Biography

My research is in systematics, the science that names, classifies and determines the evolutionary relationships of living things. My laboratory explores all types of systematic problems ranging from the identification and circumscription of species, to the biogeography, evolution and phylogenetics of higher-level taxa. Although I work on all types of vascular plants, my primary focus is on species from the sedge family (Cyperaceae), a truly remarkable group characterized by its exceptional diversity (ca. 5000 species), varied habitats (deserts to rain forests), unusual cytology (2n = 12 to 112) and diverse biogeographical patterns (e.g., Gondwanan, bipolar). To explore such diverse subjects, my laboratory uses both traditional morphological and anatomical methods as well as modern molecular techniques (e.g., DNA Sanger and Next Generation Sequencing, microsatellites, fragment analyses, etc.). Visit my Homepage for more information on my research, publications, and advantages of working in my laboratory at the Center for Advanced Research in Environmental Genomics (CAREG).
