Tim B van Driel
Lead Scientist, LCLS - Linac Coherent Light Source
BioTim van Driel is a Lead Scientist at the Linac Coherent Light Source (LCLS) within the SLAC National Accelerator Laboratory with over a decade of experience as a subject matter expert. His research focuses on ultrafast time-resolved chemical dynamics, and he is currently leading the development of the LCLS-II-HE Condensed Phase Chemistry endstation. His efforts span experimental design, precision instrumentation and diagnostics, detector improvements, and advanced analysis frameworks to capture the non-equilibrium evolution of complex chemical systems. By directing "molecular movies," his work aims to visualize and control the fleeting dynamics of structure, spin, and charge that dictate performance from isolated molecules to energy and quantum materials. Dr. van Driel leads the deployment and development of the Liquid Jet Endstation (LJE) at LCLS, a specialized platform enabling femtosecond resolution measurements of photochemical and solvation processes.
Increasingly, his work focuses on the intersection of ultrafast multimodal X-ray science and artificial intelligence. Dr. van Driel is pioneering the integration of AI/ML into complex experimental workflows from dimensional reduction, improved signal to noise as well as automated pipelines and cross experiment scientific insights. He is also a key member of the ISAAC pathfinder project to autonomously guide and accelerate scientific discovery in catalysis across multiple national laboratories, seamlessly combining massive multimodal datasets with advanced theoretical models.
He received his Ph.D. in Physics from the Technical University of Denmark and his M.Sc. in Nanoscience from the University of Copenhagen. At SLAC, he is also deeply involved in pursuing new scientific directions and engaging with the larger community as the Secretary for the Peer Review Panel (PRP) for Chemistry, Soft Condensed Matter & Disordered Materials (CSD) and as an LCLS Culture Champion. -
Koen van Greevenbroek
Postdoctoral Scholar, Earth System Science
BioKoen is a postdoctoral scholar at the Sustainable Solutions Lab, working with Ken Caldeira and Steve Davis. His current work involves developing a global food systems optimization model to study trade-offs and synergies between emissions and health. With a background in mathematics and interested in sustainability generally, he has previously worked on continental long-term planning of energy systems. During his PhD at UiT The Arctic University of Norway, he focussed in particular on near-optimal solutions and weather variability.
