Hello There!

I grew up in Mexico and had the chance to discover many different countries, many varied people, and many cultures. Since I was in high school I've been interested in Economics, Social Sciences and Mathematics. For me, Actuarial and Financial Sciences is where those three subjects overlap. Thus, I would like to deepen my mathematical skills to better serve the profession.

Today I'm doing an industrial thesis in applied mathematics at the Centre de Recherche en Economie et Statistique (CREST), the Institut de Mathématique de Toulouse (IMT) and Exiom Partners.

My supervisors

Caroline Hillairet (CREST) and Anthony Réveillac (IMT)

PhD Projects

Cramer-Lundberg and Hawkes (M1 internship)

Numerical estimation of the net profit condition and the ruin probability of a Cramér-Lundberg model where the counting process is a Hawkes process.

Multidimentional Marked Hawkes Risk Process : cumulants

Calculation of the first three cumulants af a risk processes where the losses (marks) have an impact on the intensisty of the counting process.

Multidimentional Marked Hawkes Risk Process : Stop Loss

Application to a Stop Loss contract, calculation of moments and correlations.
