The evolution of Earth's climate past present and future. Over the course oy my career I have used 3D models to investigate how Earth's climate system evolves due to radiative and cloud effects. I have studied solutions to the so-called Faint Young Sun Paradox (i.e. how did the ancient Earth stay warm and habitable despite ~25% less solar energy), the fate of Earth in the distant future as the Sun gradually brightens over time, the co-evolution and climate sensitivity due to changes in CO2 and the solar constant, and the effect of fractal aggregate hazes on early Earth. Work continues with colleagues and collaborators on paleoclimates and future Earth scenarios.
overview
Over the past decade I have worked on numerous NASA sponsored projects that cross boundaries between climate, planetary, and space sciences. I have studied numerous topics including the evolution of Earth's climate through time, the Faint Young Sun Paradox, moist and runaway greenhouse climates for future Earth, the habitability of extrasolar planets, the characterization extrasolar planets through transmission and thermal emission spectra, and the microphysical and optical properties of fractal aggregate aerosols.
My primary tools are 3D general circulation models, radiative transfer models, and cloud and aerosol microphysical models. I am perhaps most known for developing and supporting ExoCAM, an extension of the National Center for Atmospheric Research's Community Earth System Model that facilitates modeling of exotic (non-Earth-like) atmospheres. At the heart of ExoCAM is a ExoRT, a flexible two-stream correlated-K radiative transfer model. ExoCAM and ExoRT are used by many research teams around the world. I maintain strong interest in open-source software and building tools that are broadly useful to the community.

recent highlights
- [October 7th, 2025] New paper on TRAPPIST-1 e chemistry, climate and transmission spectral modeling. This work takes a novel approach of considering a quasi-monte Carlo sparse grid while employing Kriging (i.e. gaussian process emulation) to emulate the full parameter space. See our work published here.

Earth Climates Past, Present, and Future
Modeling (exo)Planetary Atmospheres
Using 3D climate models to map the habitable zone and predict observations. I use 3D climate models to explore extrasolar planets and the so-called "habitable zone." Studies have included specific planet targets (TRAPPIST-1 e, TOI-700 d , GJ 251 c Kepler-1649 c , generic tidally locked terrestrial planets around M-dwarf stars, and circumbinary planets . My work has been foundational in mapping the habitable zone and exploring concepts on the runaway and moist greenhouse processes, and cloud-convection feedbacks. As always, my end-goal is to connect simulations of planetary atmospheres to observable metrics.
ExoCAM/ExoRT Open-Source Tools for Climate Modeling
Primary developer and maintainer for ExoCAM. ExoCAM is a 3D climate model for exoplanet atmospheres based on the National Center for Atmospheric Research Community Earth System Model (CESM). ExoCAM expands CESM users to simulate a wide variety of planetary atmospheres, relevant to past, present, and future Earth, solar system bodies, and extrasolar planets. At the heart of ExoCAM, is ExoRT, a flexible two-stream correlated-k radiative transfer model which expands the model capabilities to allow diverse atmospheric compositions, and input stellar spectra. ExoCAM and ExoRT are currently used by research groups on 3 continents, studying topics from Earth's future climate, terrestrial M-dwarf planets, mini-Neptune planets, planets around white dwarf stars, among other topics. The code is publicly available on GitHub for ExoCAM and ExoRT. I am committed to building robust, open-source software for the global planetary science community.

about me
I'm lucky to call the mountains of Breckenridge, Colorado my home where I live with my wife and our two Giant Schnauzers. Living at 9,600 feet provides a great backdrop for my main hobbies: skiing in the winter and mountain biking in the summer. I also recently started playing tennis again after a 20 year break, I ceaselessly listen to music (electronic and '90s), and I dabble in investing, philosophy, mindfulness, yoga, travel, reading, and experiencing life to its fullest.
