Title:

Interactive Exploration of Gene Interactions from Microarray Data

Abstract:

Microarray data provides a powerful basis for analysis of gene expression. Various data mining and statistical methods have been widely applied to microarray data to unveil patterns. In this talk, I will introduce an interactive exploration system GenExplore for analyzing various gene interactions (directed vs. undirected, pairwise vs. multi-way). I will discuss the application of graphical Gaussian modeling, loglinear modeling and constraint based causal modeling to microarray data. Since the number of samples is usually much smaller than that of genes, preprocessing and graphical decomposition techniques will also be discussed.

Bio: Dr. Xintao Wu is an assistant professor in the CS department at the University of North Carolina at Charlotte. He got his Ph.D. in Information Technology from George Mason University in August 2001. He received his BS degree in Information Science from the University of Science and Technology of China in 1994, an MS degree in Computer Science from the Chinese Academy of Space Technology in 1997. His major research interest include data mining and data mining, data privacy, and bioinformatics.
