Current Research

Michelle Kondo, Ph.D., is a scientist with the USDA-Forest Service, Philadelphia Field Station. She completed doctoral training in Urban Design and Planning at the University of Washington, and postdoctoral training in environmental health and epidemiology at the University of Pennsylvania. Dr. Kondo’s general research interests include:

• Environmental strategies for violence, injury and disease prevention
• Environmental health and environmental justice
• Geospatial and community-based research methods

Her research addresses the following broad questions: What are the health consequences of environmental disparities? By which physiological and psychosocial mechanisms do environments affect health? And, what impact can place-based and nature-based initiatives have on preventing and reducing violence, injuries, and disease? She is also interested in evaluating the influence of community participation in place-based initiatives on health outcomes. Some of her major projects include:

Changes in public health and safety associated with greening of vacant land and other greening and blight-reduction initiatives

Post-industrial cities throughout the Eastern US are developing innovative programs to reuse vacant lots. Cities are increasingly combining goals of vacant land stabilization with sustainability and public health and safety initiatives; vacant lots present opportunities to promote economic development, improve health and safety, and provide ecosystem services such as stormwater management. Dr. Kondo’s research employs quasi-experimental and experimental methods in evaluating impacts of vacant lot reuse and other greening programs such as green stormwater infrastructure on health and safety.

Viability of Prescriptions for Nature Programs

Partnerships between doctors, hospitals, non-profit groups and land managers are developing across the US to initiate “Parks Rx” or “Nature Rx” programs which incorporate support for families in spending more time outdoors in to the medical system. This project evaluates effectiveness of Nature Rx programs in implementation and in increasing patient use of outdoor spaces.

Past Research

Dr. Kondo's past research has investigated patterns of air pollution in goods-movement communities; air pollution-related stress and risk perception; and methods of community engagement in research and planning.
