My name is Edward Karavakis and I'm a Senior Applications Engineer at Brookhaven National Laboratory (BNL) stationed at CERN, the European Organisation for Nuclear Research in Geneva, Switzerland. I am a member of the Nuclear and Particle Physics Software (NPPS) Group. The group in BNL's Physics Department participates in a wide range of experiments across BNL's nuclear and particle physics programs. NPPS provides software and expertise across many technical areas, with a particular emphasis on common software solutions. I am a member of the Production and Distributed Analysis (PanDA) workload management project's core development team and a contributor to ATLAS and Rubin PanDA development & operations. In my spare time, I am a regular guide to the over/underground installations of CERN since 2014.
