    My research focuses on the large distance modifications of general relativity (GR). The aim is to find a mathematically consistent theory of modified gravity that provides a 'natural' or 'mechanistic' explanation as an alternative to 'dark energy'. One of my focuses is a recently discovered field theory known as Galileon field theory. These are non-linear field theories with novel characteristics, both phenomenological and theoretical. Moreover these theories are extremely universal. They arise as effective field theories in seemingly different conceptual paradigms of modifying gravity such as brane world models and massive gravity.
