Guest Assistant Professor

About Me

I am currently an assistant professor at University of Twente. In the period between 2013 and 2017, I was a Ph.D. candidate at the same university. A number of solutions proposed in my Ph.D. thesis were deployed by network operators worldwide and some methodologies will be used by the Dutch High Tech Crime Unit. During my Ph.D., I also acted as technical advisor to the Dutch National Cyber Security Center and to the Japanese Ministry of Internal Affairs and Communications, both on the topic of Cyber Security and DDoS attacks. I presented my work in more than 30 countries. The most frequent words to describe my presentations/lectures by attendees are enthusiastic, entertaining and easy to understand (see more at http://jairsantanna. com/others_judgement). My professional objective is to become an internationally recognized researcher and teacher in Internet security, DDoS attack, and (big) data analysis. I aim to transfer my enthusiasm, knowledge, skills and experience into meaningful innovation to improve the security in all types of computer networks, especially the Internet.
