Pennsylvania and Delaware. Most members live in the Greater Pittsburgh metropolitan area, while we also have members in the Greater Philadelphia metropolitan area and in State College, PA.
The Pennsylvania Chapter of ASciNA is centered around Carnegie Mellon University, University of Pittsburgh, and UPMC, all in the urban center of Greater Pittsburgh. The membership consists of an interesting mix of longtime Austrian scientists living and working in Pittsburgh, and visitors (mostly students, post-docs, and visiting clinicians) who stay in town anywhere between 3 months and a couple of years.
As a small chapter, everybody knows everybody, and chapter meetings tend to be informal. We occasionally host visits of Austrian officials. For newcomers, we have mapped out the city and pass on the knowledge of how to do all the necessary things, and where to go for fun. Old-timers share the latest changes and the newest shortcuts they discovered.
