DESCRIPTION:Prof. Helena Swygenhoven\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 provide theref
 ore interesting synergies between experimental and computational material 
 science. Coupling these two offers new means to elucidate long-standing cr
 itical questions and provide new mechanistic insight into the deformation 
 and fracture of metals.  With the upcoming free-electron lasers like Swis
 sFEL\, providing very intense and tightly focused beams of x-rays with pul
 ses as short as 10 femtoseconds\, the timescale of atomistic based computa
 tional methods can be reached\, opening the pathway to a new generation of
  synergies.\nBio: Helena Van Swygenhoven studied physics in the Free Unive
 rsity of Brussels and obtained her PhD degree in physics from the Central 
 Jury in Belgium on radiation damage in materials.  After a professional b
 reak for motherhood\, she joined the Fusion Technology Division at the Pau
 l Scherrer Institute in Switzerland with a Marie-Heim Vögtlin stipendium 
 from the Swiss National Science Foundation. She heads now at PSI a researc
 h group focussing on structural and mechanical properties of metals. With 
 her group she designed a series of insitu methods at the Swiss Light Sourc
 e and the Swiss Neutron Spallation Source allowing following the footprint
 s of microstructures during deformation or thermal treatments. The strengt
 h and uniqueness of her research group lies in the synergies produced betw
 een these insitu methods and computational material science. She recently 
 received an ERC advanced grant for studying deformation mechanism during i
 nsitu non-proportional multiaxial loading.
