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. 

He joined the University of Melbourne, in February 2000, where he is currently a Professor in School of Computing and Information Systems. In 2008, he was a visiting professor at Department of Computer Science, University of Calgary, Canada. 

His research activity is marked by more than 150 peer-reviewed publications in major refereed conferences and journals with a strong research focus on pseudo-random sequences, network security, cryptography, and cybersecurity. He has supervised several Research Higher Degree students. He actively participates in curriculum design and has led the School through accreditation of its degrees. He has engaged at a senior level with conference activities and is a reviewer for several international journals and conferences in sequences and cryptography research.
His current research interests include Cybersecurity, coding theory, cryptography, and applications of sequences in information hiding and communications.
