Dr. Johnson earned her B.S. in Physics with a minor in Mathematical Sciences from Michigan Technological University and her Ph.D. in Atmospheric Science from Purdue University.
Her work has tackled a wide range of topics and scientific methods including airborne measurements of water vapor in pre-depression areas over the Atlantic, laboratory studies of water ice nucleation in the atmospheres of Earth and Mars, and high-resolution single cloud models for comparison with maritime cumulus observations.
Most recently she has become interested in laboratory studies pf planetary atmospheres and clouds. This includes the current and former atmospheres of our nearest neighbors (Mars, Venus) and moons (Titan), and the atmospheres of planets further away (Exoplanets).
