welcome to my homepage! i am working as a reasearch assistant at the database and information systems group here at fu berlin.

takustr. 9 / r165
14195 berlin

mail: khahn[at]mi.fu-berlin.de

after graduating from wilhelm-schickard-institut at university of tuebingen, i joined the working group databases and information systems in 2005. i am a member of the team of the cocoda project which deals with consistent information exchange in mobile ad hoc networks.

my reasearch interests focus on transactions in mobile environments, context-awareness, mobile web-services, especially transactional service composition and service discovery. in case you are looking for an open thesis, just feel free and drop by at my office (takustr. 9 / r165).
