My Ph.D. advisor is Raghu Ramakrishnan.
My Master advisor is Jieh Hsiang.
I also work with Jude Shavlik, Venky Ganti, Paul Barford, Dave Musicant, Kristen LeFevre, Lei Chen on various topics.
My research interests include: Data Mining and Analysis, Data Privacy, Database, Knowledge Representation and Reasoning, and Content-Based Information Retrieval. In the following are some of the research projects that I am/was involved in.Goal-Oriented Privacy Preservation
Project webpage: http://www.cs.wisc.edu/EDAM/cybertrust
Working with Professor Raghu Ramakrishnan, I investigated the tradeoff between data utility and privacy preservation in data publishing. Specifically, I defined and studied the problem of learning classification models from (privacy-preserved) SQL aggregate views , and proposed a novel framework that allows publishing organizations to investigate privacy threats and enforce privacy requirements in the presence of various types and amounts of adversaries' external knowledge .
EDAM: Exploratory Data Analysis and Monitoring
Project webpage: http://www.cs.wisc.edu/EDAM
Working with Professor Raghu Ramakrishnan, I defined and investigated several novel data mining problems [6, 10] that combine predictive modeling and OLAP multidimensional exploration, which result in a promising research direction, cube-space data mining . I was also involved in the design of an aggregation workflow framework , research on network coordinated attack data analysis  and research on atmospheric aerosol monitoring.
Data Cleaning @ Microsoft Research
Project webpage: http://research.microsoft.com/dmx/DataCleaning
I worked with Dr. Surajit Chaudhuri, Dr. Venkatesh Ganti and Dr. Raghav Kaushik on example-driven design of record matching queries for data cleaning .
Fuzzy-Logic-Based Knowledge Retrieval
Working with Professor Jieh Hsiang, I developed a novel knowledge retrieval framework and its fuzzy logic inference theory .
Butterfly Visual Query System (English version)
Working with Professor Jieh Hsiang, I built a content-based image retrieval (CBIR) system for butterflies. Because of the success of my methodology, in the following years, there were five M.S. and one Ph.D. studies based on my CBIR architecture in Professor Hsiang's research group.
Butterfly Digital Museum (in Chinese)
During 1998 and 1999, I was involved in the design of this Digital Museum on Taiwanese Butterflies. It was a project supported by National Science Council, Taiwan.
