Research

I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick. My supervisors are David Armstrong and Matteo Brogi. My research focuses on developing a novel method for measuring the amount of greenhouse gases in the Earth's atmosphere by using astronomical spectroscopic observations.

I got my MSc in Astronomy from Aarhus University, Denmark, where I was supervised by Simon Albrecht and worked alongside Emil Knudstrup. My thesis involved analysing the Rossiter-McLaughlin effect in selected systems and trying to obtain improved obliquity measurements by employing what is historically known as the Doppler tomography or Doppler shadow method.

Besides that, I'm also interested in detection and characterisation of exoplanets, the study of Solar System objects, climate science and astrobiology.

Outreach

• Planetarium manager (2023-present): I am one of the planetarium managers for the University of Warwick inflatable planetarium. We take the planetarium to primary schools to carry out shows for the children. On occasion, we also host visits to the University and the Marsh Observatory. As planetarium manager, I handle all of the administrative part, which includes processing schools' requests, gathering volunteers, sorting out transport of the equipment to the schools, and any other matter involving the planetarium.
• Coding with Sophie: volunteer for the Coding with Sophie project. Carried out 3 sessions at the Sidney Stringer Primary School.
• STEM partner for Tudor Grange Academy Redditch Weather Balloon project: acted as STEM partner for a Royal Society grant application to carry out a weather balloon project at the Tudor Grange Academy Redditch. Contact teacher at the school was Mr. Ben Wilkes.
• Big Bang Fair 2025: attended the Big Bang Fair 2025 as a volunteer for the University of Warwick Physics booth, specifically helping out the booth with the "superconductor train" experiment.
