**Editorial work**- I'm on the editorial board of these journals which are
Diamond Open Access,

that is, with no charges for authors or readers:- Algebraic Combinatorics

(see this press release, Inside Higher Ed article, Europ. Math. Soc. newsletter article, Directory of OA Journals profile) - Combinatorial Theory

(see this press release, this video interview with one of the editors, in German with subtitles) - Confluentes Mathematici

(published by Centre Mersenne in Grenoble, similar to*Algebraic Combinatorics*above)

- Algebraic Combinatorics
- I'm also an editor for

**Research software**- TUTTE-
C code written by UROP student Michael Barany,

to compute the Tutte polynomial of a matrix

over the integers or finite fields of prime order. - CHEMOGALE-
some JAVA applets related to phase diagrams

and geochemistry, produced by Sam Peterson.

- TUTTE-
C code written by UROP student Michael Barany,
**Research diagrams!**

Lucky am I to have friends who can get computers to draw ...- the Hasse diagram for the
higher Stasheff-Tamari order

on the triangulations of a cyclic 3-dimensional polytope with 7 vertices,

(produced by Jörg Rambau).

- the graph of all
**reduced words**for the longest element in the

rank 3 finite Coxeter groups, that is, the orthogonal symmetries

of these regular solids: (produced by Rob Edman).

- the Hasse diagram for the
higher Stasheff-Tamari order
- Curriculum vitae (not necessarily up-to-date)
