My dissertation research project addresses three broad but related issues; systematics, evolution of secondary woodiness and historical biogeography of the "Hedyotis-Oldenlandia" complex in the plant family Rubiaceae with special focus on Asian-Pacific lineages. The "Hedyotis-Oldenlandia" complex is a highly debated group in the Rubiaceae family with no strong consensus to date on its generic delimitations. By building a robust phylogeny using DNA and incorporating data from morphology and anatomy my project seeks to resolve the long-standing taxonomic debate within the group that has existed since the time of Linnaeus. In an attempt to build a well-resolved phylogeny in the large group such as "Hedyotis-Oldenlandia" complex (ca. 600 spp.), I am also investigating the issues of data combinability (e.g. of different gene regions from targeted sequencing method), effect of taxonomic sampling and missing data, and the resulting systematic bias in the phylogeny inferences under Bayesian framework.
A few lineages within Hedyotis-Oldenlandia complex (e.g. "Hedyotis" s.s.) are characterized by having secondarily derived wood, a narrow and montane distribution and a high species diversity compared to their herbaceous sister lineages. The other goal of my study is to understand the correlates of the secondary woodiness, differential rate of evolution and diversification between herbaceous and woody clades and ancient dispersal patterns of this group into and inside of tropical Asia.
