1. Was Einstein Wrong? : Theoretical and observational constraints on massive gravity
Abstract : For more than a century, Einstein's theory of general relativity has described gravitational phenomena with astonishing precision. However, for the theory to fit observations we need to add two elusive substances: dark energy and dark matter. Together they add up to 95% of the energy budget of the Universe. READ MORE

2. Gravitational collapse in bimetric gravity
Abstract : Einstein’s theory of general relativity has been the prevailing theory of classical gravity for over a century. Its observational consistency is unparalleled. There are however a few (arguably) serious shortcomings. READ MORE

3. Cosmic tests of massive gravity
Abstract : Massive gravity is an extension of general relativity where the graviton, which mediates gravitational interactions, has a nonvanishing mass. The first steps towards formulating a theory of massive gravity were made by Fierz and Pauli in 1939, but it took another 70 years until a consistent theory of massive gravity was written down.

4. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and PseudoGravity Gradient Tensors
Abstract : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. READ MORE

5. Stringed along or caught in a loop? : Philosophical reflections on modern quantum gravity research
Abstract : A number of philosophical questions, all connected to modern research in quantum gravity, are discussed in this dissertation.The goal of research in quantum gravity is to find a quantum theory for gravitation; the other fundamental forces are already understood in terms of quantum physics.
