Research Interests

  • Health Effects - Chemical characterization of potentially toxic or carcinogenic particulate matter, new technique development to characterize organic functional groups using FTIR and characterize elements using high-volume sampler and ICP-MS, radical generation due to particles in surrogate lung fluid.
  • Urban and Regional Smog - Laboratory studies of the formation of secondary organic aerosols.
  • Visibility Degradation - Work with the IMPROVE group at UCDavis which measures the concentration and composition of visibility reducing particles in all the National Parks in the U.S.
  • Global Climate Change - Atmospheric transformation of organic particles and their impact on regional climate.

Research Summary

My research focuses on characterizing the chemical composition of atmospheric particles and using this information to better understand sources of particulate matter, visibility degradation, health impacts and climate change. I have recently developed a novel techniques to characterize the organic fraction of particulate matter, the least understand component of particulate matter.

Teaching Summary

I teach undergraduate air pollution courses in Civil and Environmental Engineering (ECI 149) and Land, Air and Water Resources (ERC 131).
