David Muller is a professor of Applied and Engineering Physics at Cornell University, and the acting director of the Kavli Institute at Cornell for Nanoscale Science. His current research interests include the physics of renewable energy materials, atomic resolution electron microscopy and spectroscopy and the atomic-scale control of materials to create electronic phases that cannot exist in the bulk. He is a graduate of the University of Sydney and received a PhD from Cornell University in the field of Physics. As a member of the technical staff in the physical sciences division at Bell Labs, he applied his research on imaging single atoms and atomic-scale spectroscopy to determine the physical limits on how small a transistor can be made. For this work, he was named one of the top 100 young innovators in 2003 by Tech Review Magazine, and recipient of the Burton Medal from the Microscopy Society of America in 2006. He is a fellow of the American Physical Society and the Microscopy Society of America, has received the Chau award for Excellence in Teaching in 2006 and the Provost's Award for Distinguished Scholarship in 2010 from Cornell University. He has 5 patents and has published over 150 papers, including over 35 in Nature or Science. His work has received over 10,000 citations.
