Xiaoxiao (Ricky) Shi is currently a Quantitative Trader and Researcher focusing on large-scale machine learning and robust prediction techniques. After obtaining his bachelor and master degree in computer science, Xiaoxiao obtained his PhD degree in the field of machine learning and data mining with big data. Concurrently, he obtains a master degree in applied math. With the objective to apply academic research to real world practice, he has worked with several research institutes and companies, including Yahoo! Labs, AT&T Labs, Eagle Seven, Morgan Stanley Equity Trading Lab (ETL) and Engineers Gate Manager LP. Supervised by Prof. Philip S. Yu, Xiaoxiao's research interest covers the following topics:

•   Correlation among heterogeneous data, such as social advertising from both users' demographic features and users' social network;
•   Correlation among evolving time-series objects, such as finding dynamic correlations, finding the most influential financial products (shaker detection, cascading graph); further use the correlation in hedging and portfolio management.
•   Correlation among learning tasks, such as transfer learning.
