My main research interests are primate ecology and primate conservation. My Ph.D. research utilizes bioacoustic techniques to study the Bornean gibbon (Hylobates muelleri). I am currently investigating the relative importance of geographic distance and ecological similarity as drivers of variation in the Bornean gibbon great call. I am also working to develop a technique to census and monitor gibbons that utilizes variation in their calls to identify specific individuals, a technique known as "vocal fingerprinting".
