About Me (徐浩然)

I am a Ph.D. student in Computer Science at Johns Hopkins University, affiliated with the Center for Language and Speech Processing (CLSP), co-advised by Philipp Koehn and Kenton Murray. My most recent research focuses on Machine Translation, Large Language Models, and Cross-lingual Learning.

I also had good fortune to intern at Microsoft Research, Meta (Facebook) AI Research and Amazon Alexa AI.

I will join Microsoft GenAI as a Senior Researcher starting from this Fall!
