Eligible to supervise Masters and PhD (as Co-Supervisor), but is currently at capacity - email supervisor to discuss availability.
I am a mathematician with an interest in the foundations and modeling of random phenomena. I studied my BSc in Actuarial Sciences and MSc in Mathematics at the National Autonomous University of México. Later on, I obtained my PhD in Applied Mathematics in 2019 from the Technical University of Denmark. In September 2018 started my position as an ARC Research Associate at The University of Adelaide, working with Giang T. Nguyen.
My interests lie in the area of probability and stochastic processes (applied and theoretical).
Recent projects include:
- Strong convergence of stochastic processes
- Stochastic differential equations in regime-switching environments
- Phase-type distributions and dependence in risk theory

During my PhD studies from 2015 to 2018, my scholarship was funded by the National Council of Science and Technology of México (CONACYT)
I have 7 years of experience as a Teaching Assistant of theoretical probability courses at BSc and MSc level in México and Denmark. In 2020, I was the course coordinator and lecturer of the course Applied Probability at The University of Adelaide.
