I am interested in diverse topics in elementary physics, gravity wave physics, astrophysics/cosmology and QCD,. In realm of high energy physics I am concerned with using the data from the LHC to explain the origin of mass and the nature of the dark matter. I have worked on various topics in this field ranging from theories of extra dimensions to calculating Higgs boson production rates.  Recently, I have spent much of my time working on using ideas developed in quantum field theory to calculate classical gravity wave profiles for inspiralling black holes. Using these techniques we have been able to calculate the effects of black hole spin on the predicted wave forms which are hoped to be measured at the LISA experiment. I have also been working on effective field theory techniques to find systematic ways of calculating strong interaction observables at high energies.
