What I bring to a team

Ideation round at the TUM Innovation Sprint: how might suburban residents get a car without owning one?
  1. I translate between clinic and code.

    At LMU University Hospital I sit between paediatric surgeons, external experts and the engineering side. I turn what clinicians need into a model, a data pipeline and an annotation tool that 50+ clinical experts actually use.

    What that looks like
  2. I have prepared a fundraise.

    As founder’s associate at the climate-tech startup SolarMarkise I co-wrote the information memorandum, built the valuation model and set up the data room for the pre-seed round.

  3. I pick up the organising.

    As Head of Innovation at TUM.ai, I led the student initiative’s interest groups and gave them what they needed to build: network, funding and more. At my residence hall, Ludwigskolleg Munich, I represent the students.

  4. I ask what technology does to people.

    My essay “Is AI the Anti-Socrates?” won second place at the Salzburg Philosophy Olympiad and made me one of 28 students, out of 1,807, nominated for the national round. I still read a lot on technology policy and human-AI interaction.
