Research Assistant Professor, Social Environment and Health Program
As an environmental epidemiologist and with funding from the National Institute of Environmental Health Sciences, the National Science Foundation, and Detroit community input, I study how social, economic, health, and built environment characteristics and/or air quality affect vulnerability to extreme heat and extreme precipitation. This research will help cities understand how to adapt to heat, heat waves, higher pollen levels, and heavy rainfall in a changing climate.
I received my BA in Biology from the University of Chicago, with a specialization in Ecology and Evolution. Subsequently, I worked as a research assistant in the Clinical Trials Office at the Karmanos Cancer Institute in Detroit, MI before pursing a Masters in Public Health at the University of Michigan. I completed my MPH in 2008 and then completed my PhD in 2013 in the University of Michigan Department of Environmental Health Sciences, where I was a National Institute on Aging Public Health and Aging trainee. My dissertation focused on associations between high temperatures and hospital admissions and mortality among the elderly as well as sociodemographic and land cover characteristics that modify these associations. In my postdoctoral fellowships, I studied how social and environmental characteristics influence vulnerability to heat-related health effects, using data from longitudinal studies of cardiovascular health in seven U.S. cities as well as state and national records of severe health events.
Climate Change and Allergies (Institute for Global Change Biology)
With climate change, pollen levels are rising in many parts of the country. Using a new daily speciated pollen model, we are estimating the onset and time course of allergy and asthma symptoms in people with allergies as well as associations between asthma emergency department visits and different species of pollen in the Industrial Midwest.
Energy Justice, Housing and Health in a Changing Climate (M-Cubed, with Tony Reames and Marie O’Neill)
Low and moderate income households face increasing challenges regarding household energy insecurity. Additionally, a changing climate with increased extreme weather may exacerbate weather-related health effects, This project aims to characterize and map the health and economic burdens of housing quality, air pollution, and energy insecurity
Causal Mechanisms for Sustainable Adaptation to Adverse Heat and Precipitation Health Effects
Wide socioeconomic disparities exist in weather-associated morbidity and mortality. Using novel data linkages while working with local officials and community leaders to understand the housing and health characteristics that increase vulnerability to heat-and precipitation-associated health effects will help identify optimal and sustainable strategies for adapting to increasing extreme weather events
