About me

I am an astrophysicist currently working as an Academy Research Fellow at the University of Helsinki (Finland), leading a project that connects plasma astrophysics and X-ray observations to constrain the physics of neutron stars.

My work is carried out in collaboration with the Plasma Astrophysics Group, led by Joonas Nättilä, and with the group of Anna Watts at the University of Amsterdam (The Netherlands), where I previously spent about three years as a postdoctoral researcher.

My research focuses on neutron stars—including their cores, atmospheres, and magnetospheres—using techniques such as X-ray pulse profile modeling and particle-in-cell simulations. I make extensive use of X-ray observations from instruments like NICER and IXPE.

I completed my PhD in 2020 at the University of Turku (Finland), in the High-Energy Astrophysics Group led by Juri Poutanen.

Research

My research focuses on topics in high-energy and plasma astrophysics, including neutron stars, magnetospheric return currents, X-ray pulse profile modeling, the equation of state of dense matter, neutron star atmospheres, radiative transfer, X-ray polarimetry, and accretion phenomena.

In my work, I use particle-in-cell simulations, high-performance computing, and statistical inference, and I develop computational tools in Python, Julia, Fortran, and C++.
