Kirchstetter's research interests include: 

  • Air pollution science & technology: pollutant emissions and controls with a focus on the transportation sector
  • Characterization and environmental impacts of carbonaceous aerosols
  • Low-cost sensor development; community air monitoring
  • Municipal solid waste-to-energy, evaluation of benefits and barriers to commercial scale-up
  • Mobility: energy impacts of emerging megatrends in people and freight movement

Kirchstetter's research group is studying clean energy technologies, developing novel air pollution sensors, and evaluating in-use pollutant emissions and controls. Current research projects include:

  • Evaluating the emission impacts of new after-treatment control technologies on in-use heavy-duty diesel trucks
  • Quantifying air pollutant and greenhouse gas emissions from dry anaerobic digestion and composting of municipal solid waste-to-energy
  • Developing low cost particulate matter and black carbon sensing technologies, and community air monitoring
  • Developing and implementing new methods of quantifying pollutant emissions from trucks, trains, and marine vessels

I was born and raised in Queens, New York.  In public middle school, I enjoyed math and various shops (yes, public schools used to have wood, metal, and other shops).  Good at math, I left for SUNY Albany to study math and become an actuary.  The fit wasn't great and I was turned on to atmospheric science by enthusiastic professors Volker Mohnen and Bernie Vonnegut.  After college, I worked in a combustion lab at Brookhaven National Lab in Long Island, New York, before heading to UC Berkeley for graduate school.  I've lived in Berkeley and neighboring cities ever since.  

Today, I still enjoy math and science, but in lieu of a shop, I have an aerosol laboratory and I enjoy conducting experiments and collaborating with students and research colleagues.  

Away from work, I enjoy playing music, hiking, camping, cooking, and spending time with family and friends. Thanks to the enthusiasm of my son, Zachary, I've been getting back into fishing, which is something I grew up doing with my dad on lakes and on the Great South Bay of Long Island.
