I am a researcher at Informal Systems. Informal Systems is a core developer of the Cosmos Network software and protocols, a network of more than 266 interconnected blockchains that manages more than $69B in digital assets. Before joining Informal Systems I was a post-doctoral researcher at the IMDEA Software Institute in Madrid (Spain), where I worked with Alexey Gotsman. I was awarded a Ph.D. in Computer Science in July of 2018 from the Instituto Superior Técnico of the Universidade de Lisboa in Portugal and the Université Catholique de Louvain in Belgium where I worked with Luís Rodrigues and Peter Van Roy respectively.

Research interest

My research interests are in the design and implementation of provably correct distributed systems
