Professor Nico Yunes received his bachelor's degree from Washington University in Saint Louis in 2003, and his Ph.D. from The Pennsylvania State University in 2008. After a Research Associate position at Princeton University and an Einstein Fellowship at MIT and Harvard, he joined the faculty at Montana State University (2011-2019) and then accepted a faculty position at the University of Illinois in 2019. He is also the founding director of the Illinois Center for Advanced Studies of the Universe.
Professor Yunes is a theoretical physicist that specializes in general relativity and gravitation. He has an international reputation for his work on tests of General Relativity with gravitational waves, universal relations in neutron stars, and black holes in theories beyond Einstein's. He is one of the creators of the parameterized post-Einsteinian framework to test Einstein's theory in a model-independent way with gravitational waves. Professor Yunes is also one of the discoverers of the the I-Love-Q and the Binary Love universal relations of neutron stars, which are used by the LIGO scientific collaboration to infer the equation of state of matter at extreme densities.
His research focuses sharply on the study of extreme gravitational phenomena that may reveal solutions to puzzles in fundamental physics, such as the late-time acceleration of the universe, the nature of dark matter, the baryogenesis problem, and the unification of quantum mechanics and general relativity. Departures from paradigms, or "anomalies" in the data, tell us that there is still much we do not know about the universe, and thus, much to learn. Hints toward an explanation for such anomalies may arise from extreme gravity observations, a regime where the gravitational force is simultaneously unfathomably large and violently changing, a regime that in fact we are only now beginning to probe with gravitational waves. The probing of this regime may provide important hints to the answer of common questions, such as, why is there more matter than antimatter in the universe? What is the true nature of dark matter? What is causing the universe to accelerate in its expansion at the measured rate? Understanding the physics and modeling the observables in this extreme gravity regime is Prof. Yunes' primary focus.

Professor Yunes and his research group study extreme gravity, from the physics of binary pulsars to the gravitational waves emitted in the coalescence of black holes and neutron stars. Observations in the extreme gravity regime may provide hints toward the resolution of outstanding problems in fundamental physics, such as those associated with dark matter, dark energy, the physics of the early universe and quantum gravity. His group uses analytical and semi-analytical techniques rooted in perturbation theory and multiple scale analysis to predict the signatures that potential solutions to these problems would have on observables. His group then uses frequentists and Bayesian data analysis techniques to search for these signatures and constrain their existence in data, thus informing model building in high-energy theory, cosmology and nuclear theory.
