I am a Ph.D. student at Computing and Information ScienceCornell where I am working with Prof. Jeff Rzeszotarski. Before coming to Cornell, I have been affiliated to HKU (courses) and SFU.

Previously, I have the great fourtunate to work very closely with Prof. Jiannan Wang at Simon Fraser University. I am glad to have worked with Prof. Oliver Schulte and Dr. Yudian Zheng as well.

My research interests are in helping everyday people make sense of large-scale data using statistical and machine learning approaches:
(1) Debugging the data science pipeline (e.g., Data Quality and Data Visualization);
(2) Large-scale data interactive analytics (e.g., AQP).
