"Live 3D Modeling with Colloids"
Colloidal particles in suspension form liquid, crystalline and glassy phases similar to those formed by atoms. Since the particles are "fat" (~1μm) and "slow" (~0.1s), they can be individually tracked in space and time by confocal microscopy. Dense colloidal systems therefore serve as "analog computers" to study the dynamics of defects in crystals (vacancies, stacking faults, dislocations, grain boundaries), crystal nucleation, crystal-liquid interfaces, and the fundamental mechanisms of the deformation of glasses.
Dr. Frans Spaepen is the 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 PhD in Applied Physics from Harvard University in 1975.
He joined the faculty of the Division of Applied Sciences at Harvard in 1977 as an 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 2000-2001 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 2008-2009, he was interim dean of the School of Engineering and Applied Sciences; and in 2009-2010, he was interim director of Harvard's Center for Nanoscale Systems.
