In his Bachelor project, Robin has worked on the topic of entanglement dynamics in superconducting quantum bits.
For his Master project, he switched to statistical physics and stochastic processes. Specifically he has worked on generalized nonlinear integral models for time-dependent flows of viscoelastic liquids, using a combination of analytical and numerical methods.
