Dr. Timothy Killeen, Assistant Director for the Geosciences, National Science Foundation (NSF)

Tim was appointed NSF’s Assistant Director for the Geosciences in July 2008. In this role, he oversees the Geosciences Directorate (GEO), which supports research in the atmospheric, earth and ocean sciences including climate processes and changes, the water cycle, and natural disasters such as earthquakes, tsunamis and severe storms.

Prior to this appointment, he served as director of the National Center for Atmospheric Research (NCAR) since 2000. Before that, he was Professor of Atmospheric, Oceanic and Space Sciences, Associate Vice President for Research, and Director of the Space Physics Research Laboratory at the University of Michigan. He has held leadership roles in the geosciences for many years, including chairing numerous national committees and advisory panels. He served as president of the American Geophysical Union from 2006-2008, and is a member of the National Academy of Engineering. His research interest is in satellite measurements and modeling of the upper atmosphere. He holds a doctorate in atomic and molecular physics and a B.S. from University College London.

Tim is married, and is the father of three wonderful kids!
