SYSTEMATICS & TAXONOMYAs we all know, systematics is a synthetic science that employs multiple lines of evidence to develop systems of nomenclature, classification, monographs, floristic inventories, and hypotheses of phylogenetic relationships. Focus of my research is the interface of systematics and evolutionary biology. I utilize a broad range of experimental data in investigating taxonomic relationships, phylogenetic patterns, modes of speciation and hybridization among flowering plants. My systematics and taxonomy interests follow:
1. Speciation in serpentine endemic plants
2. Taxonomy of Streptanthus (Section Euclisia, Cruciferae)
3. Interfertility among North American species of Silene and Lychnis (Caryophyllaceae)
4. Cytogenetics of interspecific hybrids
5. Cytotaxonomy of Silene and Phacelia.
