Curriculum Vitae

- Since Oct. 2006: Re­se­ar­cher at the Chair for Em­bed­ded Se­cu­ri­ty - 2004: Se­mes­ter ab­road at the Uni­ver­si­ty of Shef­field, UK
- 1999: Stu­dies of Elec­tri­cal En­gi­nee­ring and In­for­ma­ti­on Tech­no­lo­gy at the Ruhr-Uni­ver­si­ty in Bo­chum
Be­si­des re­gu­lar lec­tu­res at the Ruhr-Uni­ver­si­ty Bo­chum Timo has been teaching at the Hoch­schu­le Bonn-Rhein-Sieg in Sankt Au­gus­tin and at the Fa­cul­ty of In­for­ma­ti­on Tech­no­lo­gy at the Czech Tech­ni­cal Uni­ver­si­ty (CVUT) in Pra­gue.


Timo is in­te­rested in all kinds of Em­bed­ded Se­cu­ri­ty De­vices, with a focus on
- Se­cu­ri­ty of Re­al-World Em­bed­ded Sys­tems
- RFID and Wire­less Com­mu­ni­ca­ti­on
- Fault In­jec­tion and Si­de-Chan­nel Ana­ly­sis
- Micro­con­trol­lers, Smart­cards and FPGAs
Timo's Di­plo­ma The­sis Em­bed­ded Se­cu­ri­ty Ana­ly­sis of RFID De­vices was de­cora­ted with the 1st place of the Award for IT Se­cu­ri­ty 2006 (CAST, Darm­stadt). His dis­ser­ta­ti­on Se­cu­ri­ty Ana­ly­sis of Per­va­si­ve Wire­less De­vices - Phy­si­cal and Pro­to­col At­tacks in Prac­tice ob­tained the 1st place of the award for the most out­stan­ding PhD The­sis in IT Se­cu­ri­ty 2012 (CAST, Darm­stadt).
