Anne Guilbert is an EPSRC Postdoctoral Fellow is the Department of Physics since July 2017. She obtained the title of Ingénieur in Materials Science from Grenoble Institute of Technology INPG (France) in 2009. The same year, she was awarded a Master of Science in Materials Science with honours from INPG (France) and TU Darmstadt (Germany). She was awarded a PhD in Physics from Imperial in 2013. In 2013-2014, she was holding an EPSRC Doctoral Prize Fellowship in Chemical Engineering at Imperial working in collaboration with Dr João T. Cabral. Between 2014-2017, she was a research associate in the group of Prof. Jenny Nelson.


 My research focuses on understanding the link between chemical structure and properties of organic semiconductors for solar energy applications with a particular emphasis on understanding how chemical structure and packing of the materials controls the material properties. When most of the studies in the literature focus on the phase behaviour of organic semiconductors, I am also studying the structural dynamics of organic semiconductors to further understand how structure and dynamics impacts optical and electronic properties using various neutron scattering techniques (diffraction, quasi-elastic neutron scattering, neutron spin-echo spectroscopy, inelastic neutron scattering) combined with density functional theory and molecular dynamics simulation.
