Her bachelor’s thesis discussed applying stochastic control in reinsurance strategies. Then, in 2016, she completed an MSc in Statistics and Computational Finance at the University of York, UK. Her master’s research was on the relationship between wellbeing and personal indicators like job status, marital status, income and gender, estimated by semiparametric mixed models.
