About myself

After studying chemistry for 5 years at Bonn University, I graduated in 2011. I wrote my master thesis on the in situ investigation of electrochemically generated radicals via EPR-spectroscopy in the group of Maurice van Gastle.

For my PhD study I changed to the group of Helmut Baltruschat (also Bonn University), where I did fundamental research on the Oxygen Reduction and Oxygen Evolution Reaction in organic and aqueous electrolytes. Aside from standard techniques of electrochemistry I used Differential Electrochemical Mass Spectroscopy (DEMS), electrochemical Quartz Crystal Microbalance (eQCM) and Photoelectron Spectroscopy (XPS, AES). I obtained my PhD degree (Dr. rer. nat.) in 2017.

Since 2016 I work in the group of Marc Koper (Leiden University). In my first project as a PD, I investigated the electrochemical hydrogenation of carbonyl compounds at single crystal electrodes. In that phase I learned how to combine Surface Enhance Raman Spectroscopy (SERS) with electrochemistry. In 2018 I changed to the ARC CBBC project.

As a researcher, I am passionate about

The inexhaustible capacity of the human mind to experience curiosity for the most useless stuff.

At the moment I work on

The project I work on aims to create fuel molecules by reacting water and CO2 using electricity. My task is to set up a DEMS system at Leiden University. This system can monitor the evolution of gaseous products formed in the course of electrochemical CO2 reduction in situ, online and under mass transport control. Furthermore, I will device a method that allows the detection and quantification of minor amounts of CO (28 amu) in the presence of large quantities of CO2. This is a challenge as CO2, due to its fragmentation pattern, creates not only a very high (hence noisy) but also a shifting baseline on mass 28.

Within ARC CBBC, I wish to accomplish

My effort on method development will be futile if not utilized in someone else’s research on CO2 reduction. Hence, I wish for collaborations with other project members that should lead to publications with scientific significance.
