Dibakar Bhattacharyya, University of Kentucky Alumni Professor of
Chemical Engineering, obtained his B.S in Chemical Engineering from
Jadavpur University, M.S. from Northwestern University
and his Ph.D. from Illinois Institute of Technology. Dr.
Bhattacharyya is a Fellow of the American Institute of Chemical
Engineers. He is the Co-Founder of the Center for Membrane Sciences
at the University of Kentucky. The primary focus of Dr.
Bhattacharyya's research in the last 25 years has been in the area
of membrane separation (including biocatalytic reactions),
environmental separations/reactions with nanometals, and
functionalized materials and membranes for high capacity ion
exchange and for tunable separations. He has published over 170
technical papers and 20 book chapters, and has extensive background
in the field of pollution control and separation technologies. Dr.
Bhattacharyya has received a number of awards for his research and
educational accomplishments including the 2004 Kirwan Prize for
Outstanding Research, Larry K. Cecil AIChE
Environmental Division Award, the Kentucky Academy of Sciences
Distinguished Scientist Award and the University of Kentucky Great
Teacher Awards. He was the Director of AIChE Environmental Division
and North American Membrane Society for several years. He was the
Conference Co-Chair for the 2001 North American Membrane Society
Annual Meeting, Lexington, KY. For the 2005 AICHE Annual Meeting Dr.
Bhattacharyya was the Meeting
Program Chair (MPC). At the 2007 North American Membrane Society
Annual Meeting he was honored for his important contributions in the
His research interests include functionalized membranes (including
layer-by-layer assembly), reverse osmosis (RO)/nanofiltration
(NF)/pervaporation (PV) membrane transport, membrane-based
enzymatic catalysis; dehalogenation of hazardous
organics by nanosized metals and by Chelate modified Fenton Reactions;
RO and NF membrane work includes: organic-membrane interactions, selective
separations and protein fouling. Our recent developments include
polyfunctionalized membranes and various environmental applications
including tunable NF type separations.
There is also a critical need for new generation biofunctional membrane
materials for enzymatic bioreactors. Our joint research with the UK
Center for Membrane Sciences has demonstrated highly enhanced activities
with covalently attached site-directed enzymes in microfiltration
type membranes. Recent and current research funding include:
National Science Foundation, U.S. EPA, NSF-IGERT, DOD-WES,
Luna Innovations, Inc., SmithKline Beecham Corporation, and Daramic,
Inc, Huber Corporation, P&G.
Destruction of Hazardous Organics:
Significant advances have been made to reduce environmental
pollution problems caused by the discharge of hazardous compounds. A
variety of oxidative and reductive processes have been
developed for the destruction of hazardous organics. Our
current work includes nanosized metal based reductions, and chelated Fenton reactions
for oxidation. Current research funding include: NIEHS, U.S. EPA
STAR Nanotechnology Grant, NSF-IGERT Program, and Dow
