My research focuses on stellar interactions and their astrophysical outcomes.
I have modelled the formation of interaction products of giant stars such as hot subdwarfs, RR Lyrae stars, stripped horisontal branch stars, and post-merger objects. My synthesised populations of these stellar types within the Galaxy show excellent agreement with available observational data.
On more compact scales, I have actively contributed to modeling gravitational wave sources from detached double white dwarf binaries, as well as white dwarf–neutron star and white dwarf–black hole binaries, synthesising detailed Galactic and extragalactic populations. Such binaries are critical sources anticipated for detection by the upcoming LISA and LGWA missions.
At even closer scales, my work includes modeling mass transfer onset and the resulting outcomes in double white dwarf systems, as well as white dwarf–neutron star and white dwarf–black hole binaries. These interactions produce diverse astrophysical phenomena, including thermonuclear transients, AM CVn binaries, ultracompact X-ray binaries (UCXBs), and peculiar transients similar to faing type Iax supernovae.
Additionally, I have explored stellar evolution within triple-star systems, focussing on eccentric mass transfer. I have also investigated stellar populations in star clusters and globular clusters, focusing particularly on runaway O- and B-type stars in star clusters and their interactions with ambient gas in globular clusters.
Overall, I believe significant, impactful science emerges at the intersection of well-established astrophysical topics. My research strategy revolves around exploring these intersections to effectively interpret observed stellar populations.
