I am an astrophysicist at the Max Planck Institute for Astronomy (MPIA) and am interested in exoplanetary atmospheres.   My work primarily involves using numerical and analytic models to understand the atmospheres of gaseous exoplanets.  Currently, I am working with Dr. Tom M. Evans-Soma, providing modelling to better understand JWST observations; however, I maintain an active collaboration with Prof Nathan Mayne and the Exoplanet Theory Group at the University of Exeter.
