Hello! I am a fourth-year graduate student in the Computational Linguistics group at the University of Toronto. I am supervised by Gerald Penn. I completed my Master's degree, also at the University of Toronto, and before that, I received my undergraduate degree from the University of British Columbia, where I worked on opinion summarization and was supervised by Giuseppe Carenini.

Last summer, I interned in the Speech Group at Microsoft Research, where I worked with Xiao Li. I am currently interning again at MSR in the NLP group with Lucy Vanderwende and Hoifung Poon. Here is my CV [pdf].

Personal

I enjoy playing German board games. Here is my (rather small) collection:

To relax, I play piano and do Tai Chi. I know someone who is good at finding three-element subsets of Z34 that sum to 0, an activity that I also partake of.
