Understanding the structure of entanglement in quantum states prepared in experiments can be quite tricky. I come up with methods and measurement schemes that utilize the limited tools and readout at hand to deliver new insights on a microscopic level. My efforts up until now have been focused on ultracold quantum gases, but I now also start working on photonic systems. Furthermore, I am also interested in driven many-body quantum systems out of equilibrium. In particular, I study the stability of long-range order in space and time using numerical methods.
