Short Research Description: 

Data mining of large biological datasets - cancer research

Full Research Description: 

Dimitris Anastassiou is Charles Batchelor Professor of Electrical Engineering, faculty member of Columbia's Department of Systems Biologyand of the Center for the Multiscale Analysis of Genomic and Cellular Networks (MAGNet). He is doing research on computational biology with emphasis on data mining and systems-based analysis of biomolecular data sets.

Professor Anastassiou joined the E.E. faculty in 1983. From 1979 until 1983 he was a Research Staff member at the IBM Thomas J. Watson Research Center, Yorktown Heights, NY. He is an IEEE Fellow, a Fellow of the National Academy of Inventors, the recipient of an IBM Outstanding Innovation Award, a National Science Foundation Presidential Young Investigator Award, and a Great Teacher Award from the Society of Columbia Graduates. His previous research was in the area of video technology. He is author of patents accepted as essential for the implementation of the international standards MPEG-2, AVC/H.264 and MVC used in digital television transmission and broadcasting as well as DVDs and Blue-ray discs.

His research in systems biology is directed at the discovery and elucidation of biomolecular mechanisms in cancer and the associated diagnostic, prognostic and therapeutic applications. The current focus of this research is on the development of an improved molecular biomarker for breast cancer.
