Research Interests

My work focuses on the application of ``Effective Field Theory” (EFT) to study complex, non-linear, strongly coupled systems. EFT is perhaps the most powerful tool we have to understand all aspects of science, as it is based upon the language of quantum field theory which is believed to correctly describe nature at all accessible distance scales. The EFT methodology can simplify complicated multi-scale problems by taking advantage of the deep and profound fact that nature allows us to separate physics at different distance scales. For instance, we can study a block sliding down a plane without knowing that the block is made of atoms. This ``decoupling” property is a consequence of a certain characteristic of all known physical laws known as ``locality”.

I have used EFT’s to study Higgs boson production at the LHC, the strong interaction dynamics of protons, cold atomic gases and black hole horizon physics. 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 being measured at the LIGO experiment. I have also been working on applying effective field theory techniques to novel quantum aspects of solids.
