Brief Bio

Dr. Michael D. Himes is an Assistant Research Scientist working with Dr. Natalya A. Kramarova on machine learning applications to measurements by the Ozone Mapping and Profiler Suite's Limb Profiler (OMPS LP) instrument. Himes has developed a near-real-time retrieval algorithm for aerosol extinction from OMPS LP measurements.


As part of a dissertation at the University of Central Florida, Himes developed open-source software packages centered around training and applying neural network surrogate models, Bayesian inference frameworks, and exoplanet atmospheric retrieval.
