Lance Seefeldt serves as Professor and Department Head in the Department of Chemistry and Biochemistry within Utah State University's College of Arts & Sciences. His research focuses on the biochemical mechanisms of nitrogenase enzymes, which catalyze biological nitrogen fixation essential for global nutrient cycles.
His work spans biochemistry, enzymology, and bioinorganic chemistry with emphasis on nitrogenase kinetics, metallocluster dynamics, and evolutionary adaptation. Key research areas include ATP-dependent catalysis, substrate reduction pathways, and spectroscopic characterization of reaction intermediates using EPR, ENDOR, and voltammetric techniques. His group pioneers biohybrid systems combining nitrogenase with nanomaterials like CdS quantum dots for photochemical nitrogen fixation.
Analysis of his 2023-2025 publications reveals dominant themes: (1) Evolutionary reconstruction of ancient nitrogenases across geological time, (2) Mechanistic studies of ATP dependence and N2 reduction intermediates, (3) Development of nanomaterial-enzyme biohybrids for sustainable ammonia production. These investigations bridge fundamental enzymology with applications in sustainable agriculture and space exploration life-support systems.
As Department Head, Dr. Seefeldt maintains active research leadership while overseeing academic operations. His extensive publication record demonstrates sustained productivity in nitrogenase research, though specific student mentorship details and awards are not documented in the provided materials.
