Experience
Cleaver is Professor of Physics and Graduate Program Director in the Department of Physics at Baylor University. He is a member of the High Energy Physics group and heads the Early Universe Cosmology and String Theory (EUCOS) division of Baylor’s Center for Astrophysics, Space Physics, and Engineering Research. Gerald earned his Ph.D. at Caltech in 1993, where he studied under John H. Schwarz, one of the founders of string theory. Cleaver has written over 85 peer-reviewed journal papers and conference proceedings, which have received over 1300 total citations. He is author of four book chapters, author of an encyclopedia entry, and co-author of one text book.
Research Interests
Cleaver's primary research interests are string/M Theory, quantum gravity, and early universe cosmology. EUCOS conductslong-term systematic studies of the global properties of the string landscape in the free-fermionic heterotic region and more general issues of a string/M multiverse. (On the side, Cleaver frequently writes about philosophical implications of a multiverse.) Cleaver, Physics colleague Anzhong Wang, Baylor Math faculty Klaus Kirsten and Qin Sheng, and joint postdoc Tao Zhu investigate aspects of Horava-Lifshitz theory and trans-Planckian physics of the very early universe. With EUCOS Adjunct Researcher Jeffrey Lee in Toronto, Cleaver investigates thermodynamical aspects of special relativity. With colleagues in Icarus Interstellar (founded by Cleaver's Ph.D. graduate Richard Obousy), Cleaver also also studies advanced propulsion systems for spacecraft and was recently appointed to a blue ribbon review panel for NASA-Johson Space Center.
