 Full-Time Faculty
 

Doug Cashing received a bachelor's degree in mathematics/secondary education in 1971 and a master's degree in mathematics in 1973 from SUNY Oswego. Dr. Cashing obtained a Ph.D. in mathematics education from Syracuse University in 1979. After teaching at St. Francis College in Loretta, Pennsylvania for two years, he joined the Mathematics/Computer Science Department at St. Bonaventure. He taught courses in both mathematics and computer science until 1992, when the two programs separated.

Dr. Cashing is the coordinator for our two regional mathematics contests: MATHCOUNTS and The Challenge 24 Competition. He has written a file processing textbook and eight articles that have been published in professional journals, and he has presented talks at several professional conferences. He has been actively involved with the grading process for the Advanced Placement Statistics Program since the first exam was given in 1997 and has presented numerous workshops for high school AP Stats teachers since the fall of 1998. He enjoys skiing, sailing, and classical music.

Maureen P. Cox received a B.S. in physics from Rensselaer Polytechnic Institute, a M.S.T. in mathematics from Boston College, and a Ph.D. in mathematics from the State University of New York at Albany. She joined the faculty at St. Bonaventure in 1996. She has been active in incorporating the use of technology in calculus and differential equations courses. She has also been teaching in the HEOP Summer Challenge Program since 2002.  Her thesis work was in Hopf Galois theory. She has coauthored two papers on mathematics education: “How Long is the Train in View,” in the New York State Mathematics Teachers' Journal; and “An Application of the Inverse Sine and Cosine Functions,” in Mathematics and Computer Education.  Dr. Cox currently has a paper in preparation on mathematical thinking in ancient Ireland. Her interests outside the classroom include music, quilting, gardening, sailing, and yoga. Dr. Cox is currently the chair of the Mathematics Department.

Dr. Cox researched the mathematics of ancient Ireland during her 2004 sabbatical project. Part of her research was conducted in Ireland. Photographs from Dr. Cox's trip, such as the one to the left of 5000-year-old stone etchings at Newgrange, may be viewed here.

Chris Hill received a B.S. in mathematics with a minor in physics and an M.S. in mathematics from Colorado State University. He studied at the University of Illinois at Champaign-Urbana for his Ph.D. in mathematics. Prior to joining the faculty at St. Bonaventure in 2003, Dr. Hill taught at Grinnell College in Grinnell, Iowa and at Furman University in Greenville, South Carolina.  In the classroom, Dr. Hill is deeply interested in non-traditional methods of teaching, that is, methods of teaching other than lecture-discussion. His research interests lie in analytic number theory. Dr. Hill runs the Bona's Bonus Problems program, supervises the Putnam Exam, and organizes (along with Dr. Chris Leary) the SBU Student Chapter of the Mathematical Association of America. He taught in the HEOP Summer Challenge Program in 2006. His interests outside the classroom include cinema, juggling, classical music, and wallyball (a cross between volleyball and racquetball).

Michael Klucznik earned a B.A. (1982) in biology and an M.S. (1988) in medical sciences from Harvard University and finally a Ph.D. (1996) in Mathematics from Brandeis University. He joined the faculty of St. Bonaventure in 2005. Dr. Klucznik researches in representation theory and algebraic applications to biology and physics. Amongst his publications are “2kn-Binomial(2k+1,2)” (joint with Andreas Dress, Jack Koolen, and Vince Moulton) in Séminaire Lotharingien de Combinatoire and “Parabolic Decomposition of Properly Stratified Algebras” (joint with Vlodomir Mazorchuk) in the Journal of Pure and Applied Algebra. He is currently writing up research on the mathematics of entanglement, a resource for quantum computing. In addition to pursuing these research interests, Dr. Klucznik is developing courses at the interface of mathematics and biology. When not doing mathematics he learns Polish and enjoys swimming, cooking, and music.

Cathie Leary is an alumnus of St. Bonaventure University, graduating in 1975 with a B.S. in mathematics. She earned an M.A. in mathematics at SUNY at Albany. In 1985, Professor Leary returned to St. Bonaventure as a faculty member. Outside of the University, she enjoys music, acting, dancing, and swimming. She performs for the Olean Community Theatre and was until recently the director of the Spring String Festival at Houghton College. Her love of swimming may be traced back to her days as a student at Bonas, when she was a member of the inaugural women's swimming team. The Swedish proverb “The apple doesn't fall far from the tree” is supported by Professor Leary's family, as two of her three children are actors and the third is a computer programmer.

Chris Leary has a B.A. in mathematics from the University of Connecticut and M.A. and Ph.D. degrees in mathematics from the State University of New York at Albany. He has been at St. Bonaventure since 1985. Dr. Leary authored the instructor’s manual accompanying the third edition of “For All Practical Purposes” (COMAP), a liberal arts mathematics text used extensively across the nation. His main mathematical interests lie in algebra (modules over commutative rings) and analysis (summability in Banach spaces), and he has published in both fields. He initiated the study of Dedekind finite objects in module categories in his most recent paper. Dr. Leary has served as a referee for the Proceedings of the American Mathematical Society and for the Real Analysis Exchange. He has been an external evaluator for tenure applicants at other universities. At St. Bonaventure, Dr. Leary has supervised four honors projects for mathematics majors. He organizes (along with Dr. Hill) the SBU Student Chapter of the Mathematical Association of America and is the faculty advisor for the New York Omega Chapter of Pi Mu Epsilon (the national honorary mathematics society). Outside the classroom, he has been spotted on stage, often performing for the Olean Community Theatre and the Olean Theatre Workshop.

Harry Sedinger has a Ph.D. in mathematics from Carnegie Mellon University. Before coming to St. Bonaventure in 1981, he taught at colleges in Pennsylvania, Oregon, Wisconsin, and West Virginia. He also spent six years working in applied mathematics and computer science at the Johns Hopkins University Applied Physics Laboratory in Silver Spring, Maryland and at Floating Point Systems in Portland, Oregon.

Dr. Sedinger's primary interest in mathematics is problem solving. He has had more than 135 problem solutions published in mathematical journals and has been cited for more than 540 others. He is currently on the Advisory Panel for the American Mathematics Competition, through which he writes and edits problems for the American Mathematical Contest (AMC) 8, the AMC 10, the AMC 12, and the American Invitational Mathematical Examination (AIME). In 2004 he was the author and grader of the Michigan Autumn Take-Home Challenge, a team-oriented mathematics competition for undergraduate mathematics majors from colleges and universities in the Michigan area.

He loves teaching calculus and has been active in the Advanced Placement Calculus program for many years. His personal interests include running, canoeing, traveling, camping, and spending time with his five cats.
