Biography

Born in Ukraine and raised along the stunning northern coast of Lake Baikal in Siberia, she grew up inspired by nature and the arts, with a love for painting, literature, and mathematics. Her interest in the universe brought her back to Ukraine, where she began studying gravitational physics, and later to the Czech Republic, where she continued research on black holes and cosmology. She is now a Visiting Research Scientist in the Department of Physics at the University of Illinois Urbana-Champaign. Her work focuses on exact solutions in general relativity, including models of black holes embedded in cosmological media, the interplay between cosmological expansion and local gravity, perturbations of cosmological black holes, and superradiance.

Though 14,000 kilometers from Baikal to Illinois is modest by cosmological standards, it has been a rewarding path, and it continues.
