My group's research centers around computational astrophysics, where we attempt to solve astronomical problems employing computational physics. These problems have consisted of many issues associated with the formation of solar systems and the orbital and rotational evolution of planetary satellites. Recently, we adapted our codes to study self-bound gravitating systems like stellar clusters and galaxies. Here, we are simulating the motion of stars in Dwarf Spheroidal Galaxies using an alternative to the dark matter paradigm, i.e. Modified Newtonian Dynamics (MOND).
