I am an ecologist and geneticist, and specialise in tropical forest trees, their reproductive ecology and the importance of forest genetic resources for resilient landscapes.
Currently leading Bioversity International’s cross-cutting research team, I work on conservation and sustainable use of socio–economically and ecologically important trees and their genetic diversity. I am also Group Leader in Applied Molecular Ecology, in the Department of Environmental System Science, ETH Zürich, Switzerland.
I lead research programmes across Southeast Asia, Latin America and Africa and the Safeguarding Forest Genetic Resources Cluster of CGIAR’s Research Program on Forests, Trees and Agroforestry.

Dipterocarp forest of Borneo
Most of the forests of Borneo are lowland dipterocarp forest and we are looking at how these trees reproduce and move their pollen and seeds around. We work in two major forest reserves in Borneo, Kabili Sepilok Virgin Jungle Reserve and Danum Valley Conservation Area, both in Sabah. We also work on a range of the most threatened dipterocarps in Sabah in collaboration with colleagues at the Forest Research Centre, Sabah Forest Department.
Supporting sustainable supply of Brazil nuts
Our research is aimed at gathering evidence to support sustainable supply chains of Brazil nuts from Peru to Switzerland. A joint project of ETH Zurich, CIFOR and Bioversity International, and is supported by the World Food System Center. We officially collaborate with the Peruvian organizations IIAP, UNAMAD and PROFONANPE.
Trees for Seeds
Using the right mix of native trees in forest restoration is essential. Obtaining seed from the appropriate sources of the right mixtures of tree species to achieve restoration objectives presents an enormous challenge. Seeds of most native tree species are currently not sufficiently available in nurseries.
To ensure resilience of restored ecosystems, planting material must be adapted to the restoration site and contain sufficient genetic diversity to adapt to future conditions.
