Hello! My name is Miguel and this is my webpage. Since 2019 I'm a PhD student at ETH Zurich and my advisor is Rahul Pandharipande. Before that I did my bachelor's degree (finished in 2017) and master's degree (finished in 2019) in Instituto Superior Técnico, Lisbon. My master's thesis advisors were Miguel Abreu and Leonardo Macarini.

My research mostly concerns enumerative invariants defined using moduli spaces parametrizing some sort of geometric objects. Examples include Gromov-Witten theory, stable pairs, Hilbert schemes or moduli of stable bundles. Lately I've been particularly interested in formulating and understanding the Virasoro constraints on different moduli spaces of sheaf-like objects.
