Ulrich Heintz Professor of Physics

Professor Heintz carried out his undergraduate studies at the University of Tuebingen in Germany and obtained his Ph.D. from Stony Brook University in 1991. He was a postdoctoral researcher at Columbia University and a Wilson Fellow at Fermi National Lab before joining the faculty at Boston University in 1999 as an assistant professor. He moved to Brown University in 2009 as a full professor.

research overview

Heintz studies the fundamental building blocks of matter. Their interactions are described by the standard model of elementary particle physics. Heintz is interested in testing the validity of this model at very high energies. Understanding the behaviour of matter at the highest energies is important to understand how our Universe evolved from the Big Bang to its current state. Heintz carries out his research as a member of the CMS Collaboration at CERN and the D0 Collaboration at Fermilab.
