Ioannis D. Spanopoulos, Ph.D is an Assistant Professor in the Department of Chemistry in the College of Arts and Sciences at the University of South Florida. He holds a BSc. degree in Chemistry and a MSc. degree in Environmental Chemistry and Technology from the National and Kapodistrian University of Athens. In 2015, he acquired his PhD. degree in Materials Chemistry from the University of Crete working on developing Metal-Organic Frameworks for gas storage and separation applications. In 2016, he joined the research group of Prof. Mercouri G. Kanatzidis at Northwestern University as a Post-Doctoral Fellow, focusing on the design and synthesis of environmentally friendly and stable perovskite materials for optoelectronic applications. He received the 2020 IIN Outstanding Researcher Award from the International Institute for Nanotechnology, the 2022 ACS PRF Doctoral New Investigator Research Award, and the 2024 DOE Early Career Research Program (ECRP) Award. He was recognized as an Emerging Investigator from the Journal of Materials Chemistry A, a Fellow of the International Association of Advanced Materials (IAAM), and a Highly Cited Researcher for the Year 2022. Research at the Spanopoulos Group focuses on utilizing molecular and crystal engineering to design and synthesize next-generation, multi-functional materials for energy and environment-related applications. The group recently reported two new families of materials, the Porous Metal Halide Semiconductors (PMHSs) and the crystalline Fullerene-based Metal Halide Semiconductors (FMHSs).
