I’ve worked on research projects with a number of students over the years. **If you’re interested in doing the same**, this page will give you an idea of the kind of work we do.

- In 2017, I worked with W&L students Prakriti Panthi (rising sophomore), Anukriti Shrestha (rising junior), and Eric Zhang (rising sophomore) on a number of different topics. We submittedÂ this problem (on decimal roots) and this article (on Ramanujan cubics) to M
*athematics Magazine*, and I’m still working on our third article (hopefully to be submitted soon). UPDATE: the problem on decimal roots has now been accepted for publication! - Oh, and Anukriti was featured in this article on the W&L home page!
- In 2016, I worked with W&L students Saimon Islam (rising sophomore), Aaron Schmitt (rising junior), and Pan Yue (rising sophomore) on a nice little problem concerning the sum of two squares. We collaborated with another professor/undergraduate team from Wake Forest and ended up with this 22-page article which is currently under review.
- Back in 2015, exchange student Gabriella Iwasaki, rising senior Luke Quigley, and I worked on a lovely project involving graphs associated with rings modulo 16. This picture here shows one of the problems we worked on, demonstrating that the digraph associated with multiplication by 6 modulo 16 will be of genus 2.

- In the summer of 2013, I worked with W&L student Wenda Tu (rising senior) on a nifty problem involving digraphs. This work continued with Wenda’s honor thesis in the academic year 2013-14, and that led to a joint paper which, after a few revisions, has finally been accepted and will now appear in the undergraduate math journal
*Involve*(2018, volume 2, pages 181-194) . I also worked with Ginger (Qiuchi) Sun that same summer on her interesting ideas involving the Goldbach Conjecture with polynomials.

- Back in 2012, students Ginny Huang (rising sophomore) and Cathy Wang (rising junior) worked with me on a very nice problem involving Fibonacci numbers.
- Kuan Si and I did a year-long independent study course on Fibonacci identities, during the academic year 2011-12.
- Elizabeth Twentyman wrote her honors thesis “Finding Factors of Factor Rings” with me over 2005-06; she graduated with honors in 2006.
- My colleague Wayne Dymacek and I worked with Elizabeth Townsend on her honors thesis on the inverse Galois problem; Liz graduated with honors in 2003.
- My first research student was Adam Henry; back in the summer of 1999, we did a nice project on Gaussian integers.

**Where are they now?** My research and honors students have gone on to do lots of different things after graduating W&L! But for those who went on a bit further in academia, here’s what they did.

- Gabriela Iwasaki (transfer student 2014-15) returned to Brazil and changed her major to mathematics!
- Wenda Tu (W&L ’14) is now in graduate school in statistics at the University of Iowa.
- I think that Qiuchi Sun (W&L ’13) went to grad school in economics.
- Kuan Si (W&L ’12) went to graduate school in math at Georgia Tech.
- Elizabeth Twentyman (W&L ’06) went on to math graduate school at the University of Michgan.
- Elizabeth Townsend (W&L ’03) went on to graduate school in math at the University of Chicago; after a post-doc at Michigan and some time at Williams, she is now a math professor at Haverford.
- Adam Henry (W&L ’00) got his PhD in Transportation Technology and Policy at UC Davis, and went on to posts at Harvard, Boston University, and the University of West Virginia. Adam is now a professor of government and public policy at Arizona State University.
