Research background

My area of expertise is the fabrication of nanoscale devices taking advantage of the spin degree of freedom. I pioneered original systems and concepts in the field of spintronics, evolving towards multi-stimuli devices, at the frontier between physics, materials science and chemistry.

When reaching the nanoscale, the possible dominance of quantum properties and the increase of magnetic gradient forces lead to new properties. I am interested in interdisciplinary applications of these concepts, in molecular or organic electronics, nanofluidics and (electro)chemistry.

Current Research

  • 2D electronic detectors: by using 2D materials as interface or electrodes, and taking advantage of their tunable doping, we investigate how it is possible to interface or detect a change of opto-electronic properties of adsorbed molecules, quantum dots, or nanoparticles.
  • Multi-stimuli devices: multiferroic systems have the advantage of possible control of their strain, electric and/or magnetic properties by optical means. These cross-properties opens new perspectives of multifunctionality or devices properties enhancement and control. Hybrid solid-molecular materials are also good candidates for building switching devices triggered by multiples types of stimuli.
  • Magnetic forces: reducing the size increases the magnetic gradient forces, making possible control of the solid liquid interface charge transfer properties (electrochemistry) or cargo transport control (nano and microfluidics). The aim is to take advantage of the mature concepts in spintronics and magnetism to provide new means to influence these properties at the interface.

Academic background

Education in Switzerland (PhD University of Lausanne 1991), with postdocs in Cambridge (UK) and EPFL (CH). I then took an Assistant Professor position in the USA (University of Nebraska) in 1997, tenured in 2002, and joined the University of Strasbourg as Professor in September 2005.

Key awards: PhD prize of the University of Lausanne (top 2%), NSF Career grant (1998), Adjunct Director of the NSF MRSEC Center (2000), Chaired Professor of the French Ministry (2005), Fellow of the University of Strasbourg International Studies (2014), Fellow of the Institut Universitaire de France (Senior, 2021)
