Ramesh R Bhave

Senior Research Scientist and Director, Inorganic Membrane Technology Laboratory


Ramesh Bhave is a Senior Research Scientist and the Director of the Inorganic Membrane Technology Laboratory in the Materials Science and Technology Division at the Oak Ridge National Laboratory (ORNL).  Dr. Bhave is also a University of Tennessee -ORNL Joint Faculty Professor in the Department of Chemical and Biochemical Engineering. He holds a B. S. and Ph. D. in Chemical Engineering from the University of Bombay in India. He was a Post-doctoral Research Associate in the Department of Chemical Engineering at the Stevens Institute of Technology, Hoboken, NJ.

Prior to joining ORNL in April 2008, he was a Senior R & D Manager at Pall Corporation. Dr. Bhave has more than 21 years of industrial R & D experience and was responsible for the development of a number of innovative membrane-based separation processes from laboratory scale to full-scale industrial systems across diverse industries such as chemical and petrochemical, food/beverage, pharmaceutical and biotechnology. At ORNL, Dr. Bhave leads a broad research program in the area of membrane separations supported by the DOE and industry.  He is a project leader for membrane-based rare earth elements separation supported by the Critical Materials Institute (CMI), an energy innovation hub funded by the DOE.

Areas of Research: membrane science, separations science and technology, rare earth separations, molecular sieve gas separations, membrane separations for nuclear fuel cycle research and development.
