DESCRIPTION:Prof. Helena Swygenhoven\, IMX/EPFL\nNeutrons and Xrays allow 
 probing the dynamic behavior of microstructures through diffraction or 3D 
 imaging and this over length- and time-scales commensurate of deformation 
 and damage mechanisms at the mesoscale. Insitu deformation studies can pro
 vide therefore interesting synergies between experimental and computationa
 l material science. Coupling these two offers new means to elucidate long-
 standing critical questions and provide new mechanistic insight into the d
 eformation and fracture of metals.  With the upcoming free-electron laser
 s like SwissFEL\, providing very intense and tightly focused beams of x-ra
 ys with pulses as short as 10 femtoseconds\, the timescale of atomistic ba
 sed computational methods can be reached\, opening the pathway to a new ge
 neration of synergies.\nBio: Helena Van Swygenhoven studied physics in the
  Free University of Brussels and obtained her PhD degree in physics from t
 he Central Jury in Belgium on radiation damage in materials.  After a pro
 fessional break for motherhood\, she joined the Fusion Technology Division
  at the Paul Scherrer Institute in Switzerland with a Marie-Heim Vögtlin 
 stipendium from the Swiss National Science Foundation. She heads now at PS
 I a research group focussing on structural and mechanical properties of me
 tals. With her group she designed a series of insitu methods at the Swiss 
 Light Source and the Swiss Neutron Spallation Source allowing following th
 e footprints of microstructures during deformation or thermal treatments. 
 The strength and uniqueness of her research group lies in the synergies pr
 oduced between these insitu methods and computational material science. Sh
 e recently received an ERC advanced grant for studying deformation mechani
 sm during insitu non-proportional multiaxial loading.
