Curious & hands-on.
I am a postdoctoral researcher at the Institute of Fluid Mechanics and Heat Transfer at TU Wien, working on experimental multiphase flows with an environmental focus. I am drawn to research that connects rigorous physics to how we live with the natural world. Collaborators usually find me curious and hands-on: equally interested in the data, the instruments that produced them, and the people behind both.
My current project addresses CO₂ sequestration — how convection-driven mixing and long-term storage mechanisms in geological formations shape the safety, predictability, and viability of carbon capture and storage. Earlier work developed optical measurement methods for the full rotational dynamics of anisotropic microplastic fibres in turbulence, an essential ingredient for predicting microplastic dispersion in the oceans. Between BSc and PhD, I spent four years in R&D at the Bühler Group, combining experimental measurements with CFD and heat-transfer simulations to reduce the energy and material footprint of food-processing equipment.

My research investigates multiphase environmental flows: the turbulent transport of fibres, droplets, and dissolved species that drives several of the planet's most pressing problems. Three threads run through the work below — how anisotropic particles couple to turbulence (microplastics in the oceans), how convection sets the long-term fate of injected fluids (CO₂ in geological formations), and how to reduce emissions and energy consumption in industrial processes (Bühler food-line CFD).The common method is to build the instrument, take the measurement, and then close the loop with simulation, modelling, and learning.
