Research Interests


The mission of our lab is to speed up data science. We develop innovative technologies and open-source tools for data scientists such that they can turn raw data into actionable insights in a more efficient manner. Our current research topics include:
  • Data Cleaning for Machine Learning
  • Crowdsourced Data Cleaning
  • Data Enrichment with Deep Web
  • Interactive Analytics Over Big Data
Our lab's research is generously supported in part by NSERC, Simba, and Vancity.
