Bill Goldman

I am a Professor in the Department of Mathematics at the University of Maryland, College Park, MD 20742. Office: 3106 Math Building, (301)-405-5124, FAX: (301)-314-0827, Email: wmg at math.umd.edu.
In Fall 2008, I am scheduled to teach Math 431, Geometry for Computer Graphics (Tuesday-Thursday 9:30am) and Math 748E, Differential Geometry (Tuesday-Thursday 11:00am).
This past semester:
- I ran a weekly seminar at Princeton University, Mapping Class Group Dynamics on Moduli spaces. An outline will be posted, summarizing the seminar, over the summer.
- During the Spring Semester of 2008, I spent my sabbatical as a Member of the Insitute for Advanced Study.
  - On March 3, I gave a short presentation on Equilateral Triangles in the After Hours Conversations, Harry's Bar, Institute for Advanced Study.
- Member, MSRI program in Teichmueller theory and Kleinian groups, November-December 2007
- Mathematics Department Colloquium, Yale University, Dynamical systems arising from deformations of geometric structures, April 9, 2008.
2007-2008 Distinguished Scholar-Teacher.
- Public lecture, October 8, 2007, "Playing pool on curved surfaces and the wrong way to add fractions," of which you may view the slides. (These slides use 4 animations, created by Ryan Hoban: a short periodic billiard trajectory on a square, a longer periodic billiard trajectory on a square, a very long billiard trajectory on a square, noneuclideant billiard trajectories converging to the golden ratio.,
Director, Experimental Geometry Lab, 3113 Math Building, which is part of my Research Interacton Team.
I recently served as Principal Investigatorr, Maryland's VIGRE project. For information contact the Department's Associate Chairs Mike Boyle (undergraduate) and Jeff Cooper (graduate).
Editor-in-Chief, Geometriae Dedicata.
- Volume 126 (April 2007) contains the Proceedings of the 2004 Banff workshop, New Techniques in Lorentz Manifolds (V. Charette, ed.) with a published and annotated version of Geoffrey Mess's influential paper, Lorentz spacetimes of constant curvature (edited by K. Scannell).
Member-At-Large, Council of the American Mathematical Society, member of the Committee on Education.
