Background and activities
I am a PhD candidate in the functional materials and materials chemistry (FACET) research group. My research topic is ferroelectric tetragonal tungsten bronzes. I have made ceramic pellets and powders of various chemical compositions that crystallize in the tungsten bronze structure. Characterization methods I have used include diffraction techniques (powder XRD, monochromatic XRD, PDF), electrical characterization (dielectric spectroscopy, piezoresponse measurements), and temperature-dependent measurments (HT-XRD, temperature dependent dielectric spectroscopy, dilatometry, DSC, in-situ PDF). At the moment I am working mainly with DFT. From April to September 2019 I visited the group of Prof. Dr. Ulrich Aschauer at Universität Bern to learn more about their methods. I am grateful for the support from I. K. Lykkes fond 2019 which made this exchange possible.

I started in the 5 year integrated master's degree programme in nanoengineering at NTNU fall 2011. In my third year I chose nanotechnology for materials, energy and the environment as my field of study. In my fourth year, I travelled to UC San Diego, where I took graduate courses in physics, electronics, and nanoscience. My master's thesis was submitted in june 2016, at the department of materials science and engineering. The topics of the thesis were ceramic powder synthesis and processing, various XRD characterization methods, and dielectric spectroscopy applied to SBN, a ferroelectric tetragonal tungsten bronze.
