Elizabeth Stacy (PI) – I have been fascinated by the origin of tree species ever since my first visit to the Peruvian Amazon decades ago.  As such, my research centers on the problems of population divergence and speciation of long-lived woody taxa.  For well over a decade, my studies have been based in Hawai’i, an evolutionary hotspot where ongoing species radiations allow examination of divergence at multiple stages of the speciation process.  New Face at UNLV: https://www.unlv.edu/news/article/new-face-elizabeth-stacy

Tomoko Sakishima – Ph.D. candidate: I became interested in plant evolutionary ecology and genetics when I joined the Stacy lab as an undergraduate and participated in workshops offered by the Core Genetics Facility at the University of Hawaii at Hilo.  After working as a molecular lab technician for a few years, I embarked on M.S. research with Hawaii’s Metrosideros polymorpha to assess how quickly tree populations can diverge across a long elevation gradient and which abiotic factors are likely responsible for diversification.  The focus of my dissertation at UNLV is a comparison of below-ground plant communication in early- and late-successional trees.
