I grew up in Minas Gerais, Brazil—home to the world’s best food (source: my very unbiased palate). I double-majored in Mathematics and Statistics at the Universidade Federal de Uberlândia, in a region famous for exceptional coffee. While in Uberlândia, I worked in banking as a pricing analyst on treasury products and derivatives and completed an MBA in Finance. I then moved to Belo Horizonte—proudly boasting the most bars per capita—to earn a master’s in Statistics at the Universidade Federal de Minas Gerais. Life’s next plot twist took me to Saudi Arabia, where I completed my Ph.D. at King Abdullah University of Science and Technology, a one-of-a-kind campus on the Red Sea.

Research Interests

My research is driven by curiosity about the complexity of counting phenomena and rare events. This has led me to study discrete-valued time series and extreme value theory. I am particularly concerned with the increasing frequency of rare climatic events and financial crises, which were once considered extraordinary. More recently, the rise of generative artificial intelligence has sparked my interest in its applications to statistical education.

Fun Fact

Card-carrying Star Wars nerd: I’ve watched every film, series, and animations, read most of the canon, and logged too many hours in the games to admit. Technically a cyborg: I’ve got two screws in my right ring finger—courtesy of the “efficient” U.S. healthcare system.
Football hero: Ronaldo “Fenômeno.” (Yes, football. Not soccer.)
