Hi, I'm Ralph.


I'm a machine learning engineer at Comcast Labs, working on speech and language technology. I publish under the guidance of Jimmy Lin at the junction of natural language processing, speech recognition, and deep learning.

I've served as a reviewer for AAAI, AACL-IJCNLP, EMNLP, NAACL, a CVPR workshop, and an ICML workshop.
