## Summary

My expertise lies at the interface between particle physics, gravity and cosmology where I develop and test new models and paradigms.

**Understanding Gravity at the Fundamental level**:

Understanding gravity with an emphasis on theoretical consistency, quantum stability and relevance for cosmology.**Tests of Gravity**: Using Gravitational Waves to probe gravity in conjunction with laboratory, Solar System, Astrophysical Cosmological tests and screening mechanisms. **Early Universe Cosmology: **Probing signatures of the Early Universe be it for inflation or its alternatives.

**What is the source of the late–time acceleration of the Universe ?**

**Dark Energy**:**Understanding the effect from vacuum energy of particle physics on cosmological scales.**

**Cosmological Constant Problem**:**Understanding the low-energy restrictions to the existence of a standard high energy completion and consequences to Cosmology and Particle Physics.**

**UV Completeness**:See inSpires for a list of publications
