Research Interests

I study interactions between the terrestrial biosphere and the atmosphere. For one area of focus, I study how biogenic volatile organic compound (BVOC) emissions from plants affect atmospheric chemistry and how climate change will impact this interaction in the future. I also employ low-cost, high-altitude balloon systems to measure the carbon dioxide exchange over agricultural regions in Illinois. Another area of interest is the use of low-cost, wearable air quality sensors for citizen science.
