Sergey Bratus:
Sergey Bratus is the Dartmouth College Distinguished Professor in Cyber Security, Technology, and Society and an Associate Professor of Computer Science. In 2018--2024 He served as a Program Manager at DARPA's Information Innovation Office (I2O), where he created multiple fundamental research programs in cybersecurity, resilience, and sustainment of critical software. You can read about them here.
Sergey is interested in all aspects of cyber security, including Unix and Linux kernel security, software verification and cyber hardening, malware detection and reverse engineering (especially at the kernel and boot-stage firmware levels), wireless networking, digital radio, and visualizations of security-related information. He is interested in identifying and eliminating the root causes of software vulnerabilities, and he believes that this requires connecting state-of-the-art hacking with fundamental concepts of computer science. I believe that edge-of-the-art hacking has developed into a distinct discipline of computer science, even though not formally recognized as such, and that studying it is indispensable for building future computing systems we could finally trust.
Michael Brown:
Michael D. Brown is a principal security engineer at Trail of Bits where he leads the AI/ML security research team. He leads and works on a variety of research projects focused on applying AI/ML techniques to software security problems and assuring the security and safety of AI/ML systems. Michael was the leader of Trail of Bits' team that competed as a finalist in DARPA's AI Cyber Challenge (AIxCC).
Michael is a former Ph.D. (ABD) student at Georgia Tech where he studied security-oriented software analysis and transformation techniques. Michael earned his M.S. in Computer Science at Georgia Tech and his B.S. in Computer Science at the University of Cincinnati.
