Dr Udaya Parampalli was born in the Udupi district of Karnataka, India. He received the BEng degree from Mysore University in 1985 and the MTech and PhD degrees from Indian Institute of Technology (I.I.T), Kanpur, in 1986 and 1993, respectively, all in Electrical Engineering. He was a research scholar at I.I.T, Kanpur from 1985 to 1991. From 1992 to July 1996, he was a Member Research Staff at Central Research Laboratory, Bangalore. From 1997 to 2002, he was an ARC Research Associate at the Department of Mathematics, RMIT University, Melbourne, Australia. 

Since February 2000, he has been working in the Department of Computer Science and Software Engineering at the University of Melbourne, Australia, currently as a Senior Lecturer. In 2008, he was a visiting professor at Department of Computer Science, University of Calgary, Canada. 

His research interests are in the area of cryptography and sequences over finite fields and rings for communications and information security.
