Areas of expertise
PhD in Nanotechnology and Optical Instrumentation, 2004
Johan obtained a PhD in Near-Field Optics in 2004 from the University of Technology of Troyes (France). He worked as a research and teaching assistant for one year in the same institution before being appointed as an Assistant Professor at Paris-Diderot University. His research focused on the mechanisms involved in Surface-Enhanced Spectroscopies (Raman, fluorescence). More broadly, he worked on the coupling of metallic nanoparticles with different molecular entities (photochromic compounds, liquid crystal, thermosensitive molecules). In 2017, he took research and study leave from Paris Diderot University to work at Victoria University of Wellington in the Raman Lab led by Eric Le Ru.
He is the author and co-author of 58 publications and one book chapter. He joined MSL in 2019 to work on research across Time and Length standards.
