Her research uses atmospheric chemistry modeling to inform decision-making on air pollution, climate change and hazardous substances such as mercury and persistent organic pollutants (POPs). Professor Selin received her PhD from Harvard University in Earth and Planetary Sciences as part of the Atmospheric Chemistry Modeling Group, where she developed and evaluated a global, 3D model of mercury pollution. Prior to her current appointment, she was a research scientist with the MIT Joint Program on the Science and Policy of Global Change.
