My research entails understanding the atmospheres and climate of Earth and Earth-like planets. In the past in my undergrad, I have used several 1-D numerical models to simulate planet structure and atmosphere. Currently, I am working on using 3-D chemistry-climate models (such as WACCM) to predict biosignatures from Earth analogues. In particular, I am investigating how their abundances and distributions may be shifted due to changes in stellar spectra and planetary rotation period. I hope my work will be able to inform current and future efforts to search for a second biosphere in the solar neighborhood.
