Sergei Katsev

Sergei Katsev is a Professor and Head of the Department of Physics & Astronomy at the University of Minnesota, Duluth. His research spans biogeochemistry and Earth sciences, focusing on elemental cycling in modern and ancient environments.

• Current Role: Professor & Department Head, Physics & Astronomy, University of Minnesota, Duluth
• Research Themes: Iron-sulfur-carbon cycles, ferruginous lakes, climate change impacts

His work integrates geochemical and biological processes to reconstruct Earth’s early environmental conditions and predict modern ecosystem responses to climate stress. Recent projects include NSF-funded studies on Lake Matano and Canyon Lake as analogues for early Earth oceans.

Article trends indicate a focus on isotope systematics, paleoenvironmental reconstruction, and climate-lake interactions, with significant contributions to understanding sulfur and uranium cycling in anoxic systems. Collaborations with institutions like Minnesota State University and National Science Foundation highlight his interdisciplinary approach.

Students and junior researchers benefit from his leadership in projects like NRT-IGE, which reimagines graduate curriculum to integrate environmental science and engineering. Media engagements, such as The battle for Lake Michigan (2020), underscore his societal impact.
