10 September 2012 New Junior Group Leader

Dr. Simon Wall

ICFO is happy to announce the arrival of new Nest Fellow, Dr. Simon Wall. Dr. Simon Wall joins ICFO as a Junior Group Leader with a research program that will focus on the study of new methods to manipulate and measure dynamics within solids using optical techniques on the ultrafast timescale.

Dr. Wall received his PhD from Oxford University, where he worked on Photo-induced dynamics in complex materials probed with femtosecond X-rays and few-cycle optical pulses. After his PhD, he worked as a postdoctoral fellow at the Fritz Haber Institute of the Max Planck Society, where his most recent research dealt with probing the structural changes resulting from the ultrafast insulator-metal phase transition in VO2 using coherent phonons.

The Ultrafast optical dynamics of solids group that Dr. Wall will establish at ICFO aims to manipulate the magnetic, structural and electronic states of matter with ultrafast electric fields to induce new properties when materials are driven out of equilibrium. In particular, he is interested in dynamics at the earliest timescales, where the coherence still plays a role, how changes in an ordered state propagate both spatially as well as temporally, and how the interface between excited and non-excited regions interact. These properties are measured in the time domain with a combination of linear and non-linear spectroscopic techniques that are performed in the lab, as well as experiments based at larger scale facilities around the world.

Welcome Simon!
