Prof. Kearfott's research interests are clustered in several areas. These include global optimization, software development and computer arithmetic, interval computations, and modeling associated with operations research problems. Specifically, one aspect of his work focuses on branch and bound algorithms for continuous global optimization, with an emphasis on accounting for roundoff error to obtain mathematically rigorous bounds. This work has grown out of an interest to understand nonlinear systems, including parametrized systems and singularities. In the operations research line, Prof. Kearfott has collaborated with the Center for Business Information Technology and a graduate student to develop a model, specific to Lafayette Parish, for pre-placement of post-emergency relief supplies; that project led the student and Prof. Kearfott to develop an extensive knowledge of transportation and facility location models.

Prof. Kearfott has a single-authored monograph, has co-authored two other books, and has edited three collections of work appearing as books. Among many papers, he has published various articles in the ACM Transactions on Mathematical Software, the SIAM journal on Numerical Analysis, the SIAM journal on Scientific Computing, the Journal of Global Optimization, and Optimization Methods and Software, he is on the editorial board of Optimization Letters, and he is the managing editor of Reliable Computing. He has been active in producing an IEEE standard for interval arithmetic, and he is presently chair of the IEEE Standards Association Microprocessing Standardization Committee.
