Summer REU Students Win Awards

For the third time, the Department hosted a Natural Science Foundation Research Experience for Undergraduates (REU) in Mathematics in the summer of 2021. Ten students came from colleges and universities around the country to live and work on our campus for nine weeks. The students experienced researching closely with a faculty member and a team of peers, practiced and honed their mathematical writing and presenting skills, participated in a colloquium series of invited speakers, and traveled to graduate schools (Cornell and the Rochester Institute of Technology) to learn about specific programs and the graduate experience in mathematics more generally. This summer the students worked with Prof. Jennifer Biermann in algebraic combinatorics, Prof. Jonathan Forde in mathematical virology, Prof. Yan Hao in neuron networks, and Prof. Erika L.C. King in graph theory.

At the end of the nine weeks, the students remained on campus to attend the Mathematical Association of America (MAA) conference MathFest, which was held virtually. Each of the four research groups gave a virtual talk. Their talks were among nearly one hundred undergraduate talks at the conference. Both Prof. Hao and Prof. Biermann’s groups won MAA Outstanding Student Paper Session Presentation Awards, and Prof. Forde’s group won The Andersen Prize, awarded in memory of Janet Andersen by the Special Interest Group of the MAA for Mathematical and Computational Biology, and recognizing an outstanding presentation and work in areas related to mathematical biology.

2020-21

It is just over a year since the pandemic forced the Colleges to switch to fully remote learning in the middle of the Spring 2020 semester. It has been a long and in many ways difficult year. A lot has happened, but no news about the 2020–21 academic year has made it onto this web site.

The Department of Mathematics and Computer Science, like the rest of the Colleges, has been offering a mix of in-person, remote, and hybrid courses this year. With no Winter Break or Spring Break, the semesters have seemed long, and many of us — students and faculty alike — are feeling at least a little burnt out. However, we are encouraged by the rollout of Covid vaccines, and we hope that things will be mostly back to normal next Fall.

The department was joined this year by a new Visiting Professor of Computer Science, Hanqing Hu. Professors Alden Gassert and William Simmons continued as visiting professors (Professor Simmons for the Fall semester only). Professors Gassert and Hu will return as visiting professors next year. The Math Intern for the year was Hadley DeBrine WS'20.

The REU that was canceled last summer will go forward this year. Unfortunately, both the Department's Fall picnic and its Spring dinner were canceled this year, but we look forward to resuming both events next year.

Math REU, Summer 2020

Update: Because of the Covid-19 pandemic, the 2020 REU has been canceled. However, an REU is planned for summer 20201.

The Department will host a Natural Science Foundation Research Experience for Undergraduates (REU) in Mathematics in Summer 2020. The National Science Foundation funds REUs at colleges and universities around the country. This will be the third year that the program has been offered at Hobart and William Smith Colleges.

Ten students will take part in the REU. Most of the students come from other colleges, but for each of the past two summers, one HWS student has participated: Nick Mckenny H'20 in Summer 2018 and Connor Parrow WS'21 in Summer 2019.

Topics this summer will include algebra with Professor Biermann, graph theory with Professor King, Neural Networks with Professor Hao, and mathematical virology with Professor Forde.

Applications are due by February 14. Visit http://math.hws.edu/REU/index.html for more information.

Professor David Eck Earns Faculty Teaching Prize

While the fact that Professor Eck is a highly skilled and beloved teacher is no news to students who have taken a class with him nor to colleagues who have worked with him, this year Professor Eck was recognized as such by the entire HWS faculty. Each year the Committee on Faculty Research and Honors chooses one faculty member from all submitted nominations to honor with the faculty prize for teaching. The winner for 2019 is Professor Eck! Read more about it on the HWS website here.

Professors Bring REU Program to HWS

In 2018, Professor Rusinko, together with Professors Forde and King, won a grant to run a Research Experience for Undergraduates (REU) in mathematics at HWS. The REU runs for nine weeks each summer with ten students, at least eight of which are from other institutions across the country. In the summer of 2018, mathematics major Nick Mckenny ’20 participated in the REU and this summer mathematics major Connor Parrow ’21 is participating. The majority of the mathematics faculty in the department will be participating as research mentors at some point over the course of the grant. During the summer of 2018, Professor Rusinko lead research in mathematical phylogenetics, Professor Biermann lead research in algebraic combinatorics, Professor Gassert lead research in number theory, and Professor King lead research in graph theory. This summer, Professor Rusinko again is leading research in mathematical phylogenetics, Professor Bell is leading research in graph theory, and Professor Forde is leading research in mathematical virology. Students experience researching closely with a faculty member and a team of peers, practice and hone their mathematical writing and presenting skills, participate in a colloquium series of invited speakers, and travel to graduate schools to learn about specific programs and the graduate experience in mathematics. Below is a picture of the Summer 2018 group at the final dinner and poster session.

Qingyi Lu Completes Honors Project

Qingyi Lu WS'19, a double major in mathematics and computer science, has completed an Honors project, "Machine Learning for Phylogenomics: Improving Statistical Binning Techniques for Species Tree Reconstruction." The project was mentored by Professor Joseph Rusinko.

An Honors project is a year-long independent project, usually undertaken in a student's senior year, culminating in substantial Honors theses and an oral examination by a panel of three examiners. Lu's project looked for ways of improving classification of organisms into phylogenetic trees. According to her abstract, "Phylogenetics studies the evolutionary history among a set of individuals, genes or species, which plays an important role in biology. Because past evolutionary events cannot be directly observed, statistical models are needed to estimate the phylogenetic trees. Consequently, accurate estimations of phylogenetic trees could provide effective evidence for studies in biology." In the project, Lu approached the problem by implementing "four machine learning techniques (K-Nearest Neighbors, Support Vector Machine, Random Forest and Neural Network)."
