I am currently Director of SummerMath and Lecturer in the Mathematics Department at Mount Holyoke College. I share the directorship position of SummerMath, a program for young women in high school, with Char Morrow.

Math 120, Explorations in Geometry was last taught in the Spring Term 2008. The web pages were intended for students in that class, but try doing the Labs. A Calculus I web site is also available. In spring 2004 I assisted with Education 204, Learning and Reflecting on Mathematics, and I taught Calculus II for several term recently . Click on Lab Course for MHC's "bridge to higher mathematics," Math 251, which I taught in Spring 2005. From I100, Quantitative Reasoning, Fall 1999, you can access the Malthus Lecture and the Mathematical Modeling Lecture.

In June of 1999 I had the honor and pleasure of participating in the First Interdisciplinary Conference of the International Society of the Arts, Mathematics and Architecture, which was held in San Sebastien (Donostia), Spain, at the University of the Basque Country. Under construction are some pages devoted to Conference presentations. Some of the things I presented there can be reached through my geometry pages. Further information can be obtained by contacting me by e-mail. This section is Under Construction!

Frank Geary's Guggenheim Museum, Bilbao.

ISAMA took a field trip to Bilbao. Taking in Geary's architectural wonder and the sculpture of Chilida were two of the incredible treats for conference participants. Click on the museum image above for more views of the museum exterior.
