Research Activities I’m currently a researcher of the CESIMAR - CONICET. I’m a member of Marine Mammal Laboratory where participate in several projects related to ecology and behavior of marine mammals. I’m studying dolphins’ populations, mainly the dynamics and social structure of groups, the population size, residency and migration rate of dusky dolphins in the North Patagonian gulfs, as well as their behavior and habitat use. The output of these researches is a set of management regulations for the dolphin-watching activities. Also I’m participated in a project on the study of the foraging dynamics and the transfer of toxins from plankton to the southern right whale

Actualmente soy Investigadora Asistente del CESIMAR – CONICET. Soy parte del Laboratorio de Mamíferos Marinos donde participo en varios proyectos relacionados con la ecología y el comportamiento de los mamíferos marinos. Principalmente estudio las poblaciones de delfines de los golfos Norpatagínicos, investigando mediante técnicas de fotoidentificación la dinámica y estructura social de los grupos, su abundancia, los patrones de residencia y migración, así como también el comportamiento y uso de hábitat. Además participo de un proyecto enmarcado en el estudio de la dinámica del forrajeo y la transferencia de toxinas desde el plancton a la Ballena Franca Austral
Research Region Southwest Alantic - Northpatagonic gulf of Argentina
