Marko E. Popović is a Senior Research Associate at the Institute of Chemistry, Technology and Metallurgy, University of Belgrade. From 2019 to 2022, he worked as a researcher at the School of Life Sciences, Technical University of Munich. From 2021 to 2022, he worked as a lecturer at EuroTeQ Engineering University. Since April 2023, he has worked as a researcher at the University of Belgrade. In October 2023 and September 2024, he was included in the prestigious World Ranking of Top 2% Scientists, made at Stanford University. The fields of research of Marko E. Popović are the thermodynamic and bioenergetic characterization of live matter and biological processes. He worked on the characterization of microorganism live matter (bacteria, fungi, algae, viruses), with applications in bioprocess design and sustainable production. He also worked on the influence of energy on interactions between organisms, including virus/host, bacteria/host, and fungi/host interactions, as well as interactions of organisms in the environment. He was the first to publish the empirical formula and standard thermodynamic properties of SARS-CoV-2, SARS, MERS, Ebola, Mpox, West Nile virus, Rotavirus A, Herpes simplex type 1, HIV-1, bacteriophages, and other viruses, as well as viroids. He was the first to chemically and thermodynamically characterize over 35 species of bacteria, fungi, and algae.
