Abstract: I will explain how tropical degenerations and birational specialization techniques can be used in rationality problems. In particular, I will apply these techniques to study quartic fivefolds and complete intersections of a quadric and a cubic in $\mathbb{P}^6$. This is joint work with Johannes Nicaise.
