Research interests

My PhD research is in determining the long-term ranging patterns and effects of habitat disturbance on the Sumatran orangutan population at Ketambe, Sumatra, Indonesia. Data for the project consists of that collected from 1976-2011, with the site having also been exposed to numerous incidents of illegal logging from 1988 onwards - which in addition to published and unpublished survey data, shall be supplemented with Landsat-based historical analyses to refine the location, time, and severity of habitat degradation throughout the research site.

Apart from establishing the home range parameters from this extensive dataset, the study will investigate how changes in habitat quality affect aspects of ranging, and if there are differences in how the critically endangered Sumatran orangutan (Pongo abelii) responds as compared to the endangered Bornean species (Pongo pygmaeus).
