Dr. Karabi Biswas completed her undergraduate studies in Instrumentation Engineering at the Indian Institute of Technology (IIT) in 1992. She received her M.Tech from Jadavpur University in 2000 and her PhD in Sensor Development at the IIT, where she is currently a member of the Sensors Development research group. Dr. Biswas is a member of the IEEE, USA, System Society of India and Indian Dairy Association. Her research areas include Sensor Development, Instrumentation System Design, and the Study of Fractional Order.

Gary W. Bohannan recently retired from teaching physics and astronomy at St. Cloud State University in St. Cloud, Minnesota. He completed 20 years of Naval Service, during which he obtained a Master's in Electrical Engineering. After retiring from the Navy, he went on to obtain a doctorate in Physics at Montana State University. He then worked as an electronics design engineer, during which he led a team that created one of the first single-component fractional order elements, which became known as the "fractor".

Riccardo Caponetto received the electronic engineering degree from the University of Catania in 1991 and the Ph.D. in electrical engineering in 1995. He worked, from 1994 to 2001, in STMicroelectronics as researcher. From 01/10/2001 until today, he works at University of Catania, Italy, D.I.E.E.I., as Assistant professor. His interests include modelling and control of complex systems, non integer order systems, soft computing techniques and robotics.
