I am a professor at the University of St. Gallen in Switzerland at the School of Computer Science, where I lead the Cybersecurity and Applied Cryptography group. I am also affiliated with Chalmers University of Technology in Sweden. Formerly, I held positions as a visiting professor at the department of Computer Science at ETHZ, a visiting associate professor at Tokyo Institute of Technology and a visiting scholar at Harvard University. After receiving my PhD (2007), I was a visiting assistant professor at Vrije Universiteit in Amsterdam and then a postdoctoral fellow at TU Delft and a Marie Curie fellow at EPFL. In 2013, I joined Chalmers University of Technology and the department of Computer Science and Engineering. I have been active both in European and National research projects, while I have been awarded the VR (Swedish Research Council) young researcher project grant, the Rubicon Research Grant by the Netherlands Organization for Scientific Research (NWO) and a Marie Curie Intra European Fellowship.

My name: Katerina is the short version of Aikaterini (official first name, used in my publications). Κατερίνα Μητροκώτσα is how my name is written in Greek.
