DESCRIPTION:Prof. David Weitz\, Harvard Department of Physics\, UK\nThis t
 alk will present a new light scattering technique that can probe very smal
 l strains over large fields of view.  The strain resolution is not set by
  imaging the sample\, but instead by light interference\, providing a stra
 in resolution of less than 100 nm.  The technique will be applied to stud
 y fracture mechanics of weak gels\, and to investigate dynamics of phase-s
 eparated systems.  The talk may also describe new mechanisms for fluid dr
 iven fracture.\nReference: https://weitzlab.seas.harvard.edu/files/weitzl
 ab/files/physrevlett.127.088003.pdf\n\nBio: Weitz received his PhD in phy
 sics from Harvard University and then joined Exxon Research and Engineerin
 g Company\, where he worked for nearly 18 years. He then became a profess
 or of physics at the University of Pennsylvania and moved to Harvard at th
 e end of the last millennium as professor of physics and applied physics. 
 He leads a group studying soft matter science with a focus on materials sc
 ience\, biophysics\, microfluidics and flow in porous media. Several start
 up companies have come from his lab to commercialize research concepts.
