About me

I am a Ph.D. candidate from the Polymer Processing Lab in the Department of Materials Engineering at the Indian Institute of Science, Bangalore. I work on understanding viscoelastic phase separation in polymer blend in the presence of carbon nanotubes, under the supervision of Dr. Suryasarathi Bose. My research interests include developing multiphase polymer microstructures by thermally induced phase separation and in understanding their structure-property correlations using various characterization techniques, such as Rheology, Differential Scanning Calorimetry, Dielectric Spectroscopy and Atomic Force Microscopy.

Here are my resume, and Google scholar citation.

Research

My research project includes

  • Viscoelastic phase separation in polymer blend in the presence of carbon nanotubes

  • Effect of shape of nanoparticles in the demixing of polymer blends

  • Synthesis of chain-end grafted nanoparticles by controlled radical polymerization techniques like ATRP and RAFT polymerization and tuning their localization in LCST polymer blend

  • Developing antibacterial porous structures by thermally induced phase separation and electrospinning method for water purification membranes

  • Using phase separation as a tool to pattern carbon nanotubes in polymer blend in developing EMI shielding materials
