Damien Thiry research activities deal with the field of plasma polymerization. The objective is to enlarge the understanding at the fundamental level of the growth mechanism of functionalized plasma polymer films. His research philosophy is based on a multidisciplinary approach combining plasma diagnostic (mass spectrometry, optical emission and FTIR spectroscopies) and thin film characterization (XPS, ToF-SIMS). Furthermore, for a detailed understanding of the numerous reactions pathways taking place in the plasma, theoretical tools (e.g. DFT) are usually employed and correlated to experimental data. The understanding gained in this topic paves the way for a more efficient use of plasma polymers in important technological applications including the fabrication of biosensor, platform for biomolecules immobilization or cell proliferation. Recently, based on the expertise gained during his post-doc position, his research also focuses on the synthesis of nano-organized functionalized plasma polymer films.
