Biography

Laurens Siebbeles is a prominent researcher in the field of Opto-electronic Materials. His studies focus on excitons and charge carriers in organic materials, inorganic quantum dots, and nanorods, as well as two-dimensional materials. His work includes the detection of excitons and charges produced by laser pulses via optical microwave and terahertz conductivity measurements across femto- to milliseconds timescales. He has conducted experiments exploring the quantum mechanical nature of exciton charge decay and recombination processes. Siebbeles studied chemistry at VU University Amsterdam and obtained his PhD at the FOM Institute for Atomic and Molecular Physics in Amsterdam, where he investigated quantum interference effects in molecular photodissociation. He further developed his career as a postdoctoral researcher at the University of Paris Sud before joining TU Delft in 1994. At TU Delft, he became an honorary Antoni van Leeuwenhoek professor in 2001 and has served on the Editorial Advisory Board for the Journal of Chemical Physics. Throughout his career, he has actively engaged in organizing and participating in (inter)national seminars and conferences.
