Introduction to Bioinformatics (Lecture for CS397-CXZ Algorithms in Bioinformatics) Jan. 21, 2004 ChengXiang Zhai Department of Computer Science University of Illinois, Urbana-Champaign
Outline • What is bioinformatics? • Why is bioinformatics important? • Bioinformatics and other fields • Topics in bioinformatics
What is Bioinformatics • No standard definition! • Our definition: Management & Exploitation of Biological Information • Biological information (DNA, Gene expression, Proteins, Literature….) • Information management (search, organization, classification) • Information exploitation (pattern analysis, data mining) • Other definitions • (Broader) Computer Science + Biology, would cover • Computational Biology (biosimulation) • Bioimaging, etc • (Biased/Narrow) Only refers to one of the following • Information management tool development • Analysis of biology data http://www.colorbasepair.com/what_is_bioinformatics.html
Why is Bioinformatics Important? • Biology perspective • More and more biological information is available • Need for effectively accessing and using the information • Information analysis supplements (even may replace) web lab experiments • Computer science perspective • Excellent application domain • Poses special computational challenges • Brings computer science closer to scientific discovery • Currently growing …
The Growing Field of Bioinformatics • Research: Universities are expanding research programs in bioinformatics • Education: New degree programs are being launched • Industry: Pharmaceutical industry has a great interest in bioinformatics • Many job and funding opportunities Tour of the Course Resource Web Page
