Dr. Paruchuri Gangadhar Rao, (PG Rao) has taken over as the Seventh Director of CSIR-North East Institute of Science & Technology, (formerly known as Regional Research Laboratory (RRL), Jorhat) with effect from November 18, 2002. CSIR-NEIST, Jorhat is the only National Laboratory set-up in the North Eastern Region of India devoted fully for the economic development of N E Region through the application of Science & Technology based on the natural resources available in the region. It has staff strength of over 400 people with approximately 175 scientific and technical professionals. Dr P G Rao is a Chemical Engineer of great distinction. He obtained his B Tech in Chemical Engineering from REC(NIT), Warangal in 1974 with distinction and M Tech in Chemical Plant Design from IIT, Madras in 1976. Dr Rao obtained his Ph D from IIT, Madras in 1995 for his thesis in the area of Polymer Engineering.
Dr Rao joined CSIR-NEIST (RRL), Jorhat initially in 1976 as Scientific Assistant. Through focussed research and sustained hard work, he rose to the level of Scientist E-I in 1986. He was involved in the chemical process development of agrochemicals like Phosphamidon, Quinolphos and Chlorofenvinphos which have earned FICCI award to RRL in 1982. He was involved in the development of Process design and engineering group which has provided basic engineering packages to eight processes, six of which were commercialized. In addition, he has made significant contributions to the areas of flow additives, modelling and simulation of multiphase flow in crude oil pipeline network of Bombay High, Hazard and risk analysis of chemical process plants. Dr Rao is also responsible for developing computer facilities and software packages at CSIR-NEIST(RRL) Jorhat.
In 1991, Dr Rao joined at CSIR-Central Leather Research Institute, Chennai to head the Central Design Engineering cell there as Scientist EII. There he rose to Scientist G in 2002 and also became the Head of Chemical Engineering Department. He has continued his remarkable work there till November 2002 combining scientific research with technology development, industrial applications and R&D management. At CLRI, Dr Rao’s significant scientific contributions are in the area of process development for leather chemicals, design of leather chemical plants, tanneries, design and implementation of process control systems in tanneries, Modernization of tanneries, design of leather complexes, preparation of techno-economic feasibility reports, implementation of cleaner technologies in tanneries, creation of awareness for Good House Keeping(GHK) practices in tanneries, etc. Dr Rao is also involved in the implementation of several projects through Leather Technology Mission, the successful mission project of CSIR.

Dr Rao has made contributions in the basic research in the area of charge transfer polymerization and its modelling, application of power ultrasound in leather processing. Dr Rao was on deputation abroad to countries like Germany, Holland, Italy, Russia, USA, Malaysia, Srilanka, Bangladesh and Thailand in connection with advanced research training and projects implementation. He has 83 publications in peer reviewed international journals, 33 in Indian journals, 70 papers presented in national and international seminars, proceedings, 4 patents, 3 copy rights and 8 chapters in books to his credit. He has guided 7 Ph D students and presently guiding 3 Ph D students. Dr Rao is Fellow of National Academy of Science, Fellow of Indian Institute of Chemical Engineers and past President of IIChE.
