My primary research interests are in theoretical and high-energy astrophysics, including compact stars, radiative transfer and photon propagation in strong magnetic and gravitational fields, neutrino, plasma, and superfluid physics, accretion astrophysics, gravitational wave sources, magnetic field evolution, and stellar oscillations.
I am a Science Team member of NASA's Neutron Star Interior Composition ExploreR (NICER; see also here), Science Working Group member of ESA's Advanced Telescope for HighENergy Astrophysics (ATHENA), and Working Group member of the NewCompStar European COST Network. I am a member of the GEO Collaboration and Laser Interferometer Gravitational-Wave Observatory (LIGO) Scientific Collaboration. I am Southampton Mathematical Sciences' Square Kilometre Array (SKA) representative. I am a member of the American Astronomical Society and International Astronomical Union and Fellow of the Royal Astronomical Society and Higher Education Academy.
