Get in touch

For research questions, departmental business, or just to say hi.

Electro-mail

The best, most convenient, and most reliable way to get hold of me.

gjleusch@syr.edu

The old math.syr.edu address is retired and should not be used, thanks.

Paper-mail

It’s slower, less reliable, and infuriatingly old-fashioned, but snail mail is better for boxes of books, and you get to feel kinship with those great epistolary novels of the nineteenth century.

A few notes

Prospective graduate students: admissions are handled by the department rather than by individual faculty, so the useful first step is a formal application mentioning algebra as an interest. See Students for more.

Departmental business: my term as chair ended in June 2026, so for anything that needs the chair’s office rather than me personally, please see the department’s administrative contacts.
