معرفی
Roman Holovchak is a Professor at the Department of Physics, Engineering and Astronomy of Austin Peay State University, specializing in materials science with focus on disordered solids and chalcogenide glasses. His work bridges structural characterization techniques like XPS, EXAFS, neutron scattering, and positron annihilation with applications in IR photonics, bioactive glasses, and radiation effects.
- Dr.Sc. (Habilitation) in Solid State Physics (2016, Vlokh Institute of Physical Optics)
- Ph.D. in Optics and Laser Physics (2004, Institute of Physical Optics, Lviv)
- B.Sc./M.Sc. in Physics & Electronics (1997, Ivan Franko National University of Lviv)
His research explores topological self-organization in glassy networks, relaxation phenomena, and photo-induced structural transformations. Key projects include radiation effects on materials, nanostructuring of non-oxide glasses, and development of bioactive glass scaffolds for biomedical use.
Recent publications analyze compositional effects in Ge-Ga-Se-Te systems, gamma-irradiation stability, and structural relaxation mechanisms. His work has been funded by the US National Science Foundation and US Department of Energy, with collaborations spanning Oak Ridge, Argonne, and Brookhaven National Labs.
Holovchak serves as a technical referee for major funding agencies and journals, contributing to 130+ peer-reviewed papers and 80+ conference works with an h-index of 22. His expertise includes thin film technology, optical spectroscopy, and materials for photonic devices.
