About me:

I am a Norwegian / British astronomer who working on the scientific preparation of the PLATO exoplanet mission. The PLATO space mission is designed to search for small, rocky exoplanets in the habitable zones of stars like the Sun.

I also work on a variety of astrophysical topics mainly focused on far-UV observations aimed at understanding the the formation environments of young planets. I am also very interested in work related to exoplanet atmospheres, radial velocity followup and the chemistry of exocomets.

I previously worked as a postdoc researcher at Leiden observatory in collaboration with Prof. Ignas Snellen. Prior to that I was working at the Institut d’Astrophysique de Paris where I mainly worked together with Dr. Alain Lecavelier des Etangs, Dr. Alfred Vidal-Majar and Dr. Guillaume Hébrard.

I obtained my PhD from the University of Exeter in 2014 with Prof. David Sing as my supervisor. Dissertation title: From Brown Dwarfs to Super-Earths: An Observational Study of Weather and Atmospheric Composition

My Research

Rarely in astrophysics do we have the opportunity to learn so much so fast about a new group of astrophysical objects such as exoplanets. Understanding their atmospheres is a necessary condition for learning more about the planets themselves, including formation, evolution, and (where relevant) habitability. To make sense of their atmospheres and formation history, we can look to the more easily observable brown dwarfs who partially overlap the exoplanetary parameter space with comparable radii, effective temperatures, composition and surface gravities. To gain insight into how they formed we can learn a lot by studying the chemistry and dynamics of their formation environments.

“I love outreach. It provides an excellent opportunity to showcase just how fascinating the Universe we live in really is.”

Through a programme called “meet the scientist”, I got the opportunity to travel around to schools and talk about astronomy. If you’d like me to visit your school, send me an email and then let’s see what we can arrange.

I have given a number of talks at astronomy clubs including Cape Town Obervatory, Norman Lockyer Observatory, Brannell Astronomy Society, Tavistock College
and Guernsey Astronomy Society.

If you’d like me to give a talk at your astronomy club, please send me an email.

I’ve given radio interviews, commented on astronomical events (online and in print) and provided background information to journalist. Please don’t hesitate to contact me if you’re from the media and you are looking for comments. I am fortunate to know people from within different fields of astronomy and I would be more than happy to refer you.
