Dr. Sergey Kosourov began his research career in 1998 as a junior researcher at the Institute of Basic Biological Problems, RAS, where he joined the Laboratory of Biochemistry and Biotechnology of Phototrophic Microorganisms. In 2000, he earned a Ph.D. in plant physiology from Moscow State University. Sergey then undertook two assignments at the National Renewable Energy Laboratory (NREL), DOE, U.S.: first as a postdoctoral fellow (2002–2003) and later as a research associate (2006–2009). Between and after these assignments, he worked as a senior and, subsequently, a leading researcher at the Institute of Basic Biological Problems, RAS. In 2013, he joined the Molecular Plant Biology team at the University of Turku.

Dr. Kosourov has co-authored 43 research papers and six book chapters in the fields of solar chemical and fuel production, whole-cell thin-layer immobilization, and solid-state photosynthetic cell factories. Additionally, he holds an international patent for the design of a multi-stage photobioreactor system for H2 production.
