CURRENTLY RECRUITING GRADUATE STUDENTS Conservation, theoretical ecology

2003 – Ph.D., Stanford (Biological Sciences)
2000 – Ph.D., James Cook (Mathematics)

Research in our lab group examines how ecology and socioeconomic sciences can be integrated more effectively to inform conservation strategies and the management of natural resources. Our approach is highly interdisciplinary and integrates mathematical modeling, statistical analyses, GIS, ecological field surveys, socioeconomic data, and other approaches. Our research aims to inform both biodiversity conservation strategies and the management of ecosystem services (benefits nature provides to people) and often involves close collaborations with NGOs, public agencies and for-profit companies.
