Lei Li   I am a 4th year Ph.D. student in the Computer Science Department at School of Computer Science. My advisor is Professor Christos Faloutsos. My research interest includes machine learning, and data mining. I am mainly working on time series learning, and apply it to motion capture modeling, anormaly detection, bio-image pattern mining and social network analysis. I also work with Professor Nancy Pollard and Professor Eric Xing. I got my Bachelor of Engineering degree in Computer Science from Shanghai Jiao Tong Unversity. I worked on semantic search in APEX lab with my advisor Professor Yong Yu.
