Global changes, environmental shocks, market forces and anthropogenic disturbances from harvesting to pollution are affecting natural populations in unprecedented ways and at different time and spatial scales. We use quantitative tools (from life history-based mathematical models to statistical analysis of empirical data) to investigate factors and processes affecting the dynamics of natural and harvested populations and we intend to use this knowledge to inform practical management.

The lab is currently focused on two main research lines, the first one is the dynamics of small-scale fisheries in a changing climate (and includes impact of ocean acidification on abalone fisheries in Baja California, shark conservation biology and the simulation of the effect of marine protected areas), the second is the control and elimination of infectious diseases with an important environmental component in their transmission cycle (most notably schistosomiasis in Western Africa, but we are working also on the dynamics of diseases of marine organisms).

Ultimately, our goal is to foster interdisciplinary knowledge and skills within our lab group with the aim of contributing to solve some of the major challenges society has to face, from the sustainable harvesting of renewable resources in a changing climate, to the control of infectious diseases of public health importance.

I am interested in recruiting graduate students. I am open to any applicants, but I am especially interested in applicants coming to Stanford with a robust quantitative background in either modelling, applied mathematics, population biology, disease dynamics, GIS, etc. Please send inquiries to deleo at stanford dot edu

General ecological models for human
subsistence, health and poverty

A first-of-its-kind effort that combines economic, ecological and epidemiological models. The lessons learned could inform interventions to lift people out of poverty.
