Short Biography

Abhijit Das got his BE degree in Electronics and Telecommunication Engineering from Jadavpur University, Calcutta, in 1991, ME and PhD degrees from the Indian Institute of Science Bangalore in Computer Science and Engineering in 1993 and 2000, respectively. Dr. Das has spent a year in the Department of Mathematics, Ruhr-Universität Bochum, Germany as a Scientific Assistant, and a year as a Visiting Faculty member in the Department of Mathematics, Indian Institute of Technology Kanpur. Since 2002, he has been a permanent faculty member in the Department of Computer Science and Engineering, Indian Institute of Technology Kharagpur. Currently, he is a Professor (since February 2018).

During his stay in IIT Kharagpur, Dr. Das has taught several courses in undergraduate and graduate levels. His academic and teaching interests are in the areas of algorithms, discrete mathematics, computational number theory, cryptography, formal languages and automata theory, complexity theory, graph theory, and parallel algorithms.

The main research interest of Dr. Das is computational number theory with applications to public-key cryptography and public-key cryptanalysis. He is also interested in efficient and parallel implementations of algorithms of interest in computational number theory and public-key cryptology. Some specific research areas of Dr. Das are algorithms for integer factorization and the discrete logarithm problem, elliptic-curve and pairing-based cryptography, cryptographic protocols in mobile and ad hoc networks, algebraic attacks, and massively parallel implementations of cryptographic and cryptanalytic algorithms.

Dr. Das has more than 30 publications in refereed journals and conferences. He is the (co)author of two graduate-level textbooks on public-key cryptography and computational number theory.
