She has more than ten years of academic experience. Her research area includes multisensor systems, development of multi-functional sensors, instrumentation, and control, design of controllers for industrial solutions; IoT-based solutions. She is a member of the IEEE Instrumentation and measurement society, IET Kolkata Network, and Institution of Engineers.Prof. Joyanta Kumar Roy has been working in electronics and automation engineering since 1984 as Company Director, Consulting Engineering, Developer, Researcher, and Educationist. He graduated from the Department of Physics at the University of Calcutta, India, and received a Master of Science in Physics in 1977. He started his career as an entrepreneur in the year 1984 and founded a small manufacturing enterprise named System Advance Technologies Pvt. Ltd., dealing with turnkey execution of SCADA, automation, and industrial instrumentation system. In 2004, he obtained a Ph.D. (Technology) in Applied Physics from the University of Calcutta, India, and executed a number of projects related to control automation and instrumentation in several engineering sectors. After a long association with the industry, he started his academic career in 2005. He worked with many educational institutes as principal, dean, and professor. His research group developed low-cost non-contact liquid-level transmitters, temperature transmitters, pressure transmitters, vortex flow transmitters, mass flow meters, etc. He has contributed more than 150 scientific and technical publications in the form of books, book chapters, journal papers, conference papers, manuals, and engineering designs of industrial projects. He is a technical speaker and has given invited talks at a number of international and national-level conferences. He organized many technical events and national and international events and worked as a TPC member. He is the Founder and Chairman of the Eureka Scientech Research Foundation. He is a senior member of IEEE and Past chapter chair of IEEE Circuits & Systems, Region-10, India, Kolkata Section, Past Chairman and EC member of IET (UK) Kolkata Network, a Fellow of IWWWA, and Fellow of IETE. Presently, he is working as a Professor, Electronics and Telecommunication Engineering, at Narula Institute of Technology, Agarpara, Kolkata, WB, India, Chairman cum Managing Trustee, at Eureka Scientech Research Foundation, Kolkata and Freelance Automation Consultant Tractebel GKW Consult GmbH, India. He is serving as Editor of S2IS and a regular reviewer of research articles. His present research interest includes the development of smart measurement and control systems for water production and distribution, multifunction sensor, IoT-based m-health, valvular disease detection using heart sound, technology-assisted living, smart homes, and cities.
