I study the evolution of Oxalis, focusing on breeding systems, biogeography, and bulb morphology.  My research emphasizes mentorship, and I care deeply about teaching science.

Bayes multistate reconstruction of ancestral geographic states of the American bulb-bearing oxalis

Figure from our recent Manuscript about the American bulb-bearing Oxalis: Bayesian 50% majority-rule consensus topology of combined nrITS and plastid datasets with Bayes Multistate reconstruction of ancestral geographic states. Pie graphs represent the distribution of posterior probabilities of ancestral states for each node. Colors represent the geographic coding (Red: Patagonia; Green: SE South America; Purple: Andes; Turquoise: Central America and southern Mexico; Orange: MTVB and north; Dark Blue: Africa). Provinces/departments/states are shaded on the maps based on the distributions of taxa represented by the phylogeny, based on data from Denton (1973) and Lourteig (2000). The widely-distributed weeds O. debilis and O. latifolia are not mapped.
