Daniel John Kennefick

Daniel John Kennefick is a Professor in the Department of Physics within the College of Arts & Sciences at the University of Arkansas. His academic career uniquely bridges theoretical physics research and historical scholarship in general relativity and gravitational waves.

Dr. Kennefick's research focuses on gravitational waves, particularly from extreme-mass ratio black hole binaries relevant to the LISA space-based gravitational wave detector. He also conducts significant research in astrophysics, specifically on the density wave theory of spiral structure in disk galaxies. As a historian of science, he has established himself as an authority on the history of gravitational wave theory and eclipse expeditions testing general relativity.

His notable publications include Travelling at the Speed of Thought on the history of gravitational wave theory, No Shadow of a Doubt: The 1919 Eclipse That Confirmed Einstein's Theory of Relativity (Princeton University Press, 2019), and An Einstein Encyclopedia as co-author. His recent scholarly output (2022-2025) demonstrates a dual focus on gravitational wave detection concepts and historical analysis of relativity theory.

• Fellow of the American Physical Society
• Scientific editor for the Collected Papers of Albert Einstein (contributed to six published volumes)

Dr. Kennefick teaches across all university levels, from introductory to advanced graduate courses. His teaching specialties include gravitational physics, mechanics, astrophysics, and history of science. He regularly contributes to an interdisciplinary course on Charles Darwin and Evolution and mentors students through research supervision, special topics courses, and outreach activities including work with the Osher Lifelong Learning Institute.

His educational background includes bachelor's and master's degrees from the National University of Ireland and a PhD in Physics from the California Institute of Technology (Caltech). Prior to joining the University of Arkansas, he completed postdoctoral research at Cardiff University in Wales and at Caltech.
