Jens H. Gundlach, Ph.D., is Professor of Physics at the University of Washington in Seattle. Born in Germany he studied physics at the Johannes Gutenberg University in Mainz. Then he conducted his thesis research in nuclear physics at the University of Washington. After graduating he became interested in testing fundamental aspects of gravity, but also came up with a new method to measure Newton’s constant, G, which yielded the most precise measurement of the mass of the Earth. Dr. Gundlach then took a right turn and founded the nanopore group at the University of Washington. His group’s work provided the first functional demonstration of nanopore sequencing. Recently his lab developed a new single-molecule tool that can resolve the activity of enzymes with unprecedented spatial and temporal precision.
