Jim Crawford received his B.S. in Mathematics from the United States Military Academy in 1986 and his Ph.D. in Atmospheric Chemistry from the Georgia Institute of Technology in 1997. Since that time, he has been a research scientist at NASA’s Langley Research Center. From the start of his graduate studies in 1991 and throughout his career, his research has been associated with airborne field studies conducted across the globe by NASA’s Tropospheric Chemistry Program and collaborating partners.



IGAC has a strong focus on engaging the next generation of atmospheric scientists through its early career program.  These scientists join an international network early in their career that creates relationships that facilitate atmospheric chemistry research at an international level for years to come.

IGAC cultivates the next generation of scientists by:


Hiroshi Tanimoto is the Head of Global Atmospheric Chemistry Section at National Institute for Environmental Studies (NIES) in Tsukuba, Japan. He received his PhD in Chemistry from The University of Tokyo in 2001 and was a visiting scholar at Harvard University during 2007–2008. Dr. Tanimoto has been working in the field of atmospheric composition in Asia and Oceania regions.



Mark Lawrence is a scientific director of the cluster “Sustainable Interactions With the Atmosphere” (SIWA) at the Institute for Advanced Sustainability Studies (IASS, www.iass-potsdam.de) in Potsdam, Germany.




Manish Naja is a senior scientist and vice-chair of Solar Physics and Atmospheric Science group at ARIES, Nainital. He pursued his doctoral research work at PRL, Ahmedabad and has worked as a postdoctoral scientist at FRCGC, JAMSTEC, Yokohama and NIES, Tsukuba, before joining ARIES. His major research interest has been in the observations of the trace gases using surface based, ship-borne and balloon-borne instruments. He has been involved in INDOEX (Indian Ocean Experiment), GOSAT (Greenhouse Gases Observing SATellite), GVAX (Ganges Valley Aerosol Experiment) programs.
