### Research Overview

My more recent research has been related to voting theory, gerrymandering and recreational mathematics. Specifically, I am interested in the prevalence of voting anomalies (such as instances of monotonicity or no-show paradoxes) in real-world ranked-choice voitng elections, particularly those in the Bay area in California. I am also working on a group of researchers out of Duke University who are using outlier analysis to identify gerrymandering. I also dabble in a number of recreational math topics such as the structure of the different end-behaviors found in the game Enemy Protector and strategies for winning the linear algebra game MatRixToe.

### Undergraduate Research

**2019- :**Camarie Schmidt is looking into the optimal outlier to drop in order to most improve a set of scores (for example, a set of homework assignments). While trivial if all assignments are scored equally, the question is much less obvious when assignments are weighted differently.

**2019 (Spring):**Sophie Kestner and I investigated how to apply efficiency gap calculations (used to measure gerrymandering) to situations with more than two parties. Sophie presented at High-PURCS.

**2018-2019:**Matt Knipfer and I worked on modeling ranked-choice elections and analyzing a new voting method. The big challenge of studying real-world ranked-choice elections is that there is so little data available to analyze. The way researchers get around this is to create models for the data and then analyze those models (for, say, the prevalence of monotonicity anomalies). Matt and I worked on a model to accurately match the truncated data typically produced in real-world IRV elections. We also investigated a voting method blending elements of Borda count, instant-runoff, and approval voting, to see which fairness criteria it would satisfy and fail. Matt also presented at MAA-SE.

**2017-2018:**I worked with Joanna Fass to investigate optimal strategies for different players in the game MatRixToe, over a variety of different rule structures. Joanna presented her research at MAA-SE and won a best-presentation award. Which I probably shouldn't take credit for, but I will anyway.

**2016:**I worked with Nick Zayatz and David Naylor on the prevalence of monotonicity anomalies in real-world instant-runoff elections. They created a program that looked for monotonicity anomalies in data from San Francisco and Alameda county (in California), and Burlington, Vermont. I have since built on that program to run elections using other voting methods and looked for other kinds of anomalies such as the no-show paradox. David and Nick presented on their findings at multiple conferences, and have gone on to fulfilling jobs in computer science which have nothing to do with voting theory.

### SoTL Research

I am currently involved in a SoTL project with Jenny Fuselier investigating the benefits of a metacognitive intervention on student improvement in introductory math courses. We gave a presentation about metacognitive study habits (along the lines of prior work done by Saundra MacGuire in Chemistry classes) to students who had done poorly on their first test in a math class. We then followed the students to see whether or not the presentation helped them improve their test scores over the course of the semester. The research is currently in the data analysis phase.
