Personal profile
Research interests
I am a theoretical astrophysicist expert in modelling the formation and co-evolution of stars, galaxies and cosmic structures. I makes use of the biggest supercomputers to undertake extremely detailed fluid dynamics models of galaxies, aiming to answer questions such as "what is the nature of dark matter?", "how and where did the first stars formed?", or "how did the chemical elements like carbon and oxygen came to permeate our Universe?".
Teaching interests
I am currenlty teaching astrophysics courses, data analysis and computer science for physics.
Willing to supervise doctoral students
I am currently looking for a PhD student and open to future MPhys projects. Do get in touch if you are interested.
