Thibault J.-Y. Derrien is a Prague-based computational physicist, research group leader, drummer and independent creative professional. His work at FZU and IT4I focuses on ultrafast laser–matter interactions and quantum modeling, connecting experimental insight with theory. Research topics include laser-induced periodic surface structures (LIPSS), graphene and high-harmonic generation. His work includes scientific publications, open research tools and datasets, and a granted European patent for ultrafast laser writing of regular surface structures. He also convenes Ultrafast Photonics, a research circle bringing together collaborators and emerging leaders.

Alongside science, Derrien performs jazz and electronic music on drums, with projects including the TAJE jazz quartet, Bludný proud and TCF. His site presents recordings and upcoming performances, as well as opportunities to hire him for drum lessons at all levels. He also offers mentoring, teaching, translation, editing and review services.
