IMA Public Lecture:
Advances in Whole Genome Sequencing
Eugene Myers

Corporate data warehouses and the worldwide web are two sources of large volumes of data from which valuable patterns can be extracted. Another is the vast amount of genomic information being collected from plants, humans and other organisms. This workshop will bring together researchers with backgrounds in web algorithms, linear algebra, databases and data mining. The intent is to focus on the use of optimization and mathematical programming technique in these domains. Participants will be drawn from a mix of academe, computer-makers, government labs and web-oriented companies.
