Gregory is a PhD Candidate in Cyber Security for Urban Critical Infrastructure at MIT. His dissertation topic investigates technical, policy and managerial facets of securing city-sustaining critical infrastructure from cyber threats.  Modern cities rely on smart grids, connected water networks and internet-enabled transportation infrastructure. But, each step a city takes in this direction increases its reliance on the Internet of Things (IoT) and thus exposes it to even more serious cyber breaches. This threat is real and local as has been seen from the recent cyberattack on a Rye, New York dam, where Iranian hackers took control over the system controlling flow rates for the water.
