As the director of UTNRL he demonstrated successful production of nanofibers from thermoplastic polymers by meltblowing. In July 2016, he joined UGA as the Head of the Textiles and Merchandising and Interiors (TMI) department. Dr. Bhat has published more than 200 research papers, has three US Patents and has made more than 250 national or international presentations. He has served as the president of the Fiber Society and is also an active member of INDA, TAPPI and the Textile Institute. Some of the awards/recognitions he has received include:

  • Outstanding Young Engineering Alumni by Georgia Tech (1996)

  • Distinguished Achievement Award from the Fiber Society (1999)

  • Fellow of the Textile Institute (2005)

  • TechniTex India Research Achievement Award (2008)

  • TAPPI NET division Technical Achievement Award (2014).

In addition to conducting research in the area of nonwovens since 1984, Dr. Bhat has taught nonwoven courses at UTK, and was involved in developing and teaching the introductory nonwovens training course with INDA. He has also been part of the nonwovens tutorial and INTC and TAPPI NET conferences. In addition to being part of the Textile and Nonwovens Development Center (TANDEC) conference for several years, he has served as session chair and organizing committee member of  several TAPPI and INDA technical conferences.  Many of his former students are working in reputed nonwoven companies as well. He has been working with many nonwoven companies in product development and solving problems.
