Research Interests

My main research interests are accretion inflows and outflows near compact astrophysical sources such as black holes (BH) and neutron stars (NS). Understanding the physical processes that lead to complex instabilities in these accretion flows is one of the most challenging and exciting fields in high energy astrophysics. More....

Teaching Interests

I've taught the following courses at Wheaton:

  • AST130 The Universe
  • AST202 Frontiers of Astronomy
  • AST302 Astrophysics
  • Other Interests

  • Having fun with the laws of physics.
  • Have I lost my coffee mug? It is a blue mug, with the upper and lower peninsula of the state of Michigan drawn on opposite sides. Here's a picture of the beloved mug.
  • Publications
