Professor
Prof. Dr. Hélène Seiler serves as a W1-W2 Tenure Track Professor at Freie Universität Berlin's Department of Physics and Principal Investigator for Project B11 within the TRR 227 Collaborative Research Center. She leads the Ultrafast Dynamics in Nanomaterials research group focusing on experimental studies of electronic excitations in nanoscale systems using coherent multi-dimensional electronic spectroscopy with 10-30 femtosecond resolution. Her research spans 2D materials (TMDCs, heterostructures) Nanotubes and quantum dots Molecules on 2D material platforms Photonic structures and metasurfaces Spintronic heterostructures with emphasis on identifying electronic disorder sources through microscopic energy dissipation channels. Current major projects include SFB 1772 on molecular heterostructures and the OPTIMAL research unit for optical control of quantum materials. Recent publications (2021-2025) reveal strong focus on ultrafast lattice dynamics in 2D materials, exciton-polaron interactions in perovskites, and quantum dynamics in nanocrystals. Her group develops specialized tools including a visible/near-IR coherent two-dimensional spectrometer with 15-fs pulses and angle-resolved spectroscopy for polariton imaging. Scientific leadership includes: Principal Investigator in TRR 227 'Ultrafast Spin Dynamics' Member of SFB 1772 on 2D material heterostructures Participant in OPTIMAL research unit Organizer of iRTG Joint Winter School She actively mentors doctoral researchers and teaches courses including 'Ultrafast Nanoscience' and 'Festkörperphysik' (Solid State Physics), with current team members including Trideep Kawde, Matteo Russo, and Pavel Trofimov. Her laboratory features custom-built instrumentation optimized for heterogeneous nanomaterials with micron-scale sample areas.
