##### Algebra & Discrete Mathematics Seminar

**Organizer:** Dr. Jessica Striker

Seminar Information

#### Jason Boynton

*Associate Professor*

Ph.D.: Florida Atlantic University, 2006

Algebra**Email:** jason.boynton@ndsu.edu**Office: **Minard 408E20

Boynton studies commutative rings that do not necessarily enjoy the Noetherian property. In particular, he investigates Prüfer and coherent-like conditions in integer-valued polynomials and more general pullback constructions. Boynton also studies various factorization properties in integral domains.

#### Cătălin Ciupercă

*Professor*

Ph.D.: University of Kansas, 2001

Commutative Algebra**Email:**catalin.ciuperca@ndsu.edu**Office: **Minard 408E26

Ciupercă's interests lie in the field of commutative algebra. The topics of his research are multiplicity theory, asymptotic properties of ideals, Rees algebras, Hilbert functions and integral closure of ideals.

#### Torin Greenwood

*Assistant Professor and Graduate Director*

Ph.D.: University of Pennsylvania, 2015

Combinatorics**Email:**torin.greenwood@ndsu.edu**Office: **Minard 406G

Greenwood’s research involves combinatorics, probability, and mathematical biology. Ongoing projects analyze RNA folding algorithms by using tools from discrete mathematics and analytic combinatorics. He is also interested in models of percolation from mathematical physics.

#### Janet Page

*Assistant Professor*

Ph.D.: University of Illinois at Chicago, 2018

Commutative Algebra and Algebraic Geometry**Email:**janet.page@ndsu.edu**Office:** Minard 408E38

Page’s research is at the intersection of commutative algebra and algebraic geometry, typically focused on singularities of algebraic varieties, especially in positive characteristic. Algebraic objects with a rich combinatorial structure provide a natural testing ground for many questions in her research, and she is also interested in the interplay between algebra and combinatorics in these cases.

#### Tim Ryan

*Assistant Professor*

Ph.D.: University of Illinois at Chicago, 2016

Algebraic Geometry**Email: **timothy.ryan.3@ndsu.edu**Office:** Minard 408E18

Ryan's research lies in the field of Algebraic Geometry. Areas of particular interest are moduli spaces, birational geometry, higher codimensional cycles, and special varieties (in characteristic p). This includes using methods from many areas including the minimal model program, representation theory, combinatorics, homological algebra, and commutative algebra.

#### Jessica Striker

*Professor*

Ph.D.: University of Minnesota, 2008

Combinatorics**Email:**jessica.striker@ndsu.edu**Office: **Minard 406H

Striker studies enumerative, geometric, and dynamical algebraic combinatorics and is especially interested in connections to statistical physics. Combinatorial objects she investigates include: plane partitions, alternating sign matrices, posets, polytopes, and tableaux.
