Dissertation Title: Peculiar perovskites: Unraveling the unique optical response of hybrid organic-inorganic perovskites from first principles
Contact information: leveill2@illinois.edu
Research Interest: My research interests focus on using first principles computational methods, mainly density functional theory, to analyze the behavior of materials on the electronic/atomic level. The work involves implementing modern theory to address computational challenges in modeling organic-non organic hybrid electron materials. This research aims to positively impact the efficiency and safety of new materials for energy applications.
