Ying joing the group in 2007. She was interested in health effects of particulate matter. She participated in the Los Angeles Air Basin Mobil Study I and in the 2007 San Diego Fires.

Currently at a second post-doc position at UCLA

Dr Hiroshi Furutani (2001-2007)

Hiroshi studied the ejection of aerosols from bubble bursting and marine organisms on particles, looked at gold nanoparticles with the ATOFMS and lead the beginning of the development of the new Chemical Ionization - Aerosol Time of Flight Mass Spectrometer (CI-ATOFMS).

Currently a Research Fellow at the Ocean Research Institute at the University of Tokyo

Dr Thomas Rebotier (2004-2006)

Thomas contributed to our software all along the data processing chain, from instrumental signal processing to classification to result-presentation.  His research topics included cars vs. diesel truck aerosol apportionment, large dataset classification, and making aerosol classification robust with respect to particle aging.

Maggie Yandell

Maggie worked with the Prather group since she was a freshman. Her primary focus has been contributing during field studies and analysing data from Long Beach. She also worked on the health effects project in colloraboration with Professor Mike Tauber. She is currently a chemistry graduate student at UC Berkeley.

Brandon Heilman

Brandon was part of the lab between Spring 2008 until he graduated in Spring 2009. He worked on quantifying chemical standards and analyzing firework fingerprints. He is now a chemistry graduate student at UC Santa Cruz.

Rene Sanchez

Rene worked with the Prather group from June of 2004 until August 2006.  His primary focus has been to develop the operating system for the Aircraft-Aerosol Time-of-Flight Mass Spectrometer (A-ATOFMS) using LabVIEW. Rene is working on his PhD in Mechanical Engineering with an emphasis in controls at UC Berkeley.

Jessie Charrier

Jessie is a fourth year chemistry major at UCSD and has been working with the Prather group since the spring of 2004.  Her primary focus has been to investigate the ability of salt aerosols produced by air bubble bursting to transport an organic surfactant into the aerosol phase.  After graduating in June Jessie is planning to work in industry for a year and then go to grad school and get her PhD.
