Georgios Portokalidis

I am an assistant professor at Stevens Institute of Technology. I obtained my doctorate degree from the Vrije Universiteit in Amsterdam. My research interests are mainly around the area of systems and network security. Currently my interests revolve around software hardening, faster and more usable security, improving software reliability and data privacy. You can find a complete CV here.

I am looking for Ph.D. Students and a postdoc interested in systems and security to join my research group. We have many exciting projects, and I am looking for people with strong programming skills, motivated, hard-working, and primarily enjoying building systems. Email me with your CV and apply for a PhD position. Stevens accepts PhD students all year long. Details...

If you are an undergraduate student interested in doing some research, email me.
