Sergei Dubovsky

Sergei Dubovsky is a Professor of Physics at New York University, affiliated with the Department of Physics. His research focuses on theoretical particle physics, cosmology, and string theory, with particular interests in the physics of black holes, eternal inflation, and long-distance modifications of gravity. His recent work explores the cosmological and astrophysical signatures of axion-like particles, motivated by string theory, and investigates the potential of astrophysical black holes as tools for discovering such particles. Dubovsky's research has been published in leading journals and includes collaborations on topics such as string axiverse and causality in quantum field theory. He is based at 726 Broadway, Room 1057, New York, NY 10003, and can be contacted via email at sergei.dubovsky@gmail.com.

Sergei Dubovsky is a researcher at NYU whose work focuses on theoretical physics, particularly in the areas of string theory, cosmology, and quantum gravity. His research explores the implications of string axiverse, massive gravity, and the behavior of black holes in various contexts. Dubovsky investigates the interplay between causality, analyticity, and the infrared obstruction to ultraviolet completion, as well as the role of the null energy condition in superluminal propagation. His studies also include the analysis of cosmological models with massive matter and the use of astrophysical probes to test theories of unification. His work contributes to understanding the nature of dark matter and the constraints on millicharged particles from cosmic microwave background data.
