My expertise lies at the interface between particle physics, gravity and cosmology where I develop and test new models and paradigms.
Early Universe Cosmology: Probing signatures of the Early Universe be it for inflation or its alternatives.
Dark Energy: What is the source of the late–time acceleration of the Universe ?
Cosmological Constant Problem: Understanding the effect from vacuum energy of particle physics on cosmological scales.
Behaviour of Gravity: Deriving alternatives to General Relativity with an emphasize on theoretical consistency and quantum stability.
Tests of Gravity: Gravitational Waves, Lab, Solar System, Astrophysical and Cosmological signatures and tests of Gravity and screening mechanisms.
UV Completeness: Understanding the low-energy restrictions to the existence of a standard high energy completion and consequences to Cosmology and Particle Physics.
