Alok Barua received his bachelor of technology in instrumentation and electronics engineering, master of electronics and telecommunication engineering, and PhD in electrical engineering from Jadavpur University and Indian Institute of Technology (IIT) Kharagpur in 1977, 1980, and 1992, respectively. He is a full professor in the Department of Electrical Engineering, IIT Kharagpur. With more than 30 years of teaching experience at IIT, he has published many papers in his teaching and research areas, including instrumentation, bioreactor design and control, testing and fault diagnosis of analog and mixed-signal circuits, and image processing. He has supervised several MS theses and two PhD theses on bioreactor control and instrumentation. He also holds a patent for the design of the see-saw bioreactor and is a senior member of IEEE.Goutam Saha earned his BE in electrical engineering, his ME in electronics and telecommunication engineering, and his PhD in electrical engineering from Bengal Engineering and Science University (formerly known as B.E. College) and IIT Kharagpur in 1984, 1989, and 1999, respectively. He worked as a postdoctoral research fellow at Ben Gurion University, Israel, from January to August 2002. He is currently a full professor in the Department of Information Technology, North-Eastern Hill University, Shillong, India. He has more than 25 years of teaching experience in various engineering colleges including the National Institute of Technology (Durgapur), the National Institute of Technical Teachers Training and Research (Kolkata), and other government engineering colleges of West Bengal.Satyabroto Sinha (deceased) earned a PhD in electrical engineering from the Indian Institute of Technology (IIT) Kharagpur. He taught electrical engineering at IIT Kharagpur from December 1963 to May 2005 (professor, 1982–2002; professor emeritus, 2002–2005). He advised 13 doctoral students, coauthored several books, and published approximately 60 conference and journal papers, nationally and internationally. His area of specialization was instrumentation and control. He was a national coordinator for the Technology Development Mission on Communication, Networking and Intelligent Automation for the Government of India from 1995 to 2000 and was a senior member of the Institute of Electrical and Electronics Engineers and a chartered engineer and fellow of the Institution of Engineers (India).
