About me
I am a professor in the David R. Cheriton School of Computer Science at the University of Waterloo (joined in 2017), a member of the CrySP group, and NSERC/RBC chair in data security (since 2019). Before I worked as chief research expert at SAP in Karlsruhe (2005 – 2016) and as a software architect at Arxan Technologies in San Francisco (2002 – 2004). I hold a Ph.D. in computer science from the Karlsruhe Institute of Technology (2010) and a master's degree from Purdue University (2000). I served as the inaugural director of the Waterloo Cybersecurity and Privacy Institute (2018 – 2021). I am an ACM Distinguished Scientist (2019), a winner of the Outstanding Young Computer Science Researcher Award from CS-Can/Info-Can (2019) and a winner of the Faculty of Math Golden Jubilee Research Excellence Award (2022). I am interested in security and privacy in the entire data science lifecycle. I extend real-world systems with cryptographic security mechanisms to achieve (some) provable security guarantees. My work is used in several business applications.
