      Research interests:

      I am working on electronics and mechanics of the Belle II Silicon Vertex Detector.

      This includes novel approaches such as lightweight compound materials, a new readout concept of double-sided silicon detectors as well as applying a digital filter for signal improvement or an artificial neural network for feature extraction - both in FPGA firmware.
