Prof. Dr.-Ing. Volker Roth
About
I am a professor for computer science
at Freie Universität
Berlin where I head
the Secure Identity
Research Group since 2009.
Before, I was a senior researcher at a research lab in Palo Alto
(FXPAL, now defunct), a visiting professor at
the Peter Kiewit Institute of the
University of Nebraska at Omaha, the CTO of a tech company in Omaha (OGM
Laboratories, now defunct), a senior researcher and deputy department
head at Fraunhofer
Gesellschaft in Germany, and a postdoc
at ICSI in Berkeley. I
received my "Dr.-Ing." (approx. Ph.D.) and my "Dipl.-Inform."
(approx. M.Sc.) in computer science
from Technische Hochschule
Darmstadt.
My primary occupation is teaching
and researching
privacy and security in information systems, with a particular interest
in the psychological acceptability of security mechanisms. I am
particularly excited by security mechanism designs that are as simple as
possible (but not simpler) and work without the need for a common root
of trust.
Contact Information and Consultation Hour
Please find my contact information on a separate
page. My consultation hour is Tuesdays at 18h. Please contact my
administrative assistant to schedule a meeting.
If you are a student in the Bachelor degree program seeking approval of
your choice of “Praktikum” then please make sure that you
have read and understood
the advice on
this page prior to contacting me.
