I am currently the Security Analytics and Strategy Lead in the Bell Labs & CTO Security group, coordinating the development of a security analytics strategy, together with associated techniques, tools, and prototypes for real-time security analytics applied to emerging telecommunications-related technologies. Over the past years, I have held a variety of technical and managerial positions in computer science research, software, and security in Bell Labs. A theme of my research is to bridge foundations and practice.
