Research and Publications
I am interested in algebra, topology, and combinatorics.
My current research is mainly on multiple zeta
values and related topics. Recent publications:
 `Harmonicnumber summation identities, symmetric functions,
and multiple zeta values,' Ramanujan J. 42 (2017), 501526;
preprint 1602.03198.
 `On multiple zeta values of even arguments,' Int. J. Number Theory
13 (2017), 705716; preprint
1205.7051.
 `Quasishuffle products revisited' (with K. Ihara), J. Algebra
481 (2017), 293326; preprint
1610.05180.
 `Zeros of the digamma function and its Barnes Gfunction
analogue,' (with István Mező), Integral Transforms
Spec. Funct. 28 (2017), 846858.
Recent presentations:
 ``Hopf Algebra Structures on Quasishuffle Algebras and their
Applications," Algebra and Number Theory Seminar, University of Rochester,
Rochester, NY, November 29, 2017
(slides available).
 ``Multiple Zeta Values and Alternating Multiple Zeta Values Arising from
a Combinatorial Problem," Workshop on Periods and Regulators, Hausdorff
Institute for Mathematics, Bonn, Germany, January 17, 2018

A list of older talks is available, as well as
a full publication list and detailed
research description. Mainly for my own
convenience I have assembled a page of professional
links.
The material above is my own research and a
disclaimer applies to it.
