Dr. Ali and Dr. Cleaver are The long-awaited CASPER video is now available in several formats for Newest to Baylor is Anzhong Wang who holds his doctorate from the attempting to find an M-theoretic formulation of the heterotic free informational and recruiting purposes. CASPER contracted with KWBU University of Ioannina in Greece. His extensive teaching and research fermionic string theory that Dr. Cleaver and his collaborators have to produce the digital promotional video with footage from all areas of experience includes appointments in Brazil, Greece and China. He is been working on for a number of years. currently working on three different research topics. Dr. Wang’s first Additionally, Dr. Ali is working on M-theory as it relates to the CASPER endeavor. The video was distributed to every high school area of interest concerns critical phenomena, the phenomena exhibited the seven manifolds of G2 holonomy.

Finally, Dr. Meihong Sun joins the CASPER faculty from Another area of interest for Dr. Wang is in brane-world scenarios. the Engineering department, where she is an Assistant Professor. She Brane-world scenarios were first proposed in 1998/99 and are designed received her Ph.D. from Northwestern University and her M.S. from Physics Circus T-Shirts on Sale to solve several outstanding problems, such as, the hierarchy and the University of Iowa.
