Lance C. Seefeldt mostly deals with Nitrogenase, Biochemistry, Catalysis, Stereochemistry and Active site. His studies in Nitrogenase integrate themes in fields like Inorganic chemistry, Molecule, Substrate and Electron transfer. Lance C. Seefeldt has included themes like Molybdenum and Acetylene in his Catalysis study.

The Stereochemistry study combines topics in areas such as Hydrogenase mimic, Hydrogenase, Crystal structure and Ammonia. The study incorporates disciplines such as Crystallography, Electron paramagnetic resonance and Cofactor in addition to Active site. In his work, Fatty alcohol is strongly intertwined with Enzyme, which is a subfield of Nitrogen fixation.
