DESCRIPTION:Prof. Damien Baigl\, Ecole Normale Supérieure France\nWe act
 uate various biological and synthetic systems (DNA\, proteins\, colloids\,
  fluids\, drops) by exploiting their intrinsic soft matter properties\, ei
 ther to perform useful processes in a novel and simpler way or to study cu
 rious/unexpected phenomena. In this talk\, I will show that this approach 
 allows us to provide materials with unique properties\, such as reconfigur
 ability and stimulus-responsivity\, or to achieve useful operations like a
 utonomous microfluidics and low-cost diagnostics. I will first show that u
 sing DNA as a soft material allows us to build functional artificial cell 
 systems\, optically control gene expression or create soft reconfigurable 
 DNA nanomachines (soft DNA nanotechnology) [1]. I will then describe our e
 fforts to identify new actuation principles to make microfluidics better\,
  easier and cheaper (metafluidics)\, showing how simple LEDs or cost-effec
 tive magnets can be used to control a broad variety of fluidic operations\
 , ranging from drop and liquid marble transport to flow control and dynami
 c mixing [2\,3]. I will finally describe how new ways to harness the so-ca
 lled “coffee-ring effect” allow us to convert it into a powerful tool\
 , with applications ranging from ubiquitous particle patterning to low-cos
 t medical diagnostics [4].\n \nReferences \n[1] A. Estévez-Torres\, C. C

 ently exceptional class professor of chemistry at Ecole Normale Supérieur
 e (ENS) in Paris (France). Damien did a PhD on soft matter physics with Cl
 audine Williams in the laboratory of Pierre-Gilles de Gennes at College de
  France in Paris before a post-doc in biophysics at Kyoto University with 
 Kenichi Yoshikawa. Since 2005\, he has been working at the UMR PASTEUR (EN
 S/CNRS/UPMC) laboratory located at the Department of Chemistry of Ecole No
 rmale Supérieure (ENS\, PSL University). He was appointed ENS assistant p
 rofessor in 2005 before becoming full professor (2nd class) at University 
 Pierre and Marie Curie (UPMC\, Sorbonne Universités) in 2010\, 1st class 
 professor at UPMC in 2013. He became 1st class professor of chemistry at E
 NS in 2016\, before being promoted to exceptional class in 2018. Former me
 mber of the Institut Universitaire de France (IUF\, 2009-2014)\, he got an
  ERC starting grant in 2010 (project conducted in 2011-2015). In 2016\, he
  was awarded the Soft Matter Lectureship from the Royal Society of Chemist
 ry (RSC) for “numerous\, interdisciplinary and highly original contribut
 ions to the soft matter field in topics ranging from DNA compaction\, gene
  expression photocontrol\, synthetic biology and artificial cell systems t
 o evaporative assembly\, coffee-ring effect manipulations and light-driven
  microfluidics.” He recently got the rare and prestigious Mergier-Bourde
 ix award (only one award every four years in chemistry\, biology or medeci
 ne) from the French academy of science\, for the “exceptional originalit
 y and diversity of his works”. His current research interests include me
 tafluidics\, coffee-ring diagnostics\, dynamic DNA nanotechnologies and so
 ft synthetic biology.\n
