Researchers

Yves Auad (Paris)

Currently a PhD student interested in nano optics with high spatial resolution. During my master’s I worked in the development of a light collection mirror for a scanning tunneling microscope, while in my thesis I work using a similar system for light injection in a scanning transmission electron microscope.

Fatemeh Chahshuri is a PhD student in in the group of Prof. Nahid Talebi, at the Christian-Albrechts-Universität in Kiel. During her master studies at the University of Tehran, she synthesized and characterized nanocrystalline structures for applications in gas sensing in high vacuum conditions. Her PhD works concerns exploring light-electron interactions in an ultrafast electron microscope.

Armin Feist (Göttingen)

Armin Feist is a postdoctoral researcher in the group of Prof. Claus Ropers at the University of Göttingen and the Max-Planck-Institute of Biophysical Chemistry. His Ph.D. work focused on the development and application of Ultrafast TEM using coherent electron pulses.  He studied in Leipzig, Leeds and Göttingen, and his B.Sc. and M.Sc. theses addressed angle-resolved fluorescence in photonic crystals and laser-triggered field ion microscopy, respectively. His current research interests include nanoscale structural dynamics, optically tailored free-electron beams and the exploration of new instrumental capabilities in UTEM, with the vision of combining methods from ultrafast science with state-of-the-art electron microscopy.

Sangeetha Hari (Delmic)

Sangeetha Hari is an Applications Specialist at Delmic BV. She develops cathodoluminescence imaging and correlative light and electron microscopy for various applications. She obtained her PhD in 2017 from the Faculty of Applied Sciences at the TU Delft in “High resolution resist-free lithography in the SEM”. Her research experience includes gas phase electron-molecule collisions and  time of flight spectroscopy.

Alexander Lau (Paris)

Matthias Liebtrau (AMOLF)

Matthias Liebtrau is a PhD student in the group of Prof. Albert Polman at AMOLF in Amsterdam (the Netherlands). His research is focused on cathodoluminescence spectroscopy and low-energy photon-induced near-field electron microscopy to study coherent electron-light-matter interactions at the nanoscale. Matthias obtained his Master’s degree in Experimental Physics from the University of Bonn (Germany). He did his Master’s thesis research in the group of Prof. Stefan Linden, where he was working on experimental near-field characterization of plasmonic slot waveguides.

Kelly Mauser (AMOLF)

Kelly Mauser is a postdoctoral researcher in the group of Prof. Albert Polman at AMOLF (The Netherlands).  Her research focuses on using time-resolved cathodoluminescence to study nanoscale thermal transport, carrier dynamics, and coherent excitation processes.  She obtained her M.S. and Ph.D. in Applied Physics at CalTech (U.S.A.) in the group of Prof. Harry Atwater with thesis titled: “Resonant Thermoelectric Nanophotonics: Applications in Spectral and Thermal Sensing”. 

Masoud Taleb (Kiel)

Masoud Taleb is a postdoctoral researcher in the group of Prof. Nahid Talebi, at the Christian-Albrechts-Universität in Kiel. He obtained his PhD in materials science (2018) with the focus on development of nanoclusters and surface decoration of 2D materials for tuning their physical/chemical properties. His current research interests include strong coupling and plasmonics; studying exciton-photon and exciton-plasmon quasiparticle formations using Cathodoluminescence spectroscopy and angle-resolved mapping. He is additionally responsible for the electron microscopy lab and sample-preparation procedures.

Luiz Tizei – (Paris)

Luiz Tizei has a Bachelor in Physics (2005) from the Universidade Estadual de Campinas (UNICAMP, Campinas, Brazil). In 2011, he finished his PhD thesis at the same institute, under the supervision of Prof. Daniel Ugarte. He then joined the STEM group at the LPS (Orsay, France) for a post-doc between 2011 and 2013, during which he built a light intensity interferometer to detect single photon sources excited by fast electrons (cathodoluminescence) in an electron microscope. In late 2013 he left the STEM group and joined Kazu Suenaga at the AIST (Tsukuba, Japan) for a post-doc, during which he studied the physical and chemical properties of low dimensionality structures (single atoms, carbon nanotubes, atomic chains, 2D monolayers). He was hired at the CNRS in December 2014. His research is focused on the development of electron spectroscopy techniques and their application to nanooptics.
