Background and activities
The overall goal for my PhD project is to develop a biocompatible, lead-free piezoelectric material for sensors to be used in vivo. More specificly, my PhD focuses on a novel, aqueous synthesis route for K0.5Na0.5NbO3 (KNN) thin-films, and the integration of these thin films in biomedical applications. I focus on tuning the chemistry of the synthesis to improve the functional, mechanical and bio-interactive properties of the thin films.
My expertise is aqueous synthesis of functional ceramics, both as bulk materials and at the nano scale. I currently work with functional perovskites (ferroelectric materials), but I also have experimental experience with hexagonal manganites. I have good experience with the following synthesis and characterization techniques: Aqueous sol-gel synthesis of ceramics, clean room synthesis of thin films, X-ray diffraction (XRD), thermogravimetric analysis with mass spectroscopy (TGA-MS), Fourier transform infrared spectroscopy (FTIR), scanning elecron microscopy (SEM). My research is mostly conducted in a wet chemistry laboratory and NanoLab (cleanroom) at NTNU.
I have a master's degree in materials science and engineering from NTNU (2016). My master's thesis explored the effect of donor doping of hexagonal rare-earth manganites (h-RMnO3, R = Y, Dy) on the oxygen absorption properties of these materials.
On my free time, I enjoy outdoors activities like hiking, fishing and hunting.
