Dr. Prasanta Kumar Guha has been working as an Assistant Professor in the Department of Electronics and Electrical Communication Engineering (E & ECE) at the Indian Institute of Technology, Kharagpur since October 2010. Before that, Dr. Guha worked as a Research Associate at the Sensor Research Laboratory ((SRL), now known as Microsensors and Bioelectronics Laboratory) of the University of Warwick with Professor Julian Gardner for more than two years (2008-2010). Dr. Guha obtained his Ph.D. from the Electrical Engineering Department of the University of Cambridge in the year 2008. He has done his Masters (MPhil) from Microelectronics Research Centre (MRC, Cavendish), Cambridge University in the year 2003. Dr. Guha is presently in-charge of the VLSI Engineering Lab in the ECE Department of IIT Kharagpur. Dr. Guha has published several papers in International Journals and Conferences. His area of interest is nano-material synthesis and applications, 2D layered materials, integration of sensors, MEMS, nano-materials with CMOS platform, chemical sensors and their interface electronics.
Our group involves in the research activities of chemical sensors employing nano-materials as a sensing layer. The group mainly focuses on (i) Nano-material synthesis (particularly metal oxides) and their functionalization (ii) 2D layered material synthesis (GO, MoS2, WS2, etc.) (iii) using these materials to develop highly sensitive and selective gas sensors. Efforts are being made to develop sensors that can work near room temperature so that low power sensors can be developed. We develop sensors on the CMOS platform so, the sensors and their interface electronics will be on the same silicon die. Also, we are interested to develop sensor on a flexible low-cost substrate. Apart from the chemical sensor, the group is interested in a highly sensitive resistive humidity sensor. The group is also working on CMOS-MEMS based sensors (e.g. thermal accelerometer).
