Research Interests

• The origin/cause of the acceleration of the expansion of the Universe: Cosmological Constant, Dark Energy, Extensions to General Relativity.
• Testing gravity (General Relativity) at cosmological scales.
• Testing Dark Energy versus Modified Gravity at Cosmological Scales of Distance.
• Gravitational Lensing and applications to cosmology. Intrinsic Alignments of Galaxies.
• Constraining cosmological parameters and cosmological models using probes such as gravitational lensing, the cosmic microwave background (CMB), and supernova searches.
• Inhomogeneous Cosmological Models and the averaging problem in cosmology
• Selected topics in General Relativity and Exact Solutions to Einstein's Equations
• Projects at the intersection of modern cosmology and General Relativity
• Junction conditions for matching spacetimes and constructing wormholes and thin-shells
• Computer Algebra (symbolic computing) and application to cosmology and general relativity
