PhD in Astrophysics — Caltech
Dr. Marcus Webb earned his PhD in Astrophysics from the California Institute of Technology (Caltech), where his research centered on gravitational wave detection and the dynamics of compact stellar objects. After a decade in research, he transitioned to science communication, driven by the conviction that the most revolutionary ideas in physics — from curved spacetime to black holes — should be understandable to anyone willing to learn.
