Research Interests:
1. Field Measurements of Trace Gas and Aerosol Pollutants.
I supervise a rural atmospheric chemistry field station at Pinnacle State Park in Addison, NY that has
been in operation since 1995. At the site we make continuous, year-round measurements of some two dozen
physical and chemical parameters important to atmospheric chemistry and air pollution. I have also organized
and managed special field studies in New York City.
2. Instrument and Method Development and Evaluation for Continuous Measurement Systems.
We are particularly interested in the development and evaluation of continuous measurement systems that can
be operated 24/7/365 to provide data over seasons and years. I have worked with systems for the measurement of
nitrogen dioxide (NO2), ammonia (NH3), nitric acid (HNO3), and formaldehyde (HCHO) on the trace gas side; and
sulfate, nitrate, and carbon on the aerosol side.
3. Laboratory Measurement of Aerosol Chemistry and Dynamics, and Evaluation of Instrumentation.
This work is in collaboration with Research Scientist Olga Hogrefe.
