I am an Associate Professor at the School of Computer Science, Carleton University, and co-director of Carleton Internet Security Lab (CISL). In 2018, I was a Senior Research Scientist in the System Security group of ETH Zürich, Switzerland. My research interests are network and Internet Security. This includes SDN security, Web security, TLS, DNSSec, authentication, and secure Internet geolocation. I generally use Internet measurements to understand and solve problems related to Internet systems' security.
