Diploma in electrical engineering, University of Karlsruhe (June 2001)
IP network and Unix systems engineer, Plus.line AG, Frankfurt (2001-2003)
Software engineer, Panasonic Europe Ltd, Langen (since 2003)

At Panasonic, I develop software for flat-panel TV sets and DVD/Bluray recorders.

I was part of the team that developed the Panasonic DMR-EX80SEGS DVD recorder.

My main topics are the DVB Common Interface (CI) and CI+.

CI+ is an enhancement of DVB-CI that improves the system's security and addresses other shortcomings that were found over the years. I was involved in writing the CI+ specification and am now working on implementing CI+ in Panasonic's products.

Iceland is one of the most interesting places I've ever been to.

Here's my favourite pictures of the 2005 trip.
