After a brief overview of research in the speaker's group over the last few years, this talk will delve into his group's recent investigations of biomimetic electronic nose sensors. This will begin with a high-level summary of what is known about the mechanism underlying olfaction - laying out the conflict between the Shape and Vibration theories thereof. Thereafter, efforts to design biomimetic sensors based on the Vibration Theory will be described; covering both phenomenological quantum transport and ab initio modeling approaches. This will be followed by exposition of recent work on unifying the Shape and Vibration pictures, using graph theoretic and ab initio modeling.
Prof. Swaroop Ganguly received a BTech in Electronics Engineering from IIT Kharagpur in 1999 where he was a Jagadis Bose National Science Talent Search Scholar. He got his MS and PhD from the University of Texas at Austin in 2001 and 2005. Thereafter, he was an R&D Engineer at Freescale Semiconductor in the USA, and then a Research Scientist with Tokyo Electron Limited - seconded to IMEC, Belgium. Since 2009, he has been IIT Bombay where he is now Associate Professor of Electrical Engineering; PI of the Nanoelectronics Center; and Co-PI of the Research Park. He was a visiting scientist at IBM Research in 2010 as the recipient of the IBM-IUSSTF Fellowship in Nanotechnology. He shared an IRCC Research Paper Award in 2015, and the Patwardhan Award for Technology Development in 2018. He has co-authored the Solid-State Devices section of the TIFAC ICT Vision 2035 document. His research interests span the design and modeling of novel semiconductor devices. He has published over 100 papers in peer-reviewed journals and international conferences. He enjoys teaching Physics to Electrical Engineering students.
