The root of the word sabbatical is “rest,” but Jan Tobochnik, physics and computer science, was in great demand as a lecturer during his sabbatical (June 2012 to March 2013). He gave five invited talks while on sabbatical. Three of the talks were titled “Network Analysis of Patent Citations,” and were based on work he did with fellow Kalamazoo College professor, Peter Erdi, physics and psychology, and others. These talks were given at Clark University, the Boston University Center for Computational Science, and the Northeastern University Center for Complex Networks Research. In addition, Tobochnik gave two talks titled “Physical Insight from Computational Algorithms,” at Universidad de Murcia in Murcia, Spain, and the University of Massachusetts in Dartmouth.
