Hi! I'm Ralph.


I'm a PhD student at the University of Waterloo under the supervision of Jimmy Lin. I'm also mentored by Lili, Ferhan, and Yaoliang. I work at the junction of natural language processing, speech recognition, and deep learning.

I'm officially affiliated with Comcast Labs, Vector Institute, and Global Water Futures. I've served as a reviewer for AAAI, EMNLP, IUI (demos), and an ICML workshop.
