Much of computational biology and bioinformatics involves transforming various types of raw data into useful information. At a May 18, 2006, symposium of the Computational Biology & Bioinformatics Discussion Group, three speakers addressed various techniques for achieving this goal. The thread going through the three talks was that they involved diverse ways of looking at genetics.
Topics discussed include the conceptual basis and practical improvement of an algorithm for partitioning genomic DNA segment copy-number data into contiguous sets with the same copy number, the use of genome-wide association data to identify a specific genetic variant connected with age-related macular degeneration, and an algorithm that successfully classifies genes into functional groups solely on the basis of their interactions.

Adam Olshen, PhD
Adam Olshen is an assistant attending biostatistician at Memorial Sloan-Kettering Cancer Center. His research focuses on the intersection of statistical genomics and bioinformatics, particularly on how copy number data can be derived from microarrays. He is also working to understand differences in gene expression data among institutions over time and to use tree-structured vector quantization to cluster protein data, and is collaborating with other researchers at MSKCC to bring computational methods to cancer research. Olshen received his PhD from the University of Washington.
Robert Klein, PhD
Robert Klein recently joined the staff of Memorial Sloan-Kettering Cancer Center as an assistant member of the Research Program in Cancer Biology and Genetics. He joined MSKCC in 2006 following completion of a postdoctoral fellowship in the Laboratory of Statistical Genetics at the Rockefeller University. He is now building a laboratory that will use an integrated combination of experimental and computational approaches to identify the genetic variants that influence the onset, progression, and treatment of cancer. His goals for the lab are to improve the power of association testing, conducting genetic studies of specific cancer phenotypes, and predicting the functionality of specific SNPs.
Roy Kishony, PhD
Roy Kishony is an assistant professor in the Department of Systems Biology at Harvard Medical School. His lab combines theoretical and experimental approaches to study epistasis networks, to understand how combinations of individual perturbations can aggravate or alleviate the effects of each other.
