I was post-doctoral scholar at Portland State University in the RTG for Computation and Data Enabled Science.
Before moving to Portland, I was a postdoctoral associate at Carnegie Mellon University between Fall 2021 and Fall 2023. I graduated from the Mathematics Ph.D. program at Iowa State University in 2021.
Currently, I am keeping an eye out for industry jobs in the Portland area or remote work that would keep me in the Pacific Northwest. Please reach out to me via LinkedIn here.
I have three main research interests: extremal graph theory, anti-Ramsey theory, and zero forcing. Click here to see my publications. I am always looking for new projects and collaborators!
Some projects I am working/thinking about are:
Hypergraph clustering using information theory
Algorithms for computing leaky forcing numbers
Using strong properties to make progress for the inverse eigenvalue problem for signed graphs with multi-edges
My teaching experience includes core offerings and service classes: Calculus I-III, Business Calculus, Introduction to Proofs (for a full lists, contact me for my CV). Most recently, I taught Multivariate Analysis (21256) which covers material from linear algebra and calc 3 for social science majors. Last Fall I also taught Algebraic Structures (21373), which is an abstract algebra class for undergraduates. Most recently I taught Applied Linear Algebra (math 343) at Portland State University.
A core tenant of my teaching practice is to iterate on my teaching materials and strategies for sustained improvement throughout my teaching career. To this end, I maintain a "private" github repository for teaching materials (email me if you would like access). One improvement I am focusing on this semester is to make videos of example problems for my Multivariate Analysis class. The production quality could use some work, but you can see an example here.
