Dhruba K. Chattoraj

Senior Investigator
Laboratory of Biochemistry and Molecular Biology, CCR
National Cancer Institute
United States of America


Dr. Chattoraj received his Ph.D. in Biophysics in 1970 from the University of Calcutta, India, where he studied chromatin structure. As a postdoctoral associate, he studied nucleic acid-protein interactions involved in phage DNA replication and recombination at the University of Wisconsin with Dr. Ross Inman and at the University of Oregon with Dr. Frank Stahl. His current research interest is on replication and segregation of chromosomes in the bacterial cell cycle. He is a fellow of the American Academy of Microbiology and the President of the International Society of Plasmid Biology.
