Overview
Fei Chiang is an Associate Professor in the Department of Computing and Software, and the Director of the Data Science Research Lab at McMaster University. She is an international expert in rule-based data cleaning systems, and her research interest is broadly in data management, spanning data quality, data profiling, temporal graphs, and database systems. She holds four patents for her work in self-managing database systems. She is a recipient of an Ontario Early Researcher Award (2018). She was a Faculty Fellow at the IBM Centre for Advanced Studies. Her industry experience includes positions at Microsoft Research (Redmond), IBM Global Services, and the IBM Toronto Software Lab (Markham). She served as an inaugural Associate Director of the McMaster MacData Institute, is an Associate Editor for the ACM Journal of Data and Information Quality, and was Co-Treasurer of the 2023 International Conference on Very Large Databases (VLDB). She received her M. Math from the University of Waterloo, and B.Sc and PhD degrees from the University of Toronto, all in Computer Science.
Fei Chiang is an Associate Professor in the Department of Computing and Software, where her data management experience spans academic and industry roles, including serving as an inaugural Associate Director of McMaster’s MacData Institute. She leads the Data Science Research Group, focused on developing tools to facilitate data cleaning, improved data quality and fostering knowledge discovery. Her research in discovering data quality rules, and developing data cleaning algorithms, has been published in top-tier venues. She holds 4 patents for her work in self-managing databases, and is a Faculty Fellow at the IBM Centre for Advanced Studies, where she is the PI to develop data quality metrics for IBM Watson Analytics. She has been invited as a featured speaker and panellist, and her work has been featured in McMaster Research News, and the SOSCIP 2017 Impact Report. She is the recipient of a 2018 Ontario Early Researcher Award.
