His main research concerns Combinatorics, Pure mathematics, Monic polynomial, Configuration space and Hausdorff dimension. The Combinatorics study combines topics in areas such as Structure, Type and Order. When carried out as part of a general Pure mathematics research project, his work on Riemann zeta function is frequently linked to work in Alternative hypothesis, therefore connecting diverse disciplines of study.

His Riemann zeta function research is multidisciplinary, relying on both Ergodic theory, Gamma function, Existential quantification and Counterexample. His research in Configuration space intersects with topics in Function, Motion, Radius and Factorization. Jeffrey C. Lagarias performs multidisciplinary study in the fields of Generic polynomial and Discrete mathematics via his papers.
