Jeff Zweerink

Astrophysicist Jeff Zweerink is a research scholar for Reasons to Believe (RTB), an organization dedicated to demonstrating the compatibility of science and the Christian faith. Jeff’s work focuses on helping people of all backgrounds bridge the perceived gap between science and the Christian faith.

Jeff has also made many media appearances, on television, radio, and in print. He earned a BS in physics and a PhD in astrophysics with a focus on gamma rays from Iowa State University. He taught and ran the planetarium at Loras College in Dubuque, Iowa, until postdoctoral research in gamma rays led him to the University of California, Riverside.

Prior to joining RTB, Jeff spent years working on the STACEE and VERITAS gamma-ray telescopes and was involved in research projects such as the Solar Two project and the Whipple Collaboration. He continues to work as a project scientist at UCLA on GAPS, a balloon experiment seeking to detect dark matter. Jeff is also a coauthor on more than 30 academic papers published in peer-reviewed journals, such as Astrophysical Journal, Astroparticle Physics, and Astrobiology.

A Christian from childhood, Jeff struggled to reconcile his love of science and his desire to serve God. While an undergrad at Iowa State University, he heard astrophysicist and RTB founder Hugh Ross speak on the constructive integration of science and faith. Hugh’s old-earth perspective introduced Jeff to a creation view that aligns with both Scripture and science. Ten years later, a professor encouraged Jeff to enroll in RTB’s volunteer apologetics program. This involvement eventually led to a scholar position in 2005.

Today, Jeff writes and speaks on the compatibility of science and the Christian faith and on evidence for intentional design from a multiverse theory, dark energy and dark matter, and exoplanets. His speaking engagements take him to universities, churches, and other venues around the world, including high schools and youth groups and numerous conference proceedings. He is also the author of Is There Life Out There?, Who’s Afraid of the Multiverse?, and Escaping the Beginning?.

Jeff and his wife, Lisa, live in Southern California and have five children.
