Dr. Bruce Callen is chair of the physics department, and also serves as director of the Dual Degree (or 3-2) Engineering Program. He came to Drury in 1991, after three years of post-doctoral research at the University of Illinois at Urbana-Champaign, applying physics to the verification of international agreements limiting the underground testing of nuclear weapons. During his doctoral work, he studied high-energy collisions of light nuclei, looking for possible signs of the formation of a quark-gluon plasma. His teaching responsibilities include all undergraduate physics courses, Science & Inquiry, Undergraduate Research and Alpha Seminar. He has been a co-investigator on both of Drury's curriculum reform grants from the National Science Foundation, and is currently working on strengthening the connection between the science and the humanities. His research interests include digital astronomy, and reform in math and science and education.

Learn More About Dr. Hinrichs' Research

Dr. Brant Hinrichs spent several summers working on high-energy physics experiments at Brookhaven National Laboratory, where the asymmetrical scattering of polarized beam protons on a polarized proton target was investigated. Then, in 1987 it was on to the University of Illinois at Urbana-Champaign for Ph.D. studies in physics. His doctoral research used time series analysis on the signals recorded from the brain of an awake performing pigeon.

He spent two years in Tokyo, Japan as a research postdoc, returning to the states in 1997 to begin a teaching career. He got hooked on investigating how his students learned and didn't learn, and now, when time permits, does work in Physics Education Research, comparing how students learn and understand microscopic and macroscopic models of physics phenomena. He collaborates on this work with his colleague Dr. Beth Ann Thacker at Texas Tech. He currently is an Associate Professor at Drury, where he teaches the gamut from General Physics to senior-level quantum mechanics.

Professional Career Story of Dr. Gregory Ojakangas

Learn More about Dr. Ojakangas and his research in physics

Dr. Ojakangas' research has involved the orbital and volcanic histories of the moons of the solar system, the formation of the solar system, planetary ring dynamics, computer modeling of the human-made population of debris in orbit about the earth, and the rotational and orbital history of the earth-moon system as recorded in the geologic record. He was a finalist in NASA's astronaut selection program, he is an asteroid discoverer, and an inventor in the field of robotics. His current research involves computational neuroscience and brain-machine interfaces, and he is a consultant for NASA's orbital debris program. He also continues to lead groups of students in experiments aboard NASA's reduced gravity "Weightless Wonder" aircraft.
