Hendrik J.M. Weerts was named director of the High Energy Physics Div. at the US Department of Energy's Argonne National Laboratory. Weerts, a professor in the Department of Physics and Astronomy at Michigan State University, spent last year at Fermi National Accelerator Laboratory doing research on the proposed International Linear Collider and on the DO (DZero) Experiment, a worldwide collaboration of scientists conducting research on the fundamental nature of matter. That research is focused on precise studies of interactions of protons and antiprotons at the highest available energies, searching for subatomic clues that reveal the character of the building blocks of the universe. Weerts has been a member of the High Energy Physics Advisory Panel to the Department of Energy and the National Science Foundation and is a fellow of the American Physical Society.
