I studied Physics and Astrophysics at the Universidad Complutense de Madrid (Spain) and the Université de Liège (Belgium). In 2002 I received the PhD degree at the Universiteit van Amsterdam for a research on Anderson localization of light. I worked as postdoctoral researcher at the RWTH technical University in Aachen (Germany) from 2002 until 2005, working on THz photonics and plasmonics. In 2005, I become project leader (tenure tracker) at the FOM Institute AMOLF group and at Philips Research to set up the group Surface Photonics working on nano- and THz photonics. In 2010 I was appointed as part-time professor at the Eindhoven University of Technology (TU/e) and group leader (tenure scientist) at AMOLF. In 2015 we moved the group to DIFFER and I became full-professor at TU/e.

I joined the Photonics for Energy group in September 2014, following graduate studies in femtosecond multidimensional spectroscopy at the University of Toronto (Canada) under the supervision of Prof. R.J. Dwayne Miller. My thesis work centred primarily on the dynamics of molecular excitons in prototypical light-harvesting systems, and coherent control of photochemical reactions using shaped laser pulses. Here at DIFFER my focus has been split between studying emission and transport properties of organic molecules coupled to plasmonic nanoparticle arrays, and terahertz spectroscopy and microscopy of photonic structures in the far-infrared. In my free time I enjoy cooking, ice-hockey, and homebrewing!

I completed in 2011 my Master thesis on optics at the Fudan University (China). The same year I joined Prof. Thomas Ebbesen’s group for a PhD research at the University of Strasbourg. During the PhD until 09/2015, I have mainly worked on strong light-matter coupling, exploring how this coupling can affect the molecular and material properties. Currently, I work at the group of Photonics for Energy as a Post-doc, focusing on strong coupling with 2D materials and investigating its fundamental consequences.

I joined the group of Photonics for Energy as a postdoc from August 2016. My current research focuses on tailoring emissive properties of quantum emitters coupled with plasmonic arrays and developing active plasmonic devices. Prior to Differ, I studied Engineering Physics at Vietnam National University, Hanoi and received master degree (Materials and Devices) in a joint French-Vietnamese program. During my PhD, I worked with Dr. Aloyse Degiron at Institut d'Electronique Fondamentale to investigate the synergy of metamaterials and film of colloidal quantum dots for a new generation of optoelectronics.

I started in the Photonics for Energy group at DIFFER in April 2016 after doing a Master in the affiliated PSN group at the Eindhoven Univerisity of Technology. My master graduation project was focused on the application of semiconductor nanowires for use in photovoltaic solar cells. I'm currently working on strongly coupled systems in the Thz regime. In the free time I like do sports: running and field hockey, and one of my passions is traveling.

Prior to joining the group Photonics for Energy at DIFFER as a PhD student, I received my bachelor degree in Materials Science and Engineering from Sharif University of Technology in Tehran (Iran). I continued my studies in master degree at École Polytechnique Fédérale de Lausanne (Switzerland) in Materials Science and Engineering, with the orientation of semiconductor and optoelectronics materials. I did six-month internship at Philips Research Laboratories in Eindhoven (The Netherlands) at the department of Photonics Materials and Devices, where I worked on plasmonic metasurfaces for solid-state lighting. My research at DIFFER mainly involves studying strong light-matter interaction in proximity of resonant metallic nanostructures and investigating the nonlinear behavior of such systems at room temperature.

In May 2017 I joined the group Photonics for Energy at DIFFER. The project I do focusses on exciton-polariton transport in organic semiconductors.
Before coming to Eindhoven I studied applied physics at the University of Groningen, where I did my master graduation project in the Photophysics and Opto-Electronics group about water splitting by organic-inorganic hybrid photocathodes. During my master I did an internship at Polyera Corporation in Chicago about the influence of molecular conjugation length on charge transport in organic electronics. In my free time I like to play the bass.

I started my master graduation project in December 2016 at DIFFER and PSN group at Eindhoven University of Technology.
Before I started at DIFFER I was in Copenhagen for an internship and received my bachelor degree from Eindhoven University of Technology.
In my free time I enjoy cycling and reading.

I am an intern at DIFFER where I study the properties of TMDs since September 2017. My major is applied physics at Saxion applied University in Enschede. I have done an internship in radiotherapy before and I have spent my last semester on a feasibility study of the production of biogas and biodiesel from algae. I currently enjoy working at DIFFER, living in Eindhoven, cycling, running, swimming and chatting with friends.

I am a fourth-year Chemical Physics student from the University of Edinburgh carrying out a year-long internship at the Photonics for Energy group. My project here focuses on transition metal dichalcogenide monolayers. Last summer I undertook an internship at the Basque Center for Materials, Nanostructures, and Applications studying polymer-ionic liquid composites for the development of ionic exchange membranes. In previous summers I worked in the Polymerization Processes group at Polymat, the Basque Center for Macromolecular Design and Engineering. In my free time I write and edit for my university's science magazine (EUSci) and am actively involved in the Edinburgh Debates Union. I also enjoy reading, traveling and discovering new foods.
