I am eager to work towards a more sustainable world. My ph.d.-project is a part of MoZEES (Mobility Zero Emission Energy Systems), which is a FME (Centre for Environment-friendly Energy Research) focusing on developing battery- and hydrogen technology for transport applications. I am working on batteries, more specifically cathode materials, and will  focus on safety and thermal stability of these. As well as novel cathode materials, also some commercial materials will be tested and modfifyed to see if stability and/or performance can be improved. 

I use X-ray techniques to investigate how the materials behave, and I regularly visit synchrotron facilities such as the Swiss-Norwegian Beam Line (SNBL) at European Synchrotron Radiation Facility (ESRF) in Grenoble. Here I perform operando measurements to learn about the mechanisms in situ, investigating how the material changes as we charge and decharge the battery.

Background

After a year of studying maths at NTNU, I moved to Aarhus to study Nanoscience at Aarhus University. Here I specialized within catalysis and energy materials, and the title of my Master's thesis was "Metal Doped Nitrogenated Carbon Material as Electrocatalyst for CO2 Reduction".

Afterwords I was hired for 4 months as a research assistant at Aarhus University, working on growing polymer brushes on stainless steel to protect industrial heat exchangers from scaling.
