Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.
Keynotes Session

Session Chair:
Fan-Bill Cheung (PSU)
Dr. Robert (Bob) Salko performs research in the area of computational thermal hydraulics to support modeling and simulation of light water reactors and molten salt reactors. His primary focus has been on development of subchannel and system thermal hydraulics codes, which includes modeling of two-phase flow and heat transfer, coupling with other reactor modeling tools, deployment on high performance computing systems, and implementing quality assurance measures and releasing software for users in the nuclear community. Bob has been working at Oak Ridge National Laboratory for approximately ten years, where he has supported efforts in the US Department of Energy Consortium for Advanced Simulation of Light Water Reactor and Nuclear Energy Advanced Modeling and Simulation programs. Prior to that, Bob obtained his PhD in nuclear engineering from The Pennsylvania State University.
