Observing dislocations during epitaxial growth of colloidal crystals 


Prof. Frans Spaepen is John C. and Helen F. Franklin Professor of Applied Physics at Harvard University. He got his undergraduate degree, in Metallurgical Engineering, at the K.U. Leuven in 1971, and a Ph.D. in Applied Physics from Harvard University in 1975. He joined the faculty of the Division of Applied Sciences at Harvard in 1977 as Assistant Professor, was appointed Associate Professor in 1981, and Full Professor in 1983. In 1984 and 2007 he was a Visiting Professor at the University of Leuven, and in 2000-01 a Humboldt visitor in Köln and Jülich. From 1990 till 1998 he was Director of the Harvard Materials Research Laboratory/Materials Research Science and Engineering Center. From 2002 to 2013 he was the Director of the Rowland Institute at Harvard. In 2008-09 he was Interim Dean of the School of Engineering and Applied Sciences and in 2009-10, he was Interim Director of Harvard's Center for Nanoscale Systems.
His research interests span a wide range of experimental and theoretical topics in materials science, such as amorphous metals and semiconductors (viscosity, diffusion, mechanical properties), the structure and thermodynamics of interfaces (crystal/melt, amorphous/crystalline semiconductors, grain boundaries), mechanical properties of thin films, and colloidal systems as models for the study of dynamics and defects in crystals and glasses.
He is a Fellow of the American Physical Society, the Materials Research Society, and the TMS. He is a member of the National Academy of Engineering and holds an honorary doctorate from the ETH-Zürich.
