Hi! I am Khodakhast Bibak,
an Assistant Professor at the Department of Computer Science and Software
Engineering at Miami University.
Previously, I was a Postdoctoral Research Associate (September 2017  August
2018) in the Coordinated Science Laboratory at the University of Illinois at UrbanaChampaign. Before this, I was
a Postdoctoral Research Fellow (MayAugust 2017) at the Department of Computer Science, University of Victoria,
from where I also received my PhD (April 2017) under the supervision of
Professor Bruce Kapron and
Professor Venkatesh Srinivasan. Prior to that, I
obtained a Master of Mathematics degree (April 2013) at the Department of Combinatorics
& Optimization, University of Waterloo,
where I was also a member of the Centre for Applied
Cryptographic Research (CACR).
Research Interests
Cybersecurity,
Applied Cryptography, Quantum Information Science (QIS), Artificial
Intelligence, and the related areas.
