Main projects

I am currently working on large scale simulations of the entire Solar convection zone. To achieve this we use the DISPATCH framework and the 'volleyball' mesh decomposition. We were awarded 165 million CPU hours from the EuroHPC Extreme Scale Access to run the simulations on LUMI supercomputer. I continue to work on improving the simulations and hope that soon we will be able to share some fantastic results with the scientific community.

Radial velocity in the Pilot simulation of the Solar convection zone

Academic interests

Solar physics, stellar and planetary atmospheres, magnetohydrodynamics, planet formation, radiative heat transport, plasma physics, statistical quantum mechanics

Background

I have obtained both my M.Sc. (thesis titled "Stellar model atmospheres of late spectral type stars") and Ph.D. (thesis titled "Planet formation. The roles of pebble accretion, radiative and convective energy transport") in the Niels Bohr Institute, University of Copenhagen in Denmark.  Apart of computational astrophysics, in my "free time", I like doing observational astronomy, I have participated in the MiNDSTEp collaboration, searching for exoplanets using the gravitational microlensing technique with the Danish 1.54m telescope in La Silla, Chile.
