I am an observational astronomer working to characterize exoplanets by studying their atmospheres. By using the Hubble Space Telescope and James Webb Space Telescope, I seek to understand the detailed atmospheric chemistry of gas giants, as well as predict which rocky planets are likely to have atmospheres. In the future, I also hope to examine rocky planets without atmospheres to place constraints on their surface composition. I have extensive data reduction experience, and I have also utilized open-source forward models and Bayesian retrievals. An exoplanet cannot be explored in isolation, however; we must also consider its stellar environment. For this, I have used telescopes at Apache Point Observatory to characterize the high-energy environment of a nearby host star; specifically, its flare rate and spectral energy distribution. I hope to continue to couple the study of exoplanets and their stars to map the complete picture of what nearby stellar systems are like and understand the prevalence of habitability in the Milky Way Galaxy.

I am a non-traditional student, having graduated with a B.S. in exercise science and worked in a cardiac rehabilitation clinic for several years prior to pursuing my first love of astronomy. I completed an M.A. in astronomy at Wesleyan University in 2022, which is a terminal degree program specifically designed for non-traditional students. There, I looked for signs of atmospheric escape on a hot Jupiter with Seth Redfield prior to joining David's Sing's exoplanets group here at JHU. I am elated to be joining the exoplanet community in a time of such rich discovery with JWST, and I look forward to all the science to come.
