Biography

I'm a post-doctoral researcher at National Center for Toxicological Research,US FDA, Arkansas, USA. I have worked on fuel cell and supercapacitor applications of doped carbon materials, and have published 12 articles so far in peer reviewed journals including RSC Advances, Journal of Power Sources and Electrochimica Acta. Also, I'm serving as a reviewer for several journals including Carbon and Journal of Materials Chemistry A. Education  Ph.D. in Applied Chemistry (May 16, 2015) - University of Arkansas at Little Rock, Arkansas (GPA - 4.00/4.00)  Dissertation title: Microwave assisted synthesis and characterization of heteroatom-doped carbon for fuel cell and supercapacitor applications; synthesis and characterization of conducting polymer/metal-oxide composites for gas sensing applications  M.S. in Chemistry (2012) - University of Arkansas at Little Rock, Arkansas (GPA - 4.00/4.00)  Dissertation title: Renewable resource based magnetic nanocomposites for removal and recovery of phosphorous from contaminated waters  B.S. in Pharmacy (2010) - Kakatiya University, India (GPA - 4.00/4.00) Professional experience Post-doctoral fellow - National Center for Toxicological Research, U.S. Food & Drug Administration, AR (May 2015 -present)  PBPK (Physiologically-Based Pharmacokinetic) modeling of FDA regulated nanoparticulate drug products.  Characterization of graphene by different nanotechnology methods for development of standards. Research Assistant - University of Arkansas at Little Rock, AR (2010-2015)  A unique, rapid and versatile microwave synthesis method was developed which is more economical than any other synthetic methods reported so far in the literature. The other reported processes use prolonged heating times and reducing gases.  Novel high surface area doped carbon materials were developed from renewable resource materials like tannins for alkaline fuel cell, supercapacitor and photo water-splitting applications.  Iron oxide nanoparticles impregnated wood composites were developed for phosphorous remediation from waste waters.  Doped carbon nanomaterials and iron oxide impregnated wood composites were studied extensively by different nanomaterial characterization techniques.  Tanninsulfonic acid-doped polyaniline-metal oxide composites were prepared by a facile in-situ method. The developed composites were extensively characterized by different techniques.  The conducting polymer/metal oxide composites were tested for ammonia gas sensing. They were discovered to be superior to other composites reported in the literature, due to their enhanced thermal and chemical stability properties.
