Prospective students

I will not be taking on any additional Ph.D. students before Fall 2027 at the earliest.

If you are a current University of Arizona undergraduate or masters student, I will be taking on one-semester directed research students in Fall 2025 to work on SemEval 2026 shared tasks. If you are interested in such a directed research, wait until the SemEval 2026 tasks are announced (probably in August 2025), then send me an email with which task you would like to participate in, and a list of your prior experience and/or coursework in natural language processing and machine learning. I will select a small number of directed research students from the best such applications.

Graduate assistants

Please do not email me asking for paid teaching assistant positions. Teaching assistant positions are assigned by the department; I have no role in that process.

Please do not email me asking for paid research assistant positions. When I have funding for student research, I allocate it to students who are already working in my lab, typically my doctoral students.
