Hi! I'm Ralph.


I'm a first-year PhD at the University of Waterloo under the supervision of Jimmy Lin. I work at the junction of natural language processing, speech recognition, and deep learning.

I've designed a speech recognition system in production that answers millions of daily voice queries, I've published several papers, and I've helped a Velocity startup win $35K.
