Hello! I’m Qiang Pu, a Postdoctoral Fellow in the Gangarosa Department of Environmental Health, at the Emory University. Currently, I’m working with the Emory Environmental Remote Sensing Group. My research interests lie at the intersection of GIScience and environmental health, where I model the spatiotemporal distributions and uncertainties of ambient environmental exposures (e.g. air pollution and heat). I use advanced geospatial technologies, such as geostatistics/machine learning models, satellite remote sensing, GPS, and GIS, to provide insights into potential health impacts and support evidence-based policy and decision-making.

I received my Ph.D. in Geography from University at Buffalo, SUNY, an M.S. in Cartography and GIS and a B.S. in Geomatics Engineering from the School of Geosciences and Info-physics at Central South University.

Here is my CV.

  • Air pollution modeling
