DESCRIPTION:Zoom link: https://mcgill.zoom.us/j/85831178685\n\nAbstract:\n
 \nNature produces soft materials possessing exceptional mechanical propert
 ies. These properties are to a large extent related to the well-defined st
 ructures and locally varying compositions of these natural materials. Key 
 to the excellent control nature possesses over the structure and local com
 position of its materials is their fabrication: Many of these materials ar
 e formed from compartmentalized reagents that are transported to the desir
 ed locations where they are released locally. Inspired by nature\, we use 
 emulsion drops as compartments to build macroscopic granular hydrogels. In
  this talk\, I will demonstrate how we convert individually dispersed emul
 sion drops into selectively permeable viscoelastic capsules that enable co
 ntrolled localized release of reagents. These capsules are most frequently
  employed as individually dispersed delivery vehicles. In the second part 
 of this talk\, I will demonstrate how we go one step beyond the current us
 e of capsules by converting them into inks that we 3D print into strong an
 d tough double network granular hydrogels.\n\nBio:\n\nEsther Amstad studie
 d material science at ETH in Zurich where she also carried out her PhD the
 sis under the supervision of Prof. Marcus Textor (2007-2011). Her thesis w
 as devoted to the steric stabilization of iron oxide nanoparticles. As a P
 ostdoctoral fellow\, she joined the experimental soft condensed matter gro
 up of David A. Weitz at Harvard University (2011-2014). She developed new 
 microfluidic devices to study early stages of the crystallization of nanop
 articles and to produce drops of well-defined sizes at high throughputs. S
 ince 2014\, she is Tenure Track Assistant Professor at the institute of Ma
 terials at Ecole Polytechnique Fédérale de Lausanne (EPFL)\, Switzerland\,
  where she heads the Soft Materials Laboratory (SMAL). Inspired by nature\
 , her research team studies the influence of the compartmentalization of r
 eagents on the structure and properties of the materials that are formed f
 rom them. Leveraging this knowhow\, the Amstad lab develops drop-based pro
 cesses to fabricate adaptable strong and tough granular materials.\n\nThe 
 education of the next generation of scientists and engineers is important 
 to Esther Amstad. She developed a new Soft Matter course that is a compuls
 ory Master course for EPFL Material Science students where she highlights 
 the importance of biomaterials. Moreover\, she regularly organizes biomate
 rial-related conferences.\n
