J. Alexander Liddle

J. Alexander Liddle is the Group Leader of the CNST Nanofabrication Research Group. He received a B.A. and a D. Phil. in Materials Science from the University of Oxford. Alex worked for eleven years at Bell Laboratories, beginning as a postdoctoral researcher and advancing to staff scientist and technical manager. He then spent four years at Lawrence Berkeley National Laboratory in the Center for X-ray Optics, and then as Lead Scientist of the Nanofabrication Facility in the Molecular Foundry. Alex's research at NIST is focused on the physics of self-assembly, where he leads several projects on the measurement of the self-assembly of nanostructures. He holds 16 U.S. patents and has over 200 publications, including several in high profile journals such as Nature and Nano Letters. Alex has also helped organize a number of international conferences and workshops on nanofabrication and self-assembly.
