Welcome to my academic webpage! As of January 2025, I am an ESA/AURA Astonomer I at the Space Telescope Science Institute in Baltimore, Maryland. In this position, 50% of my time is spent working as a member of the MIRI Instrument Team at STScI where I am working to support time-series observations (particuarly of exoplanets). This work also includes my role as the JWST Data Analysis Team Lead for the Rocky Worlds DDT Core Implementation Team, where I am leading a team of a dozen STScI staff to support the community in the analysis and interpretation of the MIRI eclipse observations that are being collected as a part of the Rocky Worlds DDT program. The other 50% of my time is spent doing independent research on the characterization of exoplanetary atmospheres and the development of new techniques to reduce and analyze time-series observations.

From September 2021 to January 2025, I was a BAERI Postdoctoral Research Scientist at NASA Ames where I was working with Thomas Greene and many others on JWST Guaranteed Time Observations with the MIRI and NIRCam instruments. My focus was on the optimal reduction and decorrelation of our team's observations to provide precise measurements of exoplanetary atmospheres with a focus on planets smaller and cooler than those typically observed by Hubble or Spitzer. I also co-led the publication of the MIRI/LRS phase curve of WASP-43b collected as a part of The JWST Transiting Exoplanet Community Early Release Science Program.

Previously, I was a Ph.D. student in the Department of Physics at McGill University. My supervisors were Nicolas Cowan from McGill University and Pierre Bastien from Université de Montréal. My Ph.D. research focused on the characterization of exoplanet atmospheres, with a focus on ultra-hot Jupiters. Throughout my degree, I made use of data from the Hubble Space Telescope and the Spitzer Space Telescope to study hot Jupiter atmospheres. I also dabbled with modelling the atmospheres of highly-irradiated exoplanets. One of my other projects used the newly comissioned POMM at the Observatoire du Mont-Mégantic to study the polarization of light reflected by known hot Jupiters.

NASA's JWST Maps Weather on Planet 280 Light‑Years Away

High temperatures and extreme wind speeds influence the chemistry of the planet's atmosphere.

An international team of astronomers used JWST to map the temperature and analyze the atmospheric composition around the hot Jupiter WASP‑43b. The results suggests that supersonic winds of hot gas are blowing around from the dayside, thoroughly churning up the atmosphere, and preventing the chemical reactions that would otherwise produce methane on the nightside.
