His research is in Theoretical Particle Physics, and he works with experimental collaborations at Fermilab in Illinois, and CERN in Geneva, Switzerland. He is a member of the CTEQ collaboration—a novel collaboration of theorists and experimentalists. He co-authored the textbook Mathematica for Physics, which integrates new computer algebra programs into the core physics curriculum. The Mathematica notebook containing the examples and animations discussed in this review is available on the web at: http://www.physics.smu.edu/~olness/ftp/misc/math4, and the author can be reached at olness@mail.smu.edu.
