Personal Statement

My public health work and research merges health behavioral theory, social network analysis, and systems science, to generate new understandings of how social systems impact human health. Findings emerging from my research show that social networks and health behaviors evolve in mutually dependent ways: social selection based on similarities in attributes and behaviors create social groupings with particular social and behavioral norms, and these social groups subsequently shape and reinforce behavior in ways that have profound impacts on health and wellbeing. My current work is focused on developing health interventions that integrate social networks and systems science, as well as big data and mobile health technology, to promote healthy outcomes--in particular healthy eating and weight--in priority populations
