Our current research interest includes

• Astrophysics of Exoplanets: dynamics, formation, protoplanetary disks, star-planet interactions, etc
• Compact Objects: neutron stars, black holes, white dwarfs; gravitational wave sources, radiative processes, condensed matter, neutrinos, etc
• Astrophysical (particle and fluid) dynamics in general: celestial mechanics, waves, oscillations, instabilities, etc
