Rate My Professor Andrey Semichaevsky

Andrey Semichaevsky is an Associate Professor in the Department of Chemistry and Physics at Lincoln University, Pennsylvania, where he also coordinates the engineering and physics programs. Holding a Doctor of Engineering from the University of Massachusetts at Lowell, he joined Lincoln University around 2015 as an Assistant Professor, earning tenure and promotion to Associate Professor in 2018. Previously, he was a postdoctoral researcher at North Carolina State University’s AIMS Laboratory from 2007 to 2008, the University of Illinois at Urbana-Champaign’s Johnson Research Group, and conducted doctoral research in electrical and computer engineering at UMass Lowell. Semichaevsky serves on the Faculty Council and has led initiatives such as NSF-supported undergraduate electrical engineering research and Lincoln University’s participation in the 2023 NASA Nationwide Eclipse Ballooning Project.

His academic interests center on computational physics and materials science, particularly developing ab initio methods using Green’s functions to predict molecular optical properties and excited states, overcoming limitations of density functional theory. Funded by a 2020-2021 Faculty Development Grant, this work involved XSEDE supercomputers, Monte Carlo integrations, and parallel computing. Earlier research encompasses first-principles optical property calculations for MgB₂ and SiC (2006-2008), metamaterial-loaded planar antennas, phase-space tomography for phase retrieval, and photovoltaic studies including carrier transport in polycrystalline silicon at high injection levels and temperature-induced degradation of solar cell efficiency. Key publications feature “Phase retrieval and phase-space tomography from incomplete data sets” (2004), “First-principles studies of the optical properties of MgB₂: computational vs. experimental results” (2007), “Carrier transport in polycrystalline silicon at high optical injection” (2018), and presentations on minority carrier trapping in silicon at WCPEC-7 (2018). Semichaevsky has contributed to conferences such as APS March Meetings, IEEE PVSC, and URSI.
