Since
November 2021, I am a full Professor
of Computer Science at
the
Ruhr-University Bochum
(RUB) - leading the Chair of Information Security. I am part of the
Cluster of Excellence CASA (Cyber
Security in the Age of Large-Scale Adversaries) and a member of the
Horst Goertz Institute for IT Security
(HGI). I am also involved as
a (part-time) Chief Scientific Advisor at NEC Laboratories Europe.
Before joining RUB, I was working as an NEC Fellow and was leading the Security research group
at
NEC
Labs in Germany. Prior to joining
NEC Labs, I was working as a
postdoctoral researcher in the Institute of Information Security of
ETH Zurich,
Switzerland. Since 2011, I hold a PhD degree in Computer
Science from ETH Zurich.
I am interested in all aspects of securityand privacy with a
focus on
Blockchain security & privacy,
ML security,and storage security.
A (rather outdated) summary of my research at NEC Labs is highlighted
in
this interview.
My full list of publications is available
here (by date) and
here (by topic).
Here, you can find my
Book on
Bitcoin and Blockchain Security published in
2016.
Selected media reports and interviews covering some of my past research can

Open Positions
TheChair of Information Security at
the
Ruhr-University Bochumhas multiple open positions for PhD students and
postdoctoral researchers in the area of system & information security,
particularly (but not limited to) those specializing in:
-
Blockchain security and privacy: we explore how to
improve the security and privacy of cryptocurrencies and modern
blockchain platforms while enhancing their performance and scalability.
- Platform/Storage security: we explore how to make use
of hardware support to improve the security and privacy of platforms.
Do
you have a solid background in blockchain technologies, or security/privacy concepts? Are you excited about building
highly performant secure systems? If so, I'd like to hear from you.
If
you are interested in applying, please send me an email with your
current CV and a description of why you think you are a good fit.
