Research:
My general research interests include the systematics of the economically
important plant genera Rubus, which includes blackberries and raspberries,
and Mentha, including spearmint and peppermint. These groups have
long been considered taxonomically difficult due in part to polyploidy
(more than two sets of chromosomes), agamospermy (asexual seed
production) in Rubus, and hybridization.
I primarily
use molecular techniques, in particular DNA sequencing, to address
evolutionary
biology questions. These data can be used, for example, to infer
evolutionary relationships (phylogeny reconstruction), test hypotheses
of hybridization, examine biogeographic patterns, and consider
modes of speciation especially in polyploid taxa. I am also interested
in systematics of subfamily Rosoideae and the Rose family (Rosaceae),
tribe Mentheae of the mint family (Lamiaceae), and subfamily
Chloridoideae of the grass family (Poaceae). |
