I am largely interested in conservation biology, via mostly theoretical approaches, motivated by the need to understand interplay between ecological and socioeconomic dynamics. I am also interested in general topics of theoretical ecology including macroecology and population dynamics. My current research projects include predicting the effect of marine protected areas, ecosystem-based fisheries management, and developing ecosystem model that provides ecological information across spatial scales.
