Team leaders

The EBEAM team is composed of 8 electron microscopy groups in basic research and industry that represent a unique combination of instruments, knowledge and ideas.

Albert Polman (project leader) is scientific group leader at the NWO-Institute AMOLF in Amsterdam, and professor of photonic materials for photovoltaics at the University of Amsterdam. His research group studies light-matter interaction at the nanoscale to realize solar cells with ultra-high efficiency that can be made at low costs, designs optical metasurface to realize analog optical computing, and develops cathodoluminescence spectroscopy as a super-resolution imaging technique for nanophotonics.

Javier García de Abajo is ICREA Research Professor at ICFO, the Institute of Photonic Sciences in Castelldefels where he leads the Nanophotonics Theory Group. His research agenda includes the theoretical study of electron microscope spectroscopies, graphene and two-dimensional plasmonics, atomic collisions, quantum phenomena at the nanoscale, and various aspects of nanophotonics ranging from optical sensing to quantum friction.

Toon Coenen is business unit manager of the cathodoluminescence branch of Delmic (CL solutions) which is concerned with the development, production/service and marketing/sales of the cathodoluminescence system portfolio. He collaborates with various groups and customers around the world on cathodoluminescence related projects. Coenen has pioneered several novel CL imaging techniques.

Erik Kieft is a scientist and project lead in the Advanced Technology department of the Materials and Structural Analysis division at Thermo Fisher Scientific, and based in Eindhoven. He has a background in applied physics, in particular the modeling of electron/matter interactions at SEM energies. Currently Kieft is working on a variety of topics in integration of time-dependent beam manipulation techniques into electron microscopes. This includes laser-based UTEM, as well as (resonant) beam deflection for generation of ultrashort pulses (with TU Eindhoven).

Mathieu Kociak is research director at the solid-state physics lab (LPS), a join research unit between CNRS and Université Paris-Saclay. He is the scientific leader of  CHROMATEM, an ultra-high-energy resolution electron microscopy project, and director of the French electron microscopy excellence network (METSA). Kociak’s main research interests include the study of the correlations between the structure, and the optical and electronic properties of individual nano-objects, that he tackles through a combination of instrumental developments in electron microscopy, experiments on the STEM and theory of the electron/matter/photon interaction. He is currently working especially on nanooptics with fast electrons using EELS and nano-cathodoluminescence (STEM-CL).

Claus Ropers is professor of experimental solid-state physics at the University of Göttingen and director at the Max Planck Institute for Biophysical Chemistry. His research interests are ultrafast electronic, structural and spin dynamics in solids, nanostructures and at surfaces. Ropers’ group develops and applies new experimental techniques based on imaging and diffraction with ultrashort electron pulses, combining high spatial and temporal resolutions. In particular, this includes Ultrafast Transmission Electron Microscopy (UTEM) and Ultrafast Low-Energy Electron Diffraction (ULEED).

Nahid Talebi is professor of physics and director of the Nanooptics department at the University of Kiel.  Her research has been at the border of photonics and electron microscopy, contributing to both fields theoretically and experimentally. Talebi has developed theoretical and numerical techniques to simulate the interaction of electron beams with plasmons and light, and proposed several novel methodologies for improving electron microscopy techniques and to enhance the temporal resolution of ultrafast electron microscopes. She has also developed self-consistent numerical techniques to simulate the interaction of electron wavepackets with light and has pioneered the field of electron-light interactions beyond the adiabatic approximations.

Jo Verbeeck is professor at the University of Antwerpen. He is an expert in electron beam shaping and electron energy loss spectroscopy (EELS) for the analytical characterisation of materials down to their atomic scale. He has a deep interest in the fundamental description of physical processes taking place in a TEM as guiding insight to determine the ultimate limits and ways of approaching them. Verbeeck developed a programmable phase plate for electrons, bringing adaptive optics to electron microscopes as well as a novel coincidence setup to revolutionize EELS and EDX spectroscopy. He has experience in software development and has former training and job experience as an electronics engineer. He developed a proof of concept setup for wide field automated electron diffraction based on a modest SEM (JEOL JSM5100) tool available in the lab. He is the author of EELSMODEL, an open source program to quantify EELS spectra.

Wiebke Albrecht is a scientific group leader at the NWO institute AMOLF in Amsterdam. Her research is focused on energy and charge transfer processes and structure-property correlations of functional hybrid nanomaterials, combining optical and electron microscopy and spectroscopy on single nanoparticles. She is furthermore interested in laser-induced reshaping of single nano-objects as well as in situ electron microscopy to quantify 3D diffusion in single nano-objects. She functions as the scientific secretary for the ebeam project.
