My thoughts after the United Nations Workshop on Responsible AI for Peace & Security
Last week, I had the privilege of attending a two-day workshop at the United Nations in New York. Co-organized by the United Nations Office for Disarmament Affairs (UNODA) and the Stockholm International Peace Research Institute (SIPRI), with support from NYU Tandon School of Engineering, we convened an international group of professors, graduate students, diplomats and UN and SIPRI policy makers to discuss how we can promote the teaching of responsible and ethical AI practices, as well as move towards safer AI in defense applications.

Congratulations to Shawn and John, 2 newly minted PhD students!
A belated congratulations to He (Shawn) Shuang and Shengjie (John) Xu for completing their doctoral dissertations! Shawn's thesis focuses on his two works: vWitness and Duumviri, which focus on new techniques for protecting the security and privacy of web users. In both works, Shawn made creative use of machine learning to detect malicious web activity John's thesis explores the techniques for co-designed processor and compilers to achieve better memory safety.
