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.
