Our research is mainly motivated by granular materials and their dynamics, but we also take great interest in general fluid mechanics and hydraulics. We develop theoretical and experimental work to better understand these topics, always aiming for engineering solutions and applied models. So please take a look at the webpage for publications, current funding and present members.

25.09.2026 We said goodbye to three members of Grupular: Tomás Fuentes, Alexander Navarrete and Wladimir Vergara. Tomás will begin a PhD in the Laboratoire de Mécanique des Fluides de Lille Kampé de Fériet (LMFL) under the supervision of Martín Obligado. Alexander will also begin a PhD in the Laboratoire Matière et Systèmes Complexes (MSC) under the supervision of Mathieu Roche and Élisabeth Guazzelli. Finally, Wladimir Vergara leaves UAI after 9 years of commitment and hard work looking for new opportunities as Civil Constructor. We wish you all nothing but the best!
