About me

I am a postdoctoral fellow at the Max Planck Institute for Astronomy in Heidelberg. I obtained my PhD at Leiden Observatory under the supervision of Ignas Snellen. My research focuses on characterising the atmospheric chemistry of directly-imaged exoplanets and brown dwarfs.

To study these extrasolar atmospheres, I use spectroscopic observations both from space- and ground-based facilities. I try to understand how the observed spectra are affected by the physical and chemical processes taking place in the atmospheres. Additionally, I am interested in developing retrieval techniques to constrain the atmospheric properties.

An up-to-date overview of my publications can be found here. If you would like to get in contact, feel free to send me an e-mail at: deregt@mpia.de
