Welcome to My Research Website

Thank you for stopping by! I’m just a humble turbulence wrangler at the German Aerospace Center (brace yourself: Deutsches Zentrum für Luft- und Raumfahrt—good luck pronouncing that without sounding like you’re in a movie). I specialize in turbulence and aeroacoustics, which is just a fancy way of saying I spend my time making air behave… or at least trying to.
Feel free to check out my research group’s page here for more turbulence-related adventures! 🚀
