Dr. Mariia Fedkevych works in the field of experimental particle physics and astrophysics.  She received her doctoral degree from the University of Münster, Germany, in 2020 working on calibration and background reduction of KATRIN neutrino mass experiment. She was a postdoctoral researcher at the University of Genoa and National Institute for Nuclear Physics (INFN) section of Genoa in 2019-2022, Italy, working on isotope separation and ion implantation for the HOLMES neutrino mass experiment, and development of cryogenic detectors to study low-energy nuclear isomeric transition of Th-229m and Cryogenic Anti-Coincidence detector for X-ray Integral Field Unit of the ATHENA space observatory.

She joined the Department of Physics and Astronomy in 2022 to work with Prof. Ryan Wang on the operation and data analysis for the liquid scintillator-based outer detector of the LZ dark matter experiment and on developing the new type of veto system for generation 3 dark matter and neutrino experiments.
