Welcome to subramanian's webpage
I am a mechanical engineer who does research in atmospheric chemistry and environmental science, currently focusing on these three areas as a research scientist at the Center for Atmospheric Particle Studies at Carnegie Mellon University:
- Low-cost air quality monitoring in the US and other countries. (Check out the RAMP sensors page.)
- Studying the impact of atmospheric aging and biogenic emissions on the optical properties of soot aerosols (a major climate forcer) emitted by cookstoves, diesel engines, and other combustion sources, through laboratory and field measurements.
- Quantifying the leak rate of methane (a potent climate forcer) from the US natural gas infrastructure, as well as that of co-emitted pollutants.
July 2017: #DayOfScience #ScienceAthon fundraising tweets for the Earth Science Women's Network.
July 2017: The Pittsburgh Post-Gazette interviewed us on low-cost air quality monitoring in EJ areas.
June 2017: Here is an interview I did with the Allegheny Front on low-cost air quality monitoring in environmental justice areas.
November 2015: Video of a talk I gave on our methane emissions measurements to the Pipeline Safety Trust.
