Intereses de investigación:

a) Reproducción y desarrollo de invertebrados.

b) Biología intermareal.

c) Estresores ambientales.

d) Estrés oxidativo y metabolismo antioxidante.

e) Compuestos fotoprotectores.

Principalmente, nuestras investigaciones se han orientado a entender como fluctuaciones en las condiciones ambientales circundantes (UV-B, temperatura, niveles de oxigeno disuelto y salinidad) productos de los cambios de marea en un estuario pueden impactar la fisiología y aspectos reproductivos de organismos que en estos ambientes habitan. Así, respuestas celulares a través de la estimacion de daño oxidativo han sido contrastados con estrategias de defensa (e.g metabolismo antioxidante, compuestos fotoprotectores, etc…) para entender las estartegias que le permiten a este tipo de organismos consolidarse como especies dominantes de ambientes estresantes.
