Lewiner.

Deux doctorats, professeur, quinze ans chercheur en mathématiques, désormais à la tête des données et de la bioinformatique dans l'industrie. Les après-midis de pluie, quelques petites applications créées avec mes enfants.

parcours

Je suis un dirigeant titulaire d'un double doctorat avec environ vingt ans d'expérience partagés entre la R&D de pointe et le déploiement de solutions concrètes. Je dirige actuellement l'IA et la bioinformatique pour la conception de vaccins de nouvelle génération chez Ceva Santé Animale.

Avant cela, j'ai contribué au développement de BCG Gamma (aujourd'hui BCG X) depuis ses débuts, et pendant quinze ans, j'ai été chercheur et professeur de mathématiques à la PUC-Rio, travaillant en géométrie algorithmique et topologie, théorie de Morse discrète, traitement de la géométrie, modélisation de réservoirs et mécanique des fluides numérique. J'ai été élu membre affilié de l' Académie Brésilienne des Sciences.
