Research

My research focuses on exploring the space of alternative theories of gravity. I approach this work from the premise that general relativity is incomplete as a theory of gravitation, and seek to identify, develop, and test possible extensions and modifications of the theory. These include, but are not limited to, scalar-tensor theories, vector-tensor theories, massive gravity, metric-affine gravity, and f(R) gravity. My research combines theoretical and computational techniques, including analytical methods, numerical simulations, and machine learning, to investigate the foundations and phenomenology of modified theories of gravity.
