"I did my PhD at the University of Paderborn in Christine Silberhorn's group. In my thesis, I introduced a novel device, the so-called quantum pulse gate, which allows to address arbitrary TF modes of ultrafast quantum states. This device is one of the basic building blocks for several applications in QCUMbER.

"Currently I'm doing a post doc in Ian Walmsley's group at the University of Oxford, where I'm working on a caesium vapour quantum memory. Interestingly, the abstract theory that describes the memory is very similar to the quantum pulse gate. Both are special quantum mechanical beam splitters, which operate on TF modes of pulsed quantum states of light. I'm trying to transfer our findings from the quantum pulse gate to the memory, to realise a TF mode-selective storage of heralded single photons. This will facilitate the realisation of larger-scale synchronised quantum applications based on TF modes.

"I'm also interested in conveying our research to the general public. I took over responsibilities for the public outreach in QCUMbER, and hope to realise uncommon projects, which will make QCUMbER accessible to a broad audience."
