Dr. Gimmestad received the B.A. degree in Physics from St. Olaf College in 1968, and the M.S. and Ph.D. Degrees in Physics from the University of Colorado in 1972 and 1978. His doctoral research was on the millimeter-wave spectrum of oxygen.

From 1978 to 1986, Dr. Gimmestad was an Associate Professor of Physics and a Senior Research Scientist at Michigan Technological University. His research work was primarily on atmospheric optics at visible and infrared wavelengths.

Dr. Gimmestad joined the Electromagnetics Laboratory of the Georgia Tech Research Institute in 1986 as a principal Research Scientist. He heads a group of atmospheric laser radar (LIDAR) researchers who are developing laser-based atmospheric remote sensing systems for a broad range of applications including air quality, military test range support, and astronomy. The group also promotes LIDAR education through short courses and collaborations with other institutions.

Research interests: 
  • Optical systems for remote sensing of the earth's atmosphere
