DESCRIPTION:Prof. Kislon Voïtchovsky\, Durham University\, UK\nLiquid mol
 ecules tend to behave differently at the surface of immersed solids compar
 ed to when in bulk liquid. This gives ‘interfacial liquid’ the ability
  to influence countless nanoscale processes\, from the self-assembly of mo
 lecules and ions\, to controlling local electrostatics\, molecular transfe
 r and in lubrication.\nUsing bespoke experimental approaches based atomic 
 force microscopy\, it is possible to map the equilibrium organisation and 
 local dynamics of liquids near surfaces with nanoscale precision. The resu
 lts\, complemented by computer simulations\, show an interplay between loc
 al molecular organisation and the emergence of mesoscale phenomena over hu
 ndreds of nanometres through group effect. On minerals and at biointerface
 s\, water-stabilised ionic condensates can remain in place for tens of sec
 onds\, dramatically altering the local electrostatics\, mechanical propert
 ies and self-assembly. Nanoscale chemical and structural singularities of 
 the solid can also affect the dynamics of the liquid and induce spatially 
 correlated motion with consequences for lubrication and diffusion in soft 
 and biological systems.\n\nBio: Kislon Voïtchovsky is currently a profess
 or in Soft Condensed Matter Physics at Durham University\, UK. He obtained
  is Masters in Physics from the University of Lausanne (now EPFL)\, follow
 ed by a PhD in Biological Physics from Oxford University\, and a 3-year SN
 SF postdoctoral fellowship in Materials Sciences at the Massachusetts Inst
 itute of Technology.\nHe returned to EPFL in 2010 as an SNSF Ambizione Fel
 low and started his career in Durham in 2013 with a tenure-track assistant
  professorship. His group’s research focuses on solid-liquid interfaces 
 at the nanoscale\, in particular the interplay between molecular-level eff
 ects and macroscopic consequences. The research is highly interdisciplinar
 y\, often combining cutting-edge new experimental techniques with computer
  simulations. Applications range from molecular self-assembly to nanolubri
 cation\, crystal growth\, ionic effects\, and biological interfaces.\n
