DSC09783Rebecca L. Stubbs

Email: stubbsrl[at]
Using the non-model plant clade Micranthes (Saxifragaceae), Rebecca is investigating a number of evolutionary processes such as speciation, rapid diversification, and adaptation to alpine and Arctic climates. To address these questions, she has collected and sequenced ~150 plants and has analyzed over one terabyte of next-generation sequencing data. Her work has allowed her to master methods that utilize ecological niche modeling, ancestral character state reconstructions, and biogeographical, diversification, and dating analyses. In addition to her core research, she is also interested in outreach and has extensive experience in planning and executing fieldwork. Website

Interested in the evolution of underground storage organs (i.e., bulbs, corms, tubers, rhizomes, etc.) with a particular focus on bulbs (e.g., onions). Along those lines, his dissertation is largely focused on the evolution and biogeography of Ledebouria (Asparagaceae) a bulbous plant related to the hyacinth that can be found throughout sub-Saharan Africa as well as Madagascar, Socotra, Yemen, India and Sri Lanka.

Kevin is a Biology major and currently working with Cody on assessing the genome sizes and ploidal levels of Ledebouria (Asparagaceae).



Halle Marchese

Halle is working with Cody and helping to develop methods for microcomputed tomography (uCT scanning) of bulbous plants in order to study developmental and morphological differences. She is also using her interest in scientific writing to educate the public on the importance of bulbous plants as well as to promote their study.
