Domaines de recherches / Research Interest


Mes principaux interêts de recherche sont orientés vers le developpement d’une compréhension quantitative et mécaniste de la diagenèse précoce, des cycles du carbone et de l’azote, et de la dynamique du pH dans les sédiments marins et côtiers, et leurs réponses aux changements environnementaux. Ma recherche porte sur les sédiments permeables de la plateforme continentale, qui supportent un échange rapide d’eau interstitielle et une rémineralisation active.

My principal research interests are focused on developing a quantitative and mechanistic understanding of early diagenesis, carbon and nitrogen cycling, and pH dynamics in marine and coastal sediments, and their responses to environmental change. Permeable continental margin sediments are an important focus of my research, particularly as sites of rapid porewater exchange and active remineralization.
