley was awarded the Heidi Lott Scholarship from the Department of Comparative Biomedical Sciences at Louisiana State University and has published in high impact journals including Geroscience, Journal of Gerontology, Royal Society of Chemistry Advances, and American Chemical Society Chemical Neuroscience.
