Profile
Dr. Niranjan Chakraborty received his master’s degree from the University of Dhaka, Bangladesh and Ph.D. degree from the Jawaharlal Nehru University, New Delhi, India. He did post-doctoral research at the University of California, Riverside, USA. In 1998, he joined the Center for Plant Molecular Biology (CPMB) at the Jawaharlal Nehru University, New Delhi to continue his proteomics research and related studies, and oversaw the proteomics facility of the center. His group pioneered the plant proteomics research in India in the mid-nineties that continues to the current day. India’s first mass-spectrometry-based plant proteomics paper came from his laboratory. The major focus of his laboratory is to discover the regulatory proteins that influence stress tolerance in crop plants. Dr. Chakraborty’s research has led to the discovery of key metabolic pathways, impinging on the molecular circuitry used by plants in response to environmental stress. This enables the identification of key components which would help in their targeted manipulation in transgenic plants. In 2005, he moved to the National Institute of Plant Genome Research (NIPGR), New Delhi, India
Current Focus Areas
Dr. Chakraborty’s group has been exploring the stress-responsive organelle proteomes of economically important crop species for greater understanding of the molecular mechanisms of stress tolerance. The knowledge of the stress-responsive protein repertoire would contribute in understanding the role of differentially regulated proteins and/or their posttranslational modifications.
