Modeling Noncondensing Compositional Convection for Applications to Super-Earth and Sub-Neptune Atmospheres

The Astrophysical Journal
Compositional convection is atmospheric mixing driven by density variations caused by compositional gradients. Previous studies have suggested that compositional gradients of atmospheric trace species within planetary atmospheres can impact convection ...

Photoevaporation from water-rich exoplanet atmospheres

Planets orbiting close to their host stars face a significant threat from photoevaporation, which can potentially erode their atmospheres to the point of complete removal.

A New Strategy for Using Spectroscopic Phase Curves to Characterize Nontransiting Planets

The Astronomical Journal
We introduce a new time-series analysis strategy for combined-light exoplanet spectroscopic phase curves called the variable planetary infrared excess (VPIE) method.

The Discovery of Five Hot Jupiters by TESS

The Astronomical Journal
Despite decades of research on hot Jupiters, there are still several theories for their formation. Perhaps hot Jupiters form in several ways. Atmospheric and dynamical studies have the capability to constrain the formation scenarios.

Statistical Trends in JWST Transiting Exoplanet Atmospheres

The Astrophysical Journal
Our brains are hardwired for pattern recognition as correlations are useful for predicting and understanding nature. As more exoplanet atmospheres are being characterized with JWST, we are starting to unveil their properties on a population level.

Rocky exoplanet characterization and atmospheres

, 2012
A decade of exoplanet search has led to surprising discoveries, from giant planets close to their star, to planets orbiting two stars, all the way to the first extremely hot, rocky worlds with potentially permanent lava on their surfaces due to the star ...

Exoplanet atmospheres: physical processes

, 2010
Over the past twenty years, astronomers have identified hundreds of extrasolar planets--planets orbiting stars other than the sun. Recent research in this burgeoning field has made it possible to observe and measure the atmospheres of these exoplanets ...

Characterization of Exoplanet Atmospheres: Spectral Retrieval and Chemistry [PDF]

, 2013
The study of exoplanets is rapidly evolving into an important and exciting field of its own. My investigations over the past half-decade have focused on understanding just a small sliver of what they are trying to tell us.
