Department of Computer Science
University of Colorado Boulder
I am a Ph.D. candidate at the University of Colorado.
Before coming here with my
advisor, Jordan Boyd-Graber,
I was a Ph.D. student at the University of Maryland, College
Prior to that, I received master's degree in computer science
from Emory University. I earned a bachelor of arts
in computer science from Hendrix College.
During Fall 2016, I am teaching undergraduate machine learning.
I do research in computational
linguistics, and I'm generally
interested in collaborating with linguists, cognitive
scientists, and of course computer scientists.
Reinforcement Learning for Simultaneous
Simultaneous interpretation is the process of translating
in real-time sentences from one language to another,
before they're finished, rather than working with
My colleagues and I are using machine learning to
teach computers to do simultaneous translation between
distant language pairs. Machine translation is hard;
simultaneous interpretation is harder. Simultaneous
between distant languages combines the most difficult parts
of both tasks. If you'd like to do simultaneous
between, say, Japanese and English, you have a problem.
In Japanese, verbs (and many other important things) come
at the end. So, you must either do some verbal gymnastics
to express your English sentences with sentence-final verbs,
or you must guess what the speaker will say before it's said.
But how do you decide when to trust these guesses? Rather
than tell the system, present the system with some things to
look for and allow it to learn from experience.

I also compose music and upload it to
SoundCloud. In high school, I wrote a novel. One
day, I'll write another.
