Chloe Fisher

Dr. Chloe Fisher is a Research Fellow at the University of Oxford and a Junior Research Fellow at Brasenose College. She holds a PhD in exoplanet atmospheres from the University of Bern, Switzerland, and is a recipient of the Swiss National Science Foundation Postdoctoral Mobility Fellowship. Her research focuses on characterizing exoplanet atmospheres using machine learning and Bayesian inference, particularly leveraging data from the James Webb Space Telescope (JWST).

Educational Background:

• BA & MSci (Mathematics/Astrophysics) - University of Cambridge
• PhD in Exoplanet Atmospheres - University of Bern

Research Interests: Exoplanet atmosphere modeling, atmospheric retrieval methods, machine learning applications in astrophysics, JWST observational strategies, and Bayesian statistical techniques.

Key Projects:

• Principal Investigator (PI) of two JWST Cycle 2 programs targeting super-Earths and sub-Neptunes (TOI-1685 b, TOI-125 b/c).
• Co-Investigator (Co-I) on the Hot Rocks Survey (PI: Hannah Diamond-Lower), studying rocky exoplanets.
• Leading studies comparing JWST/NIRISS and HST/WFC3 capabilities for exoplanet characterization.

Awards:

• Swiss National Science Foundation Postdoctoral Mobility Fellowship (SNF).

Grants & Collaborations:

• PI of JWST observational programs (IDs 4126, 4195).
• Contributions to open-source tools like the HELIOS-K opacity calculator.

Labs/Teams: Part of the Department of Physics' Astrophysics subgroup at Oxford, collaborating with international teams on exoplanet data analysis.
