Profile

Currently, I am a Teaching Associate and Digital Skills Lead in the School of Chemical, Materials and Biological Engineering. My research interests are related to the study of the birth, life and death of the most massive stars in the universe. Massive stars are key to our understanding of galaxy evolution and the chemical enrichment of the Universe which are the building blocks of planets and life as we know it today. With their strong outflows and high ionising fluxes they dominate the evolution of galaxies and are thought to have played a crucial role in providing ionizing radiation, mechanical and chemical feedback in galaxies in the early the Universe.

Career history:

PDRA in the astrophysics group of Prof. Dr. Paul Crowther at the University of Sheffield (2017-2024).
PDRA in the stellar spectroscopy and populations group of Dr. Maria Bergemann at the Max Planck Institute for Astronomy (2015-2017).
PDRA in the stellar physics group of Prof. Dr. Norbert Langer at the Argelander Institute for Astronomy (2014-2015).

Education:

PhD in Astrophysics from the Queen's University Belfast with Prof. Dr. Jorick Vink at the Armagh Observatory.
Graduate Physicist at the Ruprecht-Karls-University Heidelberg with Diploma thesis at the Max Planck Institute for Astronomy under the supervision of Dr. Dimitrios Gouliermis.

Research interests: My research is centred on the massive star population of the Milky Way and Magellanic Clouds, which are a pair of interacting galaxies on its first encounter with the Milky Way. The aim is to study the physical, evolutionary and stellar wind properties of massive stars, because they are key to our understanding of galaxy evolution and the chemical enrichment of the Universe which are the building blocks of planets and life as we know it today. With their strong outflows and high ionising fluxes they dominate the evolution of star-forming galaxies and are thought to have played a crucial role in providing ionizing radiation, mechanical and chemical feedback in galaxies in the early the Universe.
