Welcome!

My name is Aleksandra (Ola) Sobieska. As of August 2024, I am an Assistant Professor of Mathematics at Marshall University. My research resides at the intersection of commutative algebra and combinatorics.

Before coming to Marshall, I was a postdoc at the University of Wisconsin-Madison working with Daniel Erman. I earned my Ph.D. at Texas A&M University in 2020 under the guidance of Laura Matusevich.

Though Aleksandra is my legal name and the name I use on printed record, I more often go by Ola.

My work is supported by the National Science Foundation under Grant No. 2532902.

Research

Interests

Recurring themes of my research include: free resolutions and syzygies, toric ideals, numerical and affine semigroups, polyhedral geometry, nonstandard and multi-gradings of the polynomial ring, Hilbert functions and Hilbert series, Poincaré series, initial ideals and Gröbner bases, and cellular resolutions.

Most, if not all, of my research uses the computer algebra software Macaulay2.

Teaching

I have taught courses in calculus, quantitative reasoning, linear algebra, differential equations, discrete math, combinatorics, and commutative algebra. I have also worked as a project leader or TA at various summer schools and REUs. It is important to me that my classes are a positive, effective learning experience for my students.

If you are my current student, our course is likely being managed in Blackboard. If you have any questions, feel free to reach out via email.
