Biological, Cognitive and Social-Emotional
B.A., Psychology (California State University, Northridge)
I am a third-year Human Development NSF-GRFP Research Fellow in the Department of Human Ecology at the University of California, Davis. I work under the supervision of my primary graduate advisers Drs. Paul D. Hastings in the Department of Psychology and Amanda E. Guyer in the Department of Human Ecology. My research focuses on three interconnected areas:
1) The intersection of ethnic/racial and sexual minority identities. Specifically, I study the effects of compounded ethnic/racial and sexual minority prejudice (i.e., stress) on physiological self-regulatory mechanisms via hypothalamic-pituitary-adrenal axis and immune system functioning, and in turn, their effects on psychosocial adjustment (e.g., depression). I also seek to identify resilience factors such as parent and peer social support and coping strategies to help ameliorate the adverse effects of prejudice in sexual minority people of color. This is study is funded by the American Psychology Foundation's Wayne F. Placek Grant awarded in 2015. http://www.apa.org/apf/funding/placek.aspx?tab=1
2) I also am interested in peer-relationship processes during adolescence, particularly in ethnic minority youth of Mexican-origin. I am particularly interested in emotion regulation processes via parasympathetic system activation (e.g., heart rate variability and RSA) when adolescents experience rejection by peers and their effects on psychosocial adjustment.
3) Lastly, I am interested in methodological issues associated with retrospective reports of peer victimization. In collaboration with Dr. Adrienne Nishina in the Human Development Graduate Group at UC Davis, using data from the UCLA Peer Project, we are testing how retrospective and concurrent reports of peer victimization are related to adolescentsí psychosocial adjustment.
During my free time, I run. I also love to cook, bake, learn about different grape varietals, and occasionally draw or paint.
