Peter Elmer is an experimental particle physicist whose area of expertise is developing the software and computing systems needed to operate and produce scientific results from high energy physics experiments. His current research focuses on the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN). In the past he has worked on the ALEPH experiment at CERN and the BaBar experiment at the Stanford Linear Accelerator Center (SLAC). He received a Ph.D. in Experimental High Energy Physics from the University of Wisconsin - Madison.

The LHC experiments have already produced exciting results such as the discovery of the Higgs Boson in 2012, leading to the 2013 Nobel Prize in Physics. They are now embarking on an evolving series of upgrades and data taking periods over the next 15 years to realize the full scientific potential of this machine. Elmer was a key player in developing the computing model of CMS and managed the implementation of much of the core software used today by the experiment. His current role is focused on R&D and planning for upgrades of the software and computing system required in the coming years and for the high luminosity running at the LHC in the 2020's.
 
He is a member of the US-CMS Software and Computing Project Execution Team as well as Principal Investigator for three NSF-supported collaborative research projects: "SI2-SSI: Data-Intensive Analysis for High Energy Physics (DIANA/HEP)""Particle Tracking at High Luminosity on Heterogeneous, Parallel Processor Architectures" and "Conceptualization of an S2I2 Institute for High Energy Physics". He is a member of the startup team for the HEP Software Foundation and was a founder for a series of schools sponsored by the Italian Istituto Nazionale di Fisica Nucleare (INFN) entitled "Architectures, tools and methodologies for developing large scale scientific computing applications".
