"We have to remember that what we observe is not nature itself, but nature exposed to our method of questioning." -Heisenberg

Our group studies measurement at the limits of what quantum mechanics allows. We work at all levels from theory to experiment, and collaborate broadly with groups from many areas of physics and beyond. 

Much of our research is motivated by problems in fundamental physics: searches for the most elementary constituents of nature, measurements of the basic constants of reality, and tests of the quantum nature of gravity.
