Kathleen Biagas LLNL email GitHub
Eric Brugger LLNL email GitHub	Eric Brugger has over 25 years’ experience developing and using scientific visualization and analysis software. He is the VisIt project leader and one of the original developers of the software. He received an R&D 100 award in 2005 as part of the development team of VisIt. He has extensive experience assisting users visualize and understand their simulation data as well as providing hands on VisIt training in workshop settings.
David Camp LBNL email GitHub
Hank Childs UofO email GitHub	Hank is a full Professor in the Department of Computer and Information Science at the University of Oregon. Hank’s research focuses on scientific visualization, high performance computing, and the intersection of the two. In July of 2012, Hank received the Department of Energy’s Early Career Award to research visualization with exascale computers (i.e., computers that can do 1018 floating operations per second). Hank spent over a dozen years at Lawrence Berkeley and Lawrence Livermore National Laboratories, directing research in big data visualization. Outside of his research, Hank is best known as one of the founding architects of VisIt.
Cyrus Harrison LLNL email GitHub
Kevin Griffin LLNL email GitHub	Kevin Griffin is a Senior Developer Technology Engineer at NVIDIA where he is working on the integration of scientific visualization software with NVIDIA’s Omniverse platform and a high-level API called ANARI (Analytic Rendering Interface) that supports diverse rendering back-ends. He is also an Adjunct Associate Professor at San Joaquin Delta College where he teaches computer science courses. Kevin has previously worked at Lawrence Livermore National Laboratory where he was a Group Leader, Software Developer, and Solutions Executive for the High-Performance Computing Innovation Center.
Alister Maguire LLNL email GitHub	Alister joined the VisIt team in 2017 after receiving his B.S. in computer science from the University of Oregon. At the UO, he studied scientific visualization under Hank Childs and bioinformatics under John Conery. His primary contributions to VisIt have been in relation to supporting the engineering department at LLNL. Alister is also a primary contributor to the LAGER project at LLNL, which develops machine learning solutions for applied relaxtion in Arbitrary Lagrangian-Eulerian simulations.
Mark C. Miller LLNL email GitHub	Mark has supported VisIt and led development of Silo for scalable I/O requirements of LLNL HPC simulation codes such as ALE3D Kull, Ares, LASNEX and Overlink for 25+ years. Mark’s interests include data models and their impact on software interoperability, high performance I/O, and Software Quality Engineering (Smart Libraries) for HPC libraries.
Dave Pugmire ORNL email GitHub
Allen Sanderson University of Utah email GitHub	Allen is a Research Scientist at the Scientific Computing and Imaging Institute at the University of Utah. He has contributed to VisIt for over 10 years, most notably many of the application oriented PICS operators. He has also exploited the LibSim functionality for monitoring large scale applications.
Gunther Weber LBNL email GitHub
Brad Whitlock Intelligent Light email GitHub	Brad is the Chief Software Architect at Intelligent Light and an alumni developer of VisIt. Brad contributed to VisIt during his 15 year career at LLNL, adding too many features to name. Brad has applied his deep VisIt experience to the creation of HPC-FieldView and VisIt PRIME and has completed several VisIt projects in industry to instrument simulations, create new readers, port to new platforms, and support high order meshes. Beyond VisIt, Brad has been involved with in situ research projects such as SENSEI and he has proposed and been PI on software projects such as Scoreboard and AMT FEVER….
