Research interest

I’m investigating phylogenetic community structure of a 25 ha plot forest dynamics plot in a mixed dipterocarp forest in Brunei Darussalam which is part of the Center for Tropical Forest Science - Forest Global Earth Observatory (CTFS-ForestGEO) network of plots using DNA barcoding. Based on DNA barcode sequences (rbcL and matk), phylogenetic relationships among the taxa will be reconstructed and used to calculate metrics of phylogenetic diversity (net relatedness index, nearest taxon index) to determine whether species are assembled into local communities at random or if they are more closely (phylogenetic clustering) or more distantly (overdispersion) related than expected by chance.

Further, I’m interested in the phylogenetic relationships of the tropical tree family Dipterocarpaceae, especially in the large subfamily Dipterocarpoideae which is distributed in Southeast Asia. Here, we conducted phylogenetic analysis using plastid DNA sequences included most genera of the subfamily Dipterocarpoideae from different parts of Asia (Sri Lanka, Thailand, Brunei), as well as individuals of the other subfamilies Monotoideae and Pakaraimaeoideae. The topologies of the phylogenetic trees provide new insights into the genus Shorea of Dipterocarpoideae, which is not monophyletic. We will use RAD sequencing for further investigations of this genus.
