Come and help defend the nation in cyberspace! In the Cyber Operations & Analysis Technology Group at MIT Lincoln Laboratory, we research challenging technical problems in cyber security, develop new technologies, and prototype first-of-a-kind systems. We have particular focus on enabling human operators and improving operational systems, orienting our work toward strong practical impact. We work across a variety of cutting-edge national-security applications: Quantifying risk posed by adversary cyber threats to key national security missions, enhancing the cyber security and resilience of critical infrastructure and other operational technology, protecting and defending U.S. weapon systems in cyber contested environments, helping the nation's cyber operators do their jobs better, faster, and at greater scale, and creating game-changing capabilities for defensive cyberspace operations. As an interdisciplinary group, we innovate by drawing insights from computer science, software engineering, data engineering, data science, artificial intelligence/machine learning, electrical engineering, mathematics, statistics, physics, and allied technical fields. We collaborate with research partners across MIT, offering frequent opportunities to team and learn in new areas.
