He graduated in Biological Science from the Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, with the degree of Licenciate in Biology (1988) and he obtained his Ph.D. degree in the Biology Department, McGillUniversity in Canada (1994).

His general field of scientific interest is aquatic ecology, and within this general area he specializes in aquatic microbial ecology and biogeochemistry. The research he carries out focuses primarily on two major aspects: 1) The magnitude and regulation of bacterial metabolic activity and carbon metabolism, and their links to microbial diversity in natural aquatic ecosystems, and 2) more general problems in aquatic ecology, such as organic matter processing and flow, whole-system metabolic balances, factors affecting green-house gas production in aquatic ecosystems, and large-scale patterns in ecosystem metabolism.
