Dr. Seshan’s current research interests are in the area of methods for the analysis of high throughput data, specifically from genomic profiling such as DNA copy number and methylation arrays. He developed with Adam Olshen the CBS algorithm for the analysis of DNA copy number data and has extended the method to allele copy number estimation. He is collaborating with Drs. Begg, Olshen and Ostrovnaya on extending these methods to distinguish second cancers from metastases. He is responsible for the research computing environment for the members of the department.
