Research

My research focuses on new methods to measure the impact of Dark Energy and Dark Matter from the closeby Universe. My research combines: Theory, Observational Data and Cosmological Simulations.

I have published over 70 articles in peer-reviewed international journals (e.g., PRD, A&A, ApJL), with more than 45 as first or single author. My publication record, over 4,000 citations, and an H-index of 26 reflect sustained creativity, scientific leadership, and independence.

Local Group Dynamics and the Dark Energy

My research uses our 'cosmic neighborhood' as a giant laboratory to study dark energy. We investigate the dynamics and movement of nearby galaxies, such as the Milky Way, Andromeda, and systems like Centaurus A and M81, to measure the impact of cosmic expansion. Projects in our group allow students to explore cutting-edge observational data and combine Data Science tools to better understand the mass and evolution of the local Universe.

Modified Gravity and the Nature of the Dark Universe

What makes up most of our Universe? We explore alternative models of gravity and attempt to unify our understanding of dark energy and dark matter. This research involves deep theoretical and analytical work, ranging from the two-body problem in astrophysics to our galaxy's environment, aiming to test the limits of fundamental physical theories against astronomical observations.
