About Me

Hi! My name is Liam Dugan. I'm a 1st year Ph.D Student at University of Pennsylvania doing NLP research in the lab of Chris Callison-Burch.

For Summer 2022, I'll be heading to Roblox to work on Speech-to-Speech translation!

My current research deals with language modeling, human detection of generated text, machine translation, question generation, and sentence-level formality estimation.

My long term goal is to understand the implications and limitations of scale in large language mdoeling.

Feel free to look me up on Google Scholar or take my CV.
