Teaching

This academic year, I'm teaching third-year undergraduate courses in the Computer Science Tripos on Cryptography and Digital Signal Processing. A variant of the latter is also offered as module L314 for Masters students. I also prepared online tutorial lectures on Unix Tools and give brief introductions to LaTeX and Julia (formerly LaTeX and MATLAB). In previous years, I also taught a second-year undergraduate course Security and for Masters students a Hardware Security Practicals module or a reading class on Forensic Signal Analysis.

Course materials pages: 2025/26, 2024/25, 2022/23, 2021/22, 2020/21, 2019/20, 2018/19, 2017/18, 2016/17, 2015/16, 2014/15, 2013/14, 2012/13, 2011/12, 2010/11, 2009/10.

PhD students: Eric Chun-Yu Peng. Former PhD students of mine that have already graduated: Piotr Zieliński, Steven Murdoch, Gerhard Hancke, Saar Drimer, Andrew Lewis, Marios Omar Choudary, Christian O'Connell, Shih-Chun You, Dimitrije Erdeljan.

We organize a Security Seminar Series, which is open to the public.
