Short Bio

I am an Associate Professor at the COSIC research group of the Department of Electrical Engineering (ESAT) at the KU Leuven, where I lead the Privacy Technologies Team.


I hold a Master's degree in Telecommunications Engineering from the University of Vigo (2000) and a Ph.D. in Engineering from the KU Leuven (doctoral dissertation on Anonymity and Privacy in Electronic Services, 2005). I was supported by a postdoctoral fellowship from the National Fund for Scientific Research in Flanders (FWO) between 2009 and 2012. I am a faculty member since 2010. Since 2019 I am also Chief Scientist at Nym Technologies SA.


My research is focused on the design, analysis, and applications of technologies to protect online privacy, and in particular technologies that offer protection for metadata to prevent surveillance, traffic analysis, tracking, localization and profiling.


Below you can find all the details of my research, teaching, and academic service activities.


Note: I am currently only working part-time at KU Leuven, with the consequent reduction in academic activities. I am not taking any new students. If you want to apply to COSIC, please check out the group's vacancies as my colleagues may have open positions. Applications sent to me will be ignored.
