Chris McMullen is a physics instructor at Northwestern State University of Louisiana. He earned his Ph.D. in phenomenological high-energy physics (particle physics) from Oklahoma State University in 2002. Originally from California, he earned his Master's degree from California State University, Northridge, where his thesis was in the field of electron spin resonance. He has published several papers on the prospects for discovering large superstring-inspired extra dimensions at the Large Hadron Collider. Dr. McMullen has taught first- and second-semester physics labs, at the trig-based and calculus-based level, at four different universities using a wide variety of equipment, sensors and computer interfaces, and software programs. He has authored the laboratory manual for NSULA and LSMSA, and has involved several students with research projects as part of their first-year physics lab.
