Jeff Zweerink

Jeff Zweerink (born January 1969; currently 57 years old) is an American astrophysicist, author, and research scholar known for his work bridging mainstream observational astrophysics and Christian apologetics. He earned his B.S. in physics and his Ph.D. in astrophysics from Iowa State University, where his research concentrated on high-energy gamma-ray astronomy exploring phenomena surrounding black holes and neutron stars. Zweerink has worked as an associate project scientist in the Department of Physics and Astronomy at the University of California, Los Angeles (UCLA), contributing to experimental particle astrophysics projects such as the General Antiparticle Spectrometer (GAPS) Antarctic balloon experiment aimed at detecting dark matter. Concurrently, he serves as a senior research scholar with the apologetics organization Reasons to Believe, where he writes and speaks extensively on cosmological topics—authoring works such as Who's Afraid of the Multiverse? and Is There Life Out There? to address scientific questions surrounding the big bang, fine-tuning, and extraterrestrial life from an old-earth creationist perspective.
