Research Interests

My research interests are interdisciplinary, lying at the intersection of health, clinical, and social psychology, as well as immunology and microbiology. Humans are fundamentally social beings, and our connections with other can both provide us with opportunities for support and nurturance as well as be potent sources of stress and pain. I conduct research that tries to uncover the psychological and biological mechanisms through which our social relationships affect our physical and psychological health and well-being. I am particularly interested in understanding the role our immune system plays in linking problems we experience within our social relationships to our health.
