### 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)."

### Computer Science Majors and RockSat-C

**William Elliman**H'20 and

**Victoria Loshusan**WS'20, are among the four students who make up the 2019 Hobart and William Smith Colleges RockSat-C team. RockSat-C is a program sponsored by NASA and the Colorado Space Grant Consortium. The team has designed and built a system for measuring muon flux and magnetic fields that will be launched as one of the payloads on a sounding rocket. The payloads built by various teams will collect data during the rocket flight. The HWS team is one of nine teams that have been selected to contribute payloads to the project. Loshusan and Elliman will spend ten days in June at NASA's Wallops Flight Facility working on the project.

### Hamdan Ahmed '20 Named Newman Civic Fellow

**Hamdan Ahmed**(Hobart '20) was named Newman Civic Fellow in March. This fellowship honors students who have worked to solve problems facing their community. Hamdan is one of only 262 students to receive this honor for 2019–20.

According to the HWS web site: "The Newman Civic Fellowship, named for Campus Compact co-founder Frank Newman, is a one-year experience emphasizing personal, professional and civic growth for students who have demonstrated a capacity for leadership and an investment in solving public problems. Through the fellowship, Campus Compact provides a variety of learning and networking opportunities, including a national conference of Newman Civic Fellows in partnership with the Edward M. Kennedy Institute for the United States Senate. The fellowship also affords fellows with access to apply for exclusive scholarship and post-graduate opportunities."

### Zibitsker '19 Wins "The Pitch"

**Maxim Zibitsker**(Hobart '19) was the winner in the final round of the

*2019 Stu Lieblein ‘90 Pitch Contest*. The Pitch is an entrepreneurial competition in which Hobart and William Smith students compete for a $10,000 prize. In the final round, four finalists — chosen from a field of ten semi-finalists — present their ideas to a panel of judges in front of a live audience. Max's project,

*Aqua Salutem Technologies*, aims to develop a system to identify swimmers who are in distress and alert the lifeguards to the situation. This is the second time that Max has been a finalist at The Pitch. In addition to his Computer Science major, Max has a second major in Economics and a minor in Mathematics.

Another Computer Science major, **Tyler Andra** (Hobart '20)
was also one of the four finalists in this year's competition.

### Professor Vaughn Retires

Although his Ph.D. was in mathematical logic, Professor Vaughn has long been an essential contributor to the Computer Science side of the department. His hardware courses, Embedded Computing and Robotics, have been particularly popular, and his expertise in that area will be hard to replace.

Professor Vaughn will be missed by his colleagues and students, but he continues his association with the Department and with the Colleges as Professor Emeritus.
