About Me
I am a PhD student in Database Research Group @ University of Michigan CSE co-advised by Prof. Mike Cafarella and Prof. H. V. Jagadish (jag). I build systems that make self-service data preparation more usable, reliable and scalable. In Summer 2017, I interned in Trifacta working on data pattern normalization mentored by Sean Kandel, Mike Minar, and Prof. Joe Hellerstein. The work was integrated into Trifacta Cloud Wrangler launched in 08/2018. I received B.S. degrees in computer science and mathematics from Purdue University. Before transfering to Purdue, I studied EE for two years in Tianjin University in China. Please check my CV for more details.
