Dr. Gajanan S. Bhat, CText FTI


Ph.D., Georgia Institute of Technology – Polymer and Fiber Science, Carbon FibersRecycled Plastics, Nonwoven Materials.

Brief Bio

Dr. Bhat received his bachelor’s degree in textiles from the Bangalore University in 1981, M. Tech in Fiber Science and Technology from IIT Delhi in 1984, and his PhD in Fiber and Polymer Science from Georgia Tech in 1990. His dissertation research was to understand the conversion of polyacrylonitrile-based precursors into carbon fibers. After that he joined Image Carpets, Rome, GA, a company producing fibers from post-consumer recycled polyester for carpets, where an analytical  laboratory was set up to characterize recycled plastics and fibers. Dr. Bhat joined UTK as a faculty member in the textile science program in August 1990. His research at UTK covers: (i) nonwovens – melt blown, spunbond, and biodegradable, (ii) plastics recycling, (iii) high performance fibers and composites, and (iv) multifunctional fibers and nonwovens, (v) nanofibers and nanocomposites.  He has published more than 150 original research papers, and has three US Patents to his credit.
