Research Interests: close relationships, psychophysiology, mental health

Leigh is a 5th year doctoral student in Social Psychology at the University of California at Davis. She earned her M.A. in Human Development & Family Sciences in 2016 from the University of Texas at Austin, and her M.A. in Social Psychology from UC Davis in 2018. Leigh has also studied Physics and Applied Mathematics extensively, worked as a programmer and project director in the tech industry, and has strong expertise in advanced statistical techniques and data visualization.

Broadly, Leigh’s research sits at the intersection of social psychology, biological psychology, and mental health. Her current research explores how social relationships influence psychological and physiological outcomes related to health and well-being. At present she is directing a research project investigating the ways in which social psychological principles can be used to improve the relationship between mental-health practitioners and their clients, where the outcomes of interest are both intra-personal in nature (e.g., increasing client self-efficacy, reducing practitioner burnout, improving stress reactivity in both) and interpersonal in nature (e.g., fostering greater trust, investment, and satisfaction within the therapeutic relationship).

Leigh has extensive training in measuring and analyzing a range of physiological indices including cardiovascular processes (e.g., impedance cardiography, ECG, continuous and acute blood pressure) and neuroendocrine processes (e.g., collecting and assaying salivary cortisol, DHEA, α-amylase). She has also published work reviewing the ways in which our internal microbial populations impact psychological outcomes (affect, cognition, social relationships).

As a biracial woman in STEM, Leigh is dedicated to providing professional and academic mentorship to young men and women of color, and currently supervises a talented team of undergraduates studying psychology, neuroscience, and communications. You can learn more about this research team here.
