DR. DIPANKAR CHATTERJI

Dr. Dipankar Chatterji, born April 20, 1951 has skilfully combined his ability in biophysics with that in molecular biology to produce some original work relating to the transcription process of DNA. He is one of the leading experts working on an area of gene regulation, called gene transcription. Dr. Chatterji has shown that the inhibiton of transcription by antibiotic rifampicin in bacteria is dependent on the promoter sequence as well as on the initiating nucleotides. He is a life member of the Society for Cellular and Biological Chemists in India and of the Society for Cell Biology in India. He is also a Member of the Protein Society, USA. Dr. Chatterji was a Visiting Professor, National Institute of Genetics, Japan, and is currently Deputy Director of the Centre for Cellular and Molecular Biology, Hyderabad.

Dr. Dipankar Chatterji’s fellowship work was carried out at the Centre for Cellular and Molecular Biology, Hyderabad. He undertook a tour of the USA, visiting the laboratory of the National Institute of Health, Bethesda. He attended the FASEB Summer Research Conference at Vermont, Saxton River. He also spent some time working in the laboratory of the Johns Hopkins University, Baltimore as a Visiting Professor.

RESEARCH INTEREST

My area of study is theoretical biology, nonlinear dynamics and complex systems with a view to understand the logic & design of underlying biological processes. The primary interest is to study the evolution and maintenance of spatiotemporal organization in biological systems spanning multiple spatiotemporal scales – from ecological to genetic. I have studied mechanisms of self-organization in collective dynamics in spatially extended systems (e.g. metapopulation, excitable tissues, etc), and the adaptive role of biochemical nonlinearities present in biochemical pathways. The three areas of research are –

Biochemical Pathways & Gene Circuits – dynamics of genetic and metabolic regulatory circuits; artificial regulatory networks; deterministic and stochastic modelling; transient cellular processes; Comparative genomic study of biochemical pathway evolution in different organisms; modelling protein structures using network theory.

Pattern Formation & Collective behaviour: Pattern formation during development and inter-cellular communication; Role of space, interaction strength and local dynamics. Synchronization and controlling spatiotemporal dynamics; bursting dynamics of excitable tissues; and evolution of the collective.

Modelling Ecological systems – Single discrete population growth models, and metapopulation dynamics under ecological processes; Interacting species models (host-parasite, prey-predator, etc.); and spatiotemporal analysis of disease data.
