Hall B Scientific Staff Bios


Veronique Ziegler


Veronique Ziegler came to Jefferson Lab in November 2011 as a Hall B staff scientist. She was a postdoctoral research associate at SLAC National Accelerator Lab from 2007 to 2011. She graduated from the Ph.D. program in experimental high energy physics at the University of Iowa in 2007. Her doctoral thesis contributed to the area of baryon spectroscopy. She received the D.C. Spriestersbach Dissertation Prize for 2008 in mathematics, physical sciences, and engineering for her work. Prior to joining the CLAS12 experiment at JLab, she worked at the BaBar experiment at SLAC. Her postdoctoral work contributed to several Dalitz plot analyses, the discovery of the ηb resonance and first evidence of the hb(1P) state of bottomonium in its rare π0 transition from Υ(3S) decay. She served as co-convener of the BaBar Quarkonium Analysis Working Group from 2009 until 2011, when she joined Hall B. She served as the CLAS12 software group leader from 2014 until 2020. She developed the CLAS12 tracking code for both the forward and the central tracking systems. She has been leading the CLAS12 track reconstruction effort since 2012, and is currently involved in an effort to develop tracking software using novel methods such as AI to allow data taking at high luminosity. As her physics interests involve hadron spectroscopy, she is a member of an analysis group dedicated to strange baryons studies.

Current Responsibilities in Hall B:

  • Lead of the CLAS12 track reconstruction software development.
  • Developer of tracking and analysis tools.
  • Developer of the Drift Chamber calibration suite.

Current Research Activities in Hall B:
