About

Dr. Gerald B. Cleaver is a highly skilled and experienced problem solver. He especially enjoys projects simultaneously requiring large- and small-scale analysis, wherein logic meets creativity, and abstract thinking is applied to real-world situations. Cleaver is a dedicated leader with over 22 years of management experience of research groups, and is an eloquent communicator with more than 24 years of teaching experience. He directs the Early Universe Cosmology and Strings (EUCOS) division of Baylor University's Center for Astrophysics, Space Physics, and Engineering Research (CASPER) and has advised the dissertation research of 20 M.S. & Ph.D. students (13 graduated, 8 current). During his 2013 to 2022 tenure as Physics Graduate Program Director, Cleaver coordinated the graduate programs of over 100 students and managed the \~ $700K teaching assistantship budgets. Working with faculty colleagues, he doubled the physics graduate student enrollment from 25 in 2013 to the present 52. Cleaver was written over 85 peer-reviewed research journal articles and 25 conference proceedings. He has spoken at more than 70 conferences and workshops. Cleaver is co-author of one physics textbook and has authored six book chapters and an encyclopedia entry.
