Praveen Kolar

Associate Professor- Agricultural Waste Management

Dr. Praveen Kolar  has a bachelor’s degree in Civil Engineering (Sri Venkateswara University, India), masters’ degrees in Aquacultural Engineering and Biological and Agricultural Engineering (Indian Institute of Technology and Louisiana State University) and a Ph.D in Biological and Agricultural Engineering from the University of Georgia. He had also worked for seven years in aquaculture industry in India, during which, his responsibilities were aquaculture water quality management, processing of seafood, and feed distribution. His current research interests include conversion of agricultural wastes into energy and value added products including heterogeneous catalysts and adsorbents. Kolar teaches courses in Food Process Engineering and Heterogeneous Catalysis.

He has professional memberships in the Institute of Biological Engineering (IBE) and the American Society of Agricultural and Biological Engineers (ASABE).
