About

I have been working as a PhD candiate on Functional Topological Systems in FACET since August 2023.

Main Supervisor: Professor Dennis Gerhard Meier

Co-supervisor: Professor Antonius T.J. van Helvoort

My main research goal is to explore the possibility of using ferroelectric domain walls as active electronic components. The research involves lithography, focused ion beam (FIB), and various scanning probe microscopy (SPM) techniques: conductive Atomic Force Microscopy (cAFM), Piezoresponse Force Microscopy (PFM), Kelvin Probe Force Microscopy (KPFM) etc.
