# Dr Eckhard Pfluegel

**School/Department:** Computer Science & Mathematics

**Position:** Senior Lecturer

## Biography

Dr Pfluegel obtained a Ph.D. in Computer Science at Université Joseph Fourier, Grenoble (France) in 1999 after graduating with a First Class degree ("Diplom") in Computer Science (Equivalent of UK Honours and Master's degree) in 1999 at Universität Karlsruhe (now known as KIT), Karlsruhe (Germany). An experienced Senior Lecturer with 3 years of industrial practice in software engineering and over 13 years of research expertise, teaching responsibilities and professional practice, his current main area of specialism is network and cyber security. He has an active and continuous portfolio of over 40 peer-reviewed international journal and conference publications, serves as member of several technical programme committees and regularly reviews for international journals. Dr Pfluegel is leading an educational programme in cyber and network security at postgraduate level and frequently gives public lectures and talks on the topic of cyber and computer security awareness. He particularly enjoys research-informed teaching in order to bring in cutting-edge knowledge from his research into his lectures.
