Abstract:
We present a novel computational approach, Sample Progression Discovery (SPD), to discover patterns of biological progression underlying a microarray dataset. In contrast to the majority of microarray data analysis methods which focus on identifying differences between sample groups (i.e. normal vs. cancer, treated vs. control), SPD aims to identify an underlying progression among individual samples, both within and across sample groups. This is essentially a new way of asking questions. The traditional way is to ask: what is the different between A and B. In this talk, I am going to ask another question: how did A become B. In the cancer biology setting, this is to ask: how did normal samples go through progressive changes and eventually become cancerous.
Bio:
Peng Qiu received the B.S. degree from the University of Science and Technology of China, Hefei, China, in 2003, and the Ph.D. degree from the University of Maryland, College Park, in 2007, both in electrical engineering. After three years postdoctoral training at Stanford University, he is currently an assistant professor in the Department of Bioinformatics and Computational Biology, University of Texas M.D. Anderson Cancer Center. His current research interests are in bioinformatics and computational biology, focusing on signal processing and machine learning.
