About Me

In 2015 I started as a student in Applied Physics at the University of Twente. My bachelor was completed with a thesis in the Optical Sciences (OS) group: ``Towards Extracellular Vesicle Detection using Aluminum Oxide Micro Ring Resonators.'' The thesis focused on the characterization of an Al2O3 micro ring resonator as well as on extracellular vesicles for diabetes detection. 

During my master in Applied Physics, at the University of Twente as well, I further specialized in optics. I did an internship at ETC Solar, a company commercializing world's highest performance front contact technology for solar cells: effectively transparent contacts.
My master was concluded with a thesis in the Inorganic Materials Science (IMS) group: ``Free-Space Concentration of Diffused Light''. The thesis proposed a new strategy for diffuse light concentration using Luminescent Solar Concentrators. I presented my work at the OSA advanced photonics congress 2020 and was awarded 2nd prize for the student paper award.

In 2020 I started working as a PhD candidate in the Photocatalytic Synthesis (PCS) group, combining my interests in optics and photovoltaics. My focus is on studying the optical and photodynamical properties of patterned metal halide perovskite layers, using time-resolved photoluminescence and transient absorption.

My research is about correlating metal halide perovskite nano-/micropatterning to optical and photodynamical properties, using time-resolved photoluminescence and transient absorption microscopy, in addition to steady-state spectroscopic techniques.
