Ephraim Fischbach

Ephraim Fischbach is a Professor of Physics at Purdue University since 1979, with academic roles spanning from Assistant Professor (1970-74) to current full Professor. He holds a B.A. in Physics from Columbia University (1963), M.S. (1964), and Ph.D. (1967) from the University of Pennsylvania. His research focuses on gravitational physics, nuclear decay anomalies, and solar influences, with notable work on the connection between precision gravity experiments and high-energy physics.

Key research areas include testing gravitational theories, fifth-force searches, and analyzing time-dependent nuclear decay rates linked to solar activity. He has advised over 20 graduate students, contributing to advancements in experimental physics and theoretical models. His 2001 American Physical Society Fellowship recognizes his contributions to understanding gravity and particle physics intersections. Fischbach has collaborated on groundbreaking experiments like the Casimir force measurements and the Solar Influence on Decay Rate (SIDR) project.

• Education: Columbia University (B.A., 1963), University of Pennsylvania (M.S. 1964, Ph.D. 1967)
• Professional Activities: APS Fellow, consultant for Particle Data Group, and departmental roles in outreach and student disability support.
• Key Publications: Over 100 peer-reviewed articles, including landmark studies on decay-rate fluctuations and gravitational anomalies.
