Bill Ashmanskas

As a Senior Lecturer, I teach and develop undergraduate physics courses here at Penn.  I also work on readout electronics, instrumentation, and data acquisition for High Energy Physics and for Positron Emission Tomography.  I work as a member of the Physics department’s HEP Instrumentation Group and of the Radiology department’s Physics and Instrumentation Group.
