Research summary
AI-generated

Ephraim Fischbach works in experimental and theoretical particle and nuclear physics, focusing on possible new fundamental forces beyond gravity and electromagnetism, anomalies in radioactive decay rates, and searches for connections between astrophysical events (like solar activity or neutron star mergers) and nuclear decay data. Much of the work involves re-examining precision measurements (such as tests of the equivalence principle and radioactive decay records) for subtle, unexplained patterns. This research is aimed at testing the foundations of fundamental physics using existing datasets and archival measurements.

Publication output has been fairly steady at a modest pace (roughly 3-7 papers/year) through 2023, but dropped sharply in 2024-2026 with only one or two outputs per year.
