About me

Hi! My name is Arsene-Brice Zotsa-Ngoufack and I'm a PhD in mathemactics. I did my Ph.D at Aix-Marseille Université/INRAE in France under the supervision of Raphael Forien, Etienne Pardoux and Raoul Ayissi. I studied from 2013 to 2019 at the University of Yaoundé I in Cameroon, where I obtained a Master's degree in complex analysis under the supervision of Professor Edgar Tchoundja. Then, during the academic year 2019-2020, I did a Master's degree in Probability-statistics applied to life sciences at Université Félix Houphouet Boigny d'Abidjan Cocody (M2PSAV). For this master's degree, I did my intership at INRAE in France under the supervision of Raphael Forien and Etienne Pardoux.

I defend my Ph.D on stochastic epidemic models with varying infectivity and waning immunity: Functional Law of Large Numbers, Functional Central Limit Theorem's. Weighted norm inequalities in the variable Lebesgue spaces for the Bergman projector on the unit ball of   Cⁿ, [Thesis,slide]

I am currently a postdoc fellow at Université du Québec à Montréal under the supervision of Hélène Guérin and Arthur Charpentier working on stochastic epidemic models in relation to actuarial science issues. I am also working on Backward stochastic differential equation and generative AI.
