With his passion and expertise is in creating and maintaining an innovative, healthy, and excellent academic and research environment, he grew the sponsored research multi-fold.
Widely regarded as one of the nation’s leading researchers on sustainable energy, materials, and technologies, Gupta is a frequent keynote speaker and writer on the new developments and innovations. Media outlets, including Reuters, London Daily Mail, Japan News, Science Newsline, Chemistry News, and Agriculture Markets, have covered his work. His books are Nanoparticle Technology for Drug Delivery (2006, Taylor & Francis), Solubility in Supercritical Carbon Dioxide (2007, CRC Press), Hydrogen Fuel: Production, Transport, and Storage (2008, CRC Press), Gasoline, Diesel and Ethanol Biofuels from Grasses and Plants (Cambridge University Press, 2010), and Compendium of Hydrogen Energy (Elsevier, 2015), which are used worldwide.
Previously, Gupta served the U.S. National Science Foundation (NSF) as director of the Energy for Sustainability program. Currently, he provides expert help to NSF in its Engineering Research Centers program. He began his career a faculty member in engineering at Auburn University, rising through the ranks and serving as the chair of graduate program in chemical engineering. For his academic excellence, he has been given many notable awards, endowed professorships, and 54 research grants.
Gupta is a Fellow of the American Institute of Chemical Engineers and a Fellow of the Alabama Academy of Science. He received B.E. from Indian Institute of Technology, M.S. from University of Calgary, and Ph.D. from the University of Texas at Austin, all in chemical engineering. After that, he completed postdoctoral work at the University of California, Berkeley. Recently, he completed Management Development Program at Harvard University.

Method of forming nanoparticles and microparticles of controllable size using supercritical fluids with enhanced mass transfer
US 6620351 B2
2003-09-16
The current invention, Supercritical Antisolvent Precipitation with Enhanced Mass Transfer (SAS-EM) provides a significantly improved method for the production of nano and micro-particles with a narrow size distribution. The processes of the invention utilize the properties of supercritical fluids and also the principles of virbrational atomization to provide an efficient technique for the effective nanonization or micronization of particles. Like the SAS technique, SAS-EM, also uses a supercritical fluid as the antisolvent, but in the present invention the dispersion jet is deflected by a vibrating surface that atomizes the jet into fine droplets. The vibrating surface also generates a vibrational flow field within the supercritical phase that enhances mass transfer through increased mixing. Sizes of the particles obtained by this technique are easily controlled by changing the vibration intensity of the deflecting surface, which in turn is controlled by adjusting the power input to the vibration source. A major advantage of the SAS-EM technique is that it can be successfully used to obtain nanoparticles of materials that usually yield fibers or large crystals in SAS method. Microencapsulation via coprecipitation of two or more materials can also be achieved using the SAS-EM technique.
