Research

My research interests and expertise lie mainly in two categories namely, Experimental Condensed-Matter Materials Physics and Experimental Biophysics. 

  • Design, synthesis, and processing of a range of nanoscale materials using thermal CVD, electrodeposition, chemical and facile hydrothermal synthesis approaches, 
  • In particular, 2D and 3D graphene-family nanomaterials and related layered nanomaterials, nanodiamond, carbon nanotubes, nanocomposites, for renewable energy (electrochemical batteries and supercapacitors), water purification technologies and biosensing, 
  • Investigating electrode-electrolyte interfaces, various redox processes and bio-nano interfacial interactions (interfacial science), 
  • A wide range of routine and state-of-the-art structural and physical property measurements techniques are employed to achieve these goals. 
  • Topology and Geometry Aspects in Functional Materials (e.g.,Curved carbons, Schwarzites, Catenoids, lipids, proteins, elliptical microvessels etc.) – Also See the Book entitled “The Role of Topology in Materials” by Gupta & Saxena (Eds.) Springer Series in Solid-State Sciences, vol. 189, 2018.

Biographical Sketch

Dr. Gupta joined WKU Physics & Astronomy department as associate professor in August 2013. She received her BS (Hons.) in Physics from Delhi University (DU), New Delhi-India, MS degree with Solid-State Physics specialization from Indian Institute of Technology-Delhi (IITD), MTech in Laser Technology from Indian Institute of Technology-Kanpur (IITK). She came to University of Puerto Rico-Rio Piedras Campus and Institute of Functional Materials on NSF and DoE Graduate student Research Fellowships and received her PhD in Chemical Physics under the supervision of Profs. B. Weiner and G. Morell. After completing her PhD in 2002, she went to University of Cambridge in United Kingdom Department of Engineering and Electronic Materials and Device (EMD) group where she worked as a postdoctoral research associate with Prof. John Robertson. After Cambridge University, she accepted a research scholar position at North Carolina State University-Raleigh Physics Department to work with Prof. Robert Nemanich (now at Arizona State University). After that she worked at Missouri State University and University of Missouri-Columbia as assistant professor in the Physics, Astronomy and Materials Science and Electrical Engineering Department, respectively. Meaningfully expanding her research portfolio, she was awarded a NIH fellowship as senior researcher to perform experimental protein biophysics at the University of Pennsylvania-Philadelphia with Prof. J. K. Blasie. She was also an adjunct faculty teaching at Drexel University, Philadelphia in Physics and Astronomy Department. She has been a visiting scholar at the NIMS-Tsukuba, Japan, Politecnico di Torino, ItalyUniversity of Texas-Nano Tech Institute-Dallas and Los Alamos National Laboratory, NM. She has been awarded with NSF and DoE Graduate Fellowships and two patents for her PhD study and recipient of many others beyond PhD. 

Broadly speaking, her research interests literally ranges across STEM (Science Technology Engineering and Mathematics) disciplines. Specifically, her research background includes hot-filament and microwave chemical vapor deposition of diamond, nanodiamond and vertically-aligned carbon nanotube thin films, doping and growth kinetics of diamond and nanotubes, vacuum microelectronics, field emission (cold cathodes) and field emission microscopy, electrochemistry and electrocatalysis, advanced scanning electrochemical microscopy, surface/interfacial science, vectorially-oriented voltage-gated potassium ion channel protein’s structure and function and monitoring structural conformations induced by electrochemical potential using X-ray and neutron scattering techniques. In recent years, she has grown interest in an esoteric field of Topology and Geometry in Materials Science. She has multidisciplinary collaborators due to the nature of her research including electrical, mechanical, biomedical, and materials science engineering, chemistry and theoretical condensed-matter physics. She has taught in Physics, Materials Science and Electrical Engineering departments at various places and at both the undergraduate and graduate levels in USA since 2004.
