My research interests range over low-dimensional topology and knot theory. Most of my recent work has focused on 4-manifolds, using tools of gauge theory.

**Research**

Here are

- My CV.
- A complete list of publications.
- Links to recent preprints and a list of older papers.
- A brief research description.
- Slides and videos from a few talks.

**Teaching**

Most of my courses no longer have home pages; information about assignments, etc., can be found on Latte.

My Calendar Boston Topology Seminars Calendar

Rubermania! (and the other rubermania)

So you want me to write a recommendation ...

Will you accept me as your student....?

I co-organize (with Ruth Charney and Kiyoshi Igusa) the Topology Seminar, which is also listed on the Boston Topology Seminars Calendar. Along with Catherine Broderick, I am the webmaster for the Math Department web page. .

Here is my mathematical ancestry, courtesy of the Mathematics Genealogy Project, now run at North Dakota State University.
