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.
Assessing the Neuropsychological Benefits of Weatherization Programs
Modifications to homes that increase energy efficiency and improve indoor temperatures may reduce the health impacts of extreme temperatures and financial stress. We will characterize and monetize the health impacts of low-cost and higher-cost weatherization measures, which may improve the health of older adults through improvements to sleep, cognitive function, and financial worry as well as community-wide reductions in air pollution exposure. Weatherization interventions may allow older adults to both mitigate and adapt to extreme weather.
SCC-IRG Track 1: Reducing Barriers to Residential Energy Security through an Integrated Case-management, Data-driven, Community-based approach
The goal of this Smart and Connected Communities (SCC) project is to explore the efficacy of new social-technological paradigms to reduce residential energy insecurity for low- and moderate-income (LMI) households in three neighborhoods in Detroit, Michigan, which is one of the top ten highest energy burdened metros in the US.
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.
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
