I deal with the development of a structured illumination microscope (SIM) for super resolution microscopy and the image reconstruction. For the latter Python and Matlab is used. As postdoctoral researcher it is also my task to take part in organization and management of our research group. (e.g. supervision of PhD students, management of resources and organization of purchases)

PhD topic: Optical Kerr Gate for Eliciting Axial emitter Profiles Gained Knowledge: running and maintaining femtosecond laser sources (oscillators, CPA systems, OPAs) Programming: LabView (system automatisation), Python (Data analysis) Teaching: Lab supervision (laser technolgies, laser based measurements, physical chemistry) System development: Z-Scan setups Optical gating setups (Kerrgates) for Fluorescence with (100 fs time resolution) Cavity Ring-Down setups suitable for industrial sale

During my work as a research assistant I prepared my PhD work.

In the framework of a post study internship, I worked as a researcher at the university of New Mexico. My task was to investigate the influence of the impact ionization in dielectric materials at the pre-ablation regime and the femtosecond time scale. Hence I dealt with running and maintaining femtosecond laser systems (both, oscillators and chirped pules amplifiers) as well as building complex optical setups.

At the Grintech company I worked on optimizing and manufacturing gradient lens based optical sensors.

I worked on testing a novel developed device for ophthalmologic examinations

Optics, Biophysics, Physics of soft condensed matter

In my studies, I dealt with general Physics, Optics and photonics and Laser technology
