Area of Specialty 

Analytical and Marine and Atmospheric Chemistry

Research Interests

I am interested in the sources and sinks of biogeochemical trace gases and the effect on atmospheric chemistry and climate as well as the impacts on air quality in the Baltimore region.  I'm also interested in developing projects with students based on their research interests.  For more on research in my group please visit our research group page.  I also maintain a series of air pollution monitors in the area that are accessible in real time.


In addition to the air pollution monitors, I do talks and demonstrations in schools on chemistry or climate change and for general audiences on climate change.  I also organizing the Baltimore Environmental Film Series at Loyola
