Harry Weerts

Associate Laboratory Director

Hendrik (Harry) Weerts is the Associate Laboratory Director for Physical Sciences and Engineering, overseeing Argonne’s world-class interdisciplinary research in physics, chemistry, materials science, and nanotechnology. The Directorate consists of programs spanning from cosmology and understanding the early universe to developing new technologies for car batteries and the electric grid.
An American Physical Society Fellow since 1997, Dr. Weerts joined Argonne in 2005, serving as Division Director of High Energy Physics until 2014. Previously, he spent two decades with the Department of Physics and Astronomy at Michigan State University and did his research at Fermi National Accelerator Laboratory. At Fermilab he played a leadership role in hadron collider physics at the Tevatron in the Dzero experiment and was part of the team that discovered the top quark. Earlier in his career Dr. Weerts worked on the Gargamelle neutrino experiment at CERN, which discovered weak neutral currents.
From 2005 to 2012, Dr. Weerts helped lead the silicon detector design study for the International Linear Collider (ILC). He currently serves as Regional Director for Americas of the Linear Collider Collaboration and Chair of the American Linear Collider Committee. He earned his PhD from Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen University in Aachen, Germany, in 1981.
