Professor Susanta Roychoudhury is a cancer biologist. He obtained his PhD (Biochemistry) degree in 1985 from the University of Calcutta, India. From 1985 to 1990 he did postdoctoral research at University of Pennsylvania, USA. Prof. Roychoudhury was a former Scientist (1991-2015) at the CSIR-Indian Institute of Chemical Biology, Kolkata, India and currently Chief, Basic Research, Saroj Gupta Cancer Centre & Research Institute, Kolkata. Prof. Roychoudhury is among the first few who initiated genomic research in India. As a cancer biologist, he contributed significantly to the molecular understanding of the genomic instabilities, and functional consequences of gain-of function p53 mutations in human cancer. He has also contributed significantly to the area of cancer stem cells using oral cancer models. He has developed a microarray- based gene expression signature that distinguishes the aggressive subset of early-stage oral cancer from non-aggressive one.

Currently, he is developing algorithms based on molecular classifications of ovarian, endometrial and rectal cancers for prognostic and therapeutic decision. He published more than 150 research papers and other articles. Prof. Roychoudhury has seven genomic data submissions, one patent and one copyright to his credit. He supervised 24 PhD students. Prof. Roychoudhury is the Fellow of all three Science Academies of India. He was elected as President of Indian Association for Cancer Research (2016-2019). He was awarded the J C Bose National Fellowship by the Department of Science and Technology, Govt. of India in 2017.
