About Me

I am a fifth-year PhD student in University of Washington NLP Research Group, supervised by Mari Ostendorf and Hannaneh Hajishirzi. My current research focuses on information-seeking conversational systems and general interactive systems. I was an intern and a student researcher at Google Research, working with Gaurav Tomar, Yi Luan and Hannah Rashkin. In the past, I spent two summers interning at MSR NLP reseach group with Michel Galley and Bill Dolan, and many other great researchers. In the past year, I also had the great pleasure to mentor Ryu Parish, a brilliant and passionate undergrad researcher at UW.

I did my master in UIUC Data Mining Research Group. During that two years, I was mainly supervised by Jiawei Han and closely worked with Xiang Ren - both of them sparked my great interest in doing research. I did my undergraduate studies in Department of Electrical and Computer Engineering also at UIUC, with minors in Computer Science, Math and Business. I was very fortunate to have J. Gary Eden as my academic (and life) mentor throughout the four years. I have also been working on various undergraduate research projects with Zhi-Pei Liang and Liming Feng.

Here is my updated CV. Feel free to email me at zeqiuwu1 [at] uw [dot] edu if you have any questions!
