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!
