Robert Krahn

Robert joined the Systems Engineering Group in 2015 to work as a research assistant and pursue his PhD.
The underlying topic for his research are security mechanisms in cloud computing, particularly with regard to the secure execution of applications.
The focus is on the Intel-SGX technology and the SCONE framework. In this area Robert investigates performance issues and mitigations.

Picking the right colors

We're often confronted with picking 'good' colors for papers and presentations. Some nice examples and pages that I find helpful:
The economist - 2019 in graphic detail
Nytimes - Ads on FB
