My career began in Kenya, where I was a Research Scientist at the National Museums of Kenya (1993-2008). I have a BSc and MPhil from Moi University (Kenya), PhD from University of Reading (UK), and postdoctoral stints at Royal Botanic Gardens Kew (UK), Rutgers University (USA) and KU Leuven (Belgium). Since 2006, I have been teaching courses in Biodiversity and Evolutionary Biology and my research is predominantly on Angiosperm Systematics.

Ongoing research

i) Cyperaceae Systematics and evolution:

Cyperaceae is a cosmopolitan family with ~5500 species, in Southern Africa dominated by the tribes Cypereae, Schoeneae and Abildgaardieae. Together with collaborators in England (Prof Larridon, Dr Simpson), Belgium (Prof Goetghebeur, Dr Vrijdaghs), we have undertaken taxonomic & phylogenetic studies on the Cypereae. Significant contributions include revised taxonomy and floral ontogenetic studies.

On the Schoeneae, an austral temperate tribe, we have inferred phylogenetic relationships and biogeography, and revised the taxonomy of polyphyletic genera Costularia, Schoenus & Tetraria. These studies have involved collaboration at UCT (Prof T Verboom; postdoctoral fellow Dr T Elliott), Australia (Profs J Bruhl, K Wilson), England (Prof Larridon).

Genome evolution, especially polyploidy, is thought to influence speciation. Working with Prof P Bures (Czech Republic), we have screened representatives of the Cyperids, identifying several polyploidy events. The South African Schoenus clade have multiple ploidy levels, and these are associated with unique morphotypes. We are using multiple approaches (including next generation sequencing, ecophysiological trait analyses) to unravel patterns of polyploidy evolution and its influence of species ecology and biogeography.

ii) Wetland flora - floristic composition and biogeography patterns

Wetlands are unique habitats characterized by extended periods of waterlogging. Such habitats are occupied by plants that can tolerate inundation for extended periods or those bearing strategies to deal with inundation (e.g. ephemerals). In a heterogeneous landscapes, as observed in South Africa, disentangling patterns of wetland flora and drivers to the observed patterns is an important question. Working with Dr E Sieben (UKZN) we have mapped occurrence of plants in the wetlands and identified key parameters influencing the observed patterns. Further studies have investigated the use of wetland plants, especially papyrus in East African wetlands (in collaboration with Dr T Terer)

Among wetland plant lineages occurring in several continents, we have identified direction and timing of dispersal events. No single pattern is seen, with ‘out of Africa’ dispersal directly to Australasia ( Isolepis) or via Eurasia (Limosella) or Northern temperate origin then dispersal to Australiasia and Africa ( Callitrichae). This research, done in collaboration with Japanese postdoctoral researcher (Dr Y Ito) and co-workers, has also contributed to the taxonomy of several groups.

iii) Legumes: taxonomy, ecology & evolution

Legumes are a diverse lineage in the Cape Flora especially as post-fire weeds in the fynbos biome. Understanding patterns of occurrence of particular species has required research on the ecophysiology, community structures (including rhizobia association) and incorporated tools from ecology and evolution. This work has involved collaborators at UCT (Prof Stirton, Dr Chimphango), Stellenbosch (Dr Valentine), UK (Prof Sprent, Dr James) and cohorts of postgraduate students. Distinct legume assemblages occupy unique edaphic niches and utilize particular rhizobia types.

iv) Origin and evolution of the African savanna

The African savanna is characterized by C4 grasslands and woody assemblage frequently bearing spines. Using multidisciplinary approach, we have aspired to determine origin of unique traits associated with the savanna (spinesence, underground forests, elephant-foot tubers). These studies have involved collaborators in South Africa (Profs W Bond (UCT), M vdBank (UJ)), Canada (Prof J Davies), and UK (Drs O Maurin, P Wilkin).
