A unifying theme of my research is the pursuit to connect fundamental physics with the cosmos. I am excited about multimessenger and gravitational-wave astronomy with Advanced LIGO and Virgo and its partner facilities in the electromagnetic band and the neutrino/high-energy particle sector. My research interests cover a broad range of topics including gravitational physics, nuclear astrophysics, high-energy astrophysics, and transient astronomy. Much of my research centers around unraveling the fundamental physics and astrophysics of compact binary mergers involving neutron stars and pertains to questions such as
- What are the physical processes that govern the dynamics of neutron star mergers and that give rise so observable electromagnetic radiation?
- How do such mergers and other astrophysical systems synthesize heavy elements in the Universe via the rapid neutron capture process (r-process)?
- What are the broader impacts on nuclear (astro-)physics and cosmology? What do such astrophysical phenomena tell us about how our Universe was chemically assembled?
In order to study these prime targets of multi-messenger astronomy, I perform fully general-relativistic magnetohydrodynamic simulations on supercomputers, including microphysical equations of state, weak interactions, neutrino radiation transport, and nuclear reaction networks, in combination with analytical and semi-analytical modeling. This allows me to obtain self-consistent predictions from first principles that can directly be compared to data from multi-messenger astronomy.
