Jeremiah completed his PhD on Usable Human Authentication at Carnegie Mellon University under the supervision of Manuel Blum and Anupam Datta. Prior to joining Purdue he also spent a time at Microsoft Research New England as a postdoc and as a research fellow at the Simon’s Institute for the Theory of Computing. Professor Blocki has made fundamental contributions to the theory of memory hard functions --- an important cryptographic primitive which can be used to protect low entropy secrets such as passwords against brute force attacks. Broadly, his research interests include cryptography, usable authentication, passwords, differential privacy, game theory and learning theory. One of his more ambitious research goals is to develop cryptographic protocols that are so simple that a human could execute them without receiving assistance from a trusted computer.
