Invited Speakers

Matthias Beck

San Francisco State University, USA
Matthias Beck received his Ph.D. from Temple University in 2000 and is currently a professor of mathematics at San Francisco State University. His research is in combinatorics and number theory, in particular, counting integer points in polyhedra and the application of these enumeration functions to various mathematical topics and problems.


Joanna Ellis-Monaghan

Korteweg-de Vries Instituut voor Wiskunde, Universiteit van Amsterdam, Netherlands
Jo has an undergraduate degree in Studio Art from Bennington College and PhD in Mathematics from the University of North Carolina, Chapel Hill. She is now a professor of mathematics at the Korteweg-de Vries Institute for Mathematics at the University of Amsterdam. Her theoretical research in algebraic combinatorics emphasizes graph polynomials, while her work in applied graph theory encompasses DNA self-assembly, statistical mechanics, computer chip design, and bioinformatics.


Christoph Koutschan

RICAM, Austrian Academy of Sciences, Austria
Christoph Koutschan completed his PhD in 2009 at RISC, Johannes Kepler University Linz. He is currently a senior research scientist at the Austrian Academy of Sciences. His research concerns computer algebra, symbolic summation and integration, with applications in combinatorics and physics.


Jae-Hoon Kwon

Seoul National University, South Korea
Jae-Hoon Kwon obtained his PhD in 2001 at Seoul National University, and is a professor in Seoul National University. He has been working on representation theory of quantum groups and Lie superalgebras and its interaction with algebraic combinatorics in terms of crystal bases.


Stephen Melczer

University of Waterloo, Canada
Stephen completed doctorates at the ENS Lyon and the University of Waterloo in 2017, and is now an assistant professor at the University of Waterloo. His research concerns analytic combinatorics, computer algebra, and algorithms for enumeration.


Mateusz Michałek

Universität Konstanz, Germany
Mateusz completed his PhD in 2012 at Université Joseph Fourier in Grenoble and the Polish Academy of Sciences. Currently, he is a professor at the University of Konstanz in Germany. His work involves the interactions of algebra, combinatorics, geometry, and their applications in the sciences. He is particularly interested in toric varieties and tensors.


Maki Nakasuji

Sophia University and Tohoku University, Japan
Maki completed her PhD in 2003 at Keio University and is currently a professor at Sophia University in Japan. Her research concerns analytic number theory and combinatorial representation theory.


Jessica Striker

North Dakota State University, USA
Jessica completed her PhD in 2008 at the University of Minnesota and is currently a professor at North Dakota State University. Her research interests include dynamical algebraic combinatorics, enumerative and geometric combinatorics, web bases and representation theory, and integrable models of statistical physics.


Karen Yeats

University of Waterloo, Canada
Karen Yeats works on combinatorial problems from quantum field theory and quantum gravity. They obtained a PhD in mathematics from Boston University under the supervision of Dirk Kreimer and then took a faculty position at Simon Fraser University before moving to the University of Waterloo, where they are a Canada Research Chair in the department of Combinatorics and Optimization.
