Research Description: I develop physically based mathematical theories of
gravitational lensing (light deflection by gravitational
fields) in a variety of astrophysical contexts and
investigate the observational consequences of the
associated theorems. I am currently researching flux
ratio anomalies with applications to the nature of dark
matter and exploring relativistic gravitational lensing
with applications to supermassive black holes. One of
my goals is to emphasize the stable and generic
features of lensing, drawing conclusions essentially
independent of the oversimplifying approximations of a
chosen lens system model. At the same time, I also
analyze in depth specific physically realistic models
having predictive power. The mathematical tools
employed draw upon the theory of singularities,
differential geometry, and probability theory. My
research involves collaborations with astrophysicists,
mathematicians, and physicists.
