Brief Bio


Michael D. Himes is a NASA Postdoctoral Program Fellow working with Dr. Natalya A. Kramarova on machine learning applications to measurements by the Ozone Mapping and Profiler Suite's Limb Profiler instrument.


As part of their dissertation work 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.
