Richard Collins
Dr. Collins joined the institute in 1994 as a member of the space physics group. He works in the field of optical remote sensing with an emphasis on laser radar (lidar) techniques. His interests also include the structure and dynamics of the middle atmosphere. Dr. Collins also teaches in the atmospheric science program.

Dr. William Bristow's current research interests include included studies of winds in the upper atmosphere, studies of the magnetosphere-ionosphere coupling, and space-weather effects on radio propagation, which directly impacts radio communications in high-latitude regions. Dr. Bristow is the principle investigator for the SuperDARN network which consists of two radar systems in Alaska.

The greatest light show on Earth: Conde, Lummerzheim featured in BBC Nature story
A BBC Nature report released today features two professors from the Geophysical Institute's Space Physics and Aeronomy group -- Mark Conde and Dirk Lummerzheim. Both scientists are quoted in the story that relays how sounding rockets allow researchers to better understand the aurora and dynamics of the upper atmosphere.
