Frédéric Vrins
Professeur
Frédéric Vrins est titulaire d'un master Ingénieur Civil électro-mécanicien (orientation mécatronique) délivré par l’École Polytechnique de Louvain (UCLouvain). Il y réalise également son doctorat, évoluant au sein du Machine Learning Group. Il obtient son PhD en 2007. Sa thèse porte sur le traitement adaptatif du signal et, plus précisément, sur des techniques de séparation de signaux avec des applications biomédicales. Il s'intéresse en particulier au filtrage des signaux ECG fœtaux de ceux de la mère enregistrés de manière externe à l’aide de techniques non invasives. Par la suite, Frédéric rejoint le secteur bancaire où il passe 7 ans en tant que Front Office Quant (Senior Expert), travaillant dans la salle des marchés d’une grande banque européenne. Il est alors chargé de développer des modèles mathématiques de tarification et de couverture liés aux produits dérivés sensibles au risque de crédit (CDS, CDO, CVA, etc). Depuis 2014, il est professeur titulaire de Finance Quantitative à temps plein au sein de la Louvain School of Management (UCLouvain), où il coordonne la majeure Financial Engineering depuis sa création. Il est membre du Louvain Institute for Data Analysis and Modeling in economics and statistics (LIDAM) et dirige le centre de recherche Louvain Finance (LFIN) depuis 2019.
Le domaine de recherche de Frédéric sont les mathématiques financières (finance stochastique) et, plus spécifiquement, la modélisation du risque de crédit. Il est éditeur associé de plusieurs revues, en particulier Regards Economiques (revue des économistes de l'UC Louvain), Risks et Statistical Methods and Applications (journal de la Société Italienne de Statistiques). Il est Professeur Vacataire à l'EM Lyon (France) et Professeur Affilié à HEC Montréal (Canada).
