Biography

Shunsuke Sasaki currently works at the Jean Rouxel Materials Institute in Nantes (IMN) as a permanent researcher affiliated to the French National Centre for Scientific Research (CNRS). He earned his bachelor’s degree in polymer chemistry from the Tokyo Institute of Technology in 2014. He continued his studies in organic and polymeric materials at the same institute and completed his Ph.D. research on the design of fluorescent molecules in 2017, under the supervision of Dr. Gen-ichi Konishi. Afterward, he decided to shift his focus to inorganic solid-state chemistry and worked as a JSPS postdoctoral fellow at Nantes University under the guidance of Dr. Laurent Cario and his co-workers at IMN until 2020. He conducted another postdoctoral research at the University of Oxford with Dr. Simon J. Clarke before being recruited by CNRS in 2022. His current research focuses on developing novel low-temperature reactions that enable the tailored design of inorganic solid-state materials with exotic 2D structures.

Ongoing research projects:

French National Research Agency (ANR) project - COBEDIT
“Covalent-bond editing by topochemistry of chalcogenide materials” Role: Coordinator

Activities in the research community

Biographie : 

Titulaire d’un Master en Matériaux Innovants et Systèmes Énergétiques, j’ai réalisé mon stage de fin d’études chez STMicroelectronics à Tours, où j’ai travaillé sur l’optimisation d’un procédé de gravure pour des capacités TaN/SiN/TaN. Actuellement doctorant à l’Institut des Matériaux Jean Rouxel au sein de l’équipe PCM, mes travaux portent sur le développement d’électrodes pour micro-supercondensateurs 3D, à l’aide des techniques de dépôt par pulvérisation cathodique impulsionnelle à haute puissance (HiPIMS) et sa variante enrichie l’e-HiPIMS. L’objectif de cette thèse est d’optimiser la structuration, la conformité et les performances électrochimiques des électrodes (TiN, VN/VOxNy) sur substrats 3D pour répondre aux besoins en stockage d’énergie à haute densité dans les systèmes miniaturisés.
