Brief Bio
Dr. Kristina Wagstrom is a chemical engineer with a specialization in atmospheric chemistry originally from central Texas. In September 2013, she joined the Chemical and Biomolecular Engineering Department at the University of Connecticut as the Northeast Utilities Assistant Professor of Environmental Engineering Education.
Kristina spent September 2012 – August 2013 as a American Association for the Advancement of Science (AAAS) Science and Technology Policy Fellow in Washington D.C. During her fellowship she was hosted by the National Center for Environmental Research within the U.S. Environmental Protection Agency’s Office of Research and Development.
In 2004, she obtained her B.S. in chemical engineering from the Illinois Institute of Technology in Chicago, IL. In 2009, she obtained her Ph.D. in chemical engineering from Carnegie Mellon University in Pittsburgh, Pennsylvania. Her thesis focused on approaches for modeling source contributions to atmospheric particulate matter concentrations. During her postdoctoral position at the University of Minnesota in Minneapolis, Minnesota, she studied the potential air quality implications associated with using biofuels in place of conventional gasoline.
In her spare time she enjoys playing the flute, STEM outreach, scuba diving, and travel.
– Source contributions to atmospheric particulate matter concentrations

– Enabling community action around local air pollution concerns
Global particulate matter source apportionment: We are currently working to implement a source apportionment schema into a global atmospheric model (specifically GEOS-Chem). This work is aimed at providing the atmospheric community with the tools to better track source-specific pollutant transport and transformations at the global scale. While this type of schema is available in regional and local scale models, a full particulate matter source apportionment scheme is not currently available in a global atmospheric chemistry model. This work will allow for a improved estimation of the impacts of long-range pollutant transport on human health, ecosystems, and climate.
Modeling over multiple scales: One of the challenges in air pollution modeling is the different scales over which pollutant concentrations can vary, from a plume being emitted by the bus that passes you on the street to large scale intercontinental transport. Our goal is to develop techniques that allow us to model air pollutant concentration gradients efficiently over a variety of scales.
Low-cost air pollution monitoring: A variety of low-cost air pollution monitoring sensors have recently been entering the market. In general, these devices are not considered to be particularly accurate but have potential for citizen science applications. We are interested in determining if using the relative values of the sensors might provide information that can be used to evaluate high spatial resolution modeling applications.
Nitrogen deposition to United States watersheds: Air pollution can have a significant impact on watersheds as it deposits on land and water. This project will use air pollutant deposition estimates from the CAMx regional air pollution model in conjunction with watershed classifications from the U.S. Geological Survey to determine watersheds that are in the most danger due to pollutant deposition.
