Science
My research in massive stars, supernovae and black holes.
Research Interests
My scientific interests concern the physical processes responsible for how stars evolve, die, and affect the Universe. I am a leader in the field of massive star evolution and supernovae, with unique expertise in theoretical and observational aspects of stars, atmospheres, and supernovae. The research of my group spans a large breadth of topics such as stellar evolution, stellar populations, supernova progenitors, luminous blue variables, and the nature of the first stars in the Universe. For addressing these scientific topics, I have developed unique numerical stellar evolution and radiative transfer models, in addition to leading and being involved in observational efforts to investigate stars and supernovae using major telescopes such as the Hubble and European Southern Observatory.
Publications
I have published 170+ scientific papers. Click below to see my full publication list at NASA/ADS and Google Scholar.
Presentations
I have given 40+ keynote talks for scientists at professional international conferences and in events for the general public.
Team Members
I was the founder and leader of the Massive Star Supernovae group at Trinity College Dublin, supervising a team of 4 PhD research candidates.
Conference Organization
I organized and facilitated 10+ international conferences on Astrophysics.
Professional Telescope Observations
I obtained competitive observing time in major facilities such as the Hubble Space Telescope and European Southern Observatory.
Advisory Boards and Commissions
I have served in several advisory and committee roles for funding agencies, grant evaluation, and telescope time allocation.
