As a postdoctoral researcher at the MPI for Solid State Research in the group of Prof. Bettina Lotsch in Stuttgart, I am exploring the chemical space of hybrid organic-inorganic metal halides. My research focuses on understanding and controlling the unique properties of these materials, particularly how the lone pair expression leads to ferroelectric and luminescent properties.
Using a combination of advanced characterization techniques – including single crystal X-ray diffraction, powder diffraction, differential thermal analysis, and various spectroscopic methods – I investigate how organic cations can template both the electronic and structural properties of these hybrid materials. Currently, I also explore machine learning assisted approaches to investigate these templating effects. This systematic approach allows me to establish clear structure-property relationships and design materials with tailored functionalities.
Besides my research I am a member of the eConversion Graduate Program. From 2020 to 2022 I was a member of the student board, organizing educational and networking events.
