Research Interests

Generally optimal stopping problems. Currently, I'm working on a few interesting problems in queueing theory:

• Analysis of response time in the M/G/1 under preemption overhead
• Scheduling in the M/G/1 from job size samples

I'm also interested in starting a project analyzing interconnection queues!

Selected Awards

• ACM SIGMETRICS Student Research Competition Graduate Division, 1st Place, 2024

Awarded for work on Transform Analysis of Preemption Overhead in the M/G/1. Competition included a poster session, followed by a research talk for semi-finalists, each evaluated by a panel of judges made up of experts in the field. The winning research was recognized for its significant contribution, innovative methods, and effective presentation, and this accolade qualifies the winner for participation in the ACM SRC Grand Finals against other first-place winners from other SIG conferences.

• MAA EPaDel Outstanding Student Mathematical Paper Prize, 2022

Awarded for master's thesis, Numerical methods in sustainability. The EPaDel Student Mathematical Papers Prize recognizes one outstanding paper written by an undergraduate student at an institution in the section that year.

• Anna Pell Wheeler Prize in Mathematics, 2022

Awarded annually to a single undergraduate at Bryn Mawr College on the recommendation of the Department of Mathematics, given solely on the basis of academic distinction and achievement in the field.

• Mary Louise Cookson Prize in Mathematics, 2022

Awarded annually to a single graduating mathematics major in recognition of exceptional service that has contributed to the life of the department.

• Community Building Honor Roll, 2021 & 2022

Recognizes and celebrates undergraduates, post-bacs, and graduate students who invest time and energy to create a sense of belonging, inclusiveness and community on campus.
