Ofir received his PhD in physical chemistry from the Hebrew University of Jerusalem for his work on ultrafast pump-probe spectroscopy, and has worked as a senior researcher in spectral remote sensing in the Environmental Physics Department at the Israel Institute for Biological Research. Here he will continue to work on projects related to remote sensing as well as investigating aerosol chemistry.

David Long, who now works at the National Institute of Standards and Technology on projects related to environmental health and greenhouse gas measurements, was of this year's PECASE (Presidential Early Career Award for Scientists and Engineers) awardees. He was given the award for his measurements on carbonaceous pollutants and trace gases, as well as his commitment to mentoring younger scientists.

The newest member of the Okumura team, Caltech undergraduate in Chemistry Katerina Gorou, was awarded the John Stauffer Summer Undergraduate Research Fellowship (SURF). Katerina's proposal centered around hydrogen escape from the Martian atmosphere, and suggested both laboratory and modeling approaches to help explain current deuterium and hydrogen concentrations.

Over the summer, Robin worked with Doug and Tzu Ling on constructing the mid-IR ringdown cavity and vacuum system for the methane kinetic isotope effect project. After construction, they investigated the impact of isotope (deuterium and carbon-13) substitution on the rate of hydrogen abstraction by O1D and chlorine radical. He is now continuing his master's work in France and we will miss him very much!

After completing their theses "Atmospheric Peroxy Radical Chemistry Studied by Infrared Kinetic Spectroscopy" and "Kinetic and Spectroscopic Studies of Atmospheric Intermediates" Aileen and Matt (respectively) move on to their new positions at JPL and Enthought!
