About
I conduct research in programming languages. For the past few years, I have primarily been focused on (1) program synthesis for "low-resource" programming languages--these are languages that are not Python, Java, etc. but are widely used in specialized fields, such as scientific computing--and (2) understanding how computer science education is impacted by large language models. Here are three representative papers on this work:
- MultiPL-E: A Scalable and Extensible Approach to Benchmarking Neural Code Generation
- Knowledge Transfer from High-Resource to Low-Resource Programming Languages for Code LLMs
- How Beginning Programmers and Code LLMs (Mis)read Each Other
I teach a variety of undergraduate and graduate courses. I have been the lead instructor for Northeastern's CS1 course several times, designed several new courses, and taught graduate seminars on topics as varied as Code LLM development and program verification.
I also serve as the Area Chair for Software at Northeastern's Khoury College of Computer Sciences.

Prospective Students
- PhD: I encourage you to apply to Northeastern. Feel free to email me to determine if our interests align. You can also determine that by reading recent papers from my group.
- Undergraduates at Northeastern: see this document for more information.
- MS students at Northeastern: I am open to the Khoury Research Apprenticeship Program. Read the document above and adapt appropriately.
