Steven Ehrlich


Steven Ehrlich is the Experimental Operations Manager and User Liaison for the NSLS. He coordinates operations with internal and external research groups and facility users, troubleshoots operational problems at beamlines, runs the weekly X-ray/VUV User Meeting, and creates and distributes weekly User Meeting minutes. He also provides NSLS experimental users an interface with machine operations and NSLS and BNL staff. Steven is also the spokesperson and local contact for beamline X18A. His research interests include structural changes of noble gases in confined media and synchrotron instrumentation.
