Kobi Abayomi has graduated as a doctoral student in Statistics with a minor in Environmental Engineering. After serving as a postdoctoral fellow at Duke University, Kobi accepted an Assistant Professorship at Georgia Tech. His research interest lies in applying quantitative methods to environmental concepts such as sustainability, economic value, and disaster risk. He hopes to show that an investigation of dependence in a jointly distributed ranking of environmental and non-environmental goods can argue for the primacy of the environmental goods, which actually have values far greater than those usually assigned in current market valuation models. Currently he's specifically working on welfare functions and ranking statistics.

Kobi loves to swim, ride any type of cycles, argue, and play old music.

Christy Field is a graduate student in the Department of Earth and Environmental Studies. Her research focuses on assessing the usefulness of the cosmogenic isotope beryllium-10 as a proxy for solar irradiance changes. By using the Goddard Institute for Space Studies ModelE general circulation model, she hopes to develop a better understanding of how climate-related and production-related changes in the isotope record can be calibrated to solar climate forcings.

In addition to unravelling the mysteries of beryllium-10, Christy loves cooking and baking, exploring New York and playing tennis if the weather's nice.

Deborah Herceg has graduated as a doctoral student in Applied Mathematics. She is currently a postdoctoral fellow at Rutgers University. Her main research interests are the regional climate modeling, atmospheric science and climate change scenarios. She works in conjunction with the International Research for Climate Prediction (IRI) at Lamont. Her research examines and classifies the errors generated by the regional climate model, NCEP RSM 97, thru so-called Big Brother experiment. The .pdf version of the early submitted paper can be viewed at: www.columbia.edu/~ahs129/Papers/herceg_etal_submitted.pdf. She currently works on the regional modeling of the Sahelian region that has experienced a serious drying trend since 1970s (in comparison to 1950s). She is examining this interdecadal drying trend thru numerous regional and global model simulations.

Deborah enjoys running and many outdoor activities. She is currently in training for the Air Force Marathon that will take place on September 17, 2005 at Wright-Patterson AFB, Ohio. She loves traveling and exploring; just about the most beautiful place (besides Croatia) is definitely Greenland.

Kirk Knobelspiesse is a doctoral student in Applied Mathematics. He arrived at Columbia by a rather circuitous route, starting with an undergraduate degree in photography, a master's degree dealing with remote sensing of the earth, and several years working on an oceanographic carbon cycle project at NASA Goddard Space Flight Center. While at Columbia, he hopes to strengthen his knowledge of mathematical fundamentals and concentrate on Atmospheric Science, specifically on the role that aerosols play in radiative transfer.

Beyond studies, Kirk likes traveling, backpacking, pretending to be a photographer, and exploring his new home in New York City.

Jonathan Levine is a student on the doctoral track in the Department of Earth & Environmental Engineering. His academic interests focus on water and energy issues, and his research will be in high-coefficient-of-performance heat pumps for use in small-scale water purification in rural areas of developing countries.

Jonathan can be found playing soccer on the South Lawn nearly every day, and he does his best to rely solely on his bicycle for his transportation needs. Compared to his IGERT peers, he is largely uncultured and talentless, with his only mark of distinction being that he is a registered member of the Green Party.

Brice Loose is a doctoral student in Earth Sciences. He uses tracers and inverse models to study circulation and mixing in the ocean and in groundwater. Geochemical tracers can provide quantitative descriptions of flow and exchange between reservoirs where physical measurements and modeling break down. But the interpretation of these integrated signals is a dark art and sometimes requires more than a little math.

In his free time, Brice wonders why he doesn't have much free time.
