A native New Englander, Rich graduated from Boston College and received his Ph.D. from Indiana University. During 1984-86 he worked on an intelligent geometry tutor in the artificial intelligence research group at IRISA in Rennes, France. His professional interests subsequently expanded to include use of computer geometry systems in schools both in this country and in France. During 1991-92 and again during 1998-99, he returned to France, to IMAG in Grenoble, to continues his research collaboration on intelligent geometry systems and to participate in interdisciplinary research on the cognitive effects of the use of such systems. His interests have further evolved to include the geometry of Islamic patterns and bioinformatics.His wife, Wendy, is professor of French at St. Olaf. His son, Joshua, and his daughter, Sarah, both graduated from another Northfield college. Rich and Wendy led the Term in the Middle East in 2001-02 and the Global Semester in 2005-06 and again in 2008-09.

Adam arrived at St. Olaf in 2009, having received his Ph.D. in 2009 from the University of Wisconsin - Madison. He is no stranger to Northfield, however, as he earned his B.A. from another Northfield liberal arts school in 2002. Adam's academic interests are in combinatorial matrix theory, linear algebra, graph theory, and issues in undergraduate mathematics education. Despite his time in Wisconsin, Adam remains an avid Twins and Vikings Fan. In his spare time, Adam enjoys tennis, swimming, cooking & baking, and watching reality television (especially Survivor).

Ian is new to St. Olaf College, having recently completed his Ph.D. in Lincoln, Nebraska. He grew up in north central Massachusetts. After a couple of false starts, some K-12 teaching, and two interruptions for military service, his academic pursuits ultimately brought him to the midwest. His mathematical research interests are broadly concerned with analysis. Ian enjoys cooking, reading anything he can get his hands on, and being outdoors (he sorely misses living near mountains and forests). His two young children (ages 3 years and 3 months) occupy most of his non-working hours and help to keep him out of (or get him into) trouble.

Paul is an applied statistician, having attacked problems ranging from clinical trials in panic disorder to population models for bowhead whales to indicators of welfare recidivism to the effects of forest fragmentation on birds. He returns to The Hill after a long hiatus; after graduating from St. Olaf in 1989 with majors in mathematics and economics, Paul earned an M.S. in statistics from Iowa State, worked as a clinical statistician for Eli Lilly, earned a Ph.D. in statistics from Colorado State, and taught for several years at both Bucknell and Connecticut College. In addition to applied statistical consulting, Paul's research interests include Bayesian statistics, nonparametric methods, and statistical education. Paul and his wife Karen have three young children--Samantha, Timothy, and Sophie--who keep his office decorated with fine artwork. Outside of his office, Paul can often be found on some athletic court or field, playing basketball, tennis, soccer, and maybe even broomball. Or, he can be found putting his statistical knowledge to good use--attempting to win the coveted Joe Boe Trophy in the Boe Fantasy Football League. (2004)

Paul's life began in southern India, near the confluence of the Bay of Bengal, the Arabian Sea, and the Indian Ocean. He was educated through high school at Kodaikanal International School, high in the cool, green Palni Hills in the South Indian state of Tamilnadu (formerly Madras). He was an undergraduate at Washington University in St. Louis, majoring in mathematics and English literature. He did his Ph.D., in several complex variables, at the University of Washington, Seattle, and came to St. Olaf in 1981. His professional interests include complex analysis, mathematical exposition, and textbook writing. During 1995-2000 he was Editor of Mathematics Magazine. In 2011 and 2012 he will serve as President of the Mathematical Association of America. Paul and his wife, Janet, an occupational therapist, have two grown daughters, Anne and Elizabeth. Both are named for Austen heroines, and both graduated from (other) liberal arts colleges.
