IUK Observatory: We have public nights at the observatory on the second Sunday of the month during the academic year.


Research Interests: I study compact objects through numerical simulations.  Compact objects are small, dense stellar remnants that if left on their own would be nearly invisible due to their small size  In many cases, however, these dead stars reveal themselves through interactions with their environment - often times though interacting with a partner star in a binary system.

Merger of two neutron stars
Merger of two identical neutron stars.  Vectors show magnetic field with amplitude in Gauss.

Neutron star black hole merger
Tidally disrupted neutron star accreting into a black hole.  The apparent horizon for the black hole is shown in black (duh) and magnetic field lines in the neutron star material are shown as stream lines.

double white dwarf merger
Temperature shown in color on a surface of constant density from a simulation of the merger of two white dwarf stars.  The temperature is in Kelvin.
