Evolution of polyploid complexes using Antennaria (Asteraceae: Gnaphalieae) as a model
group. I am especially interested in the use of molecular techniques to study genome
evolution in young naturally occurring polyploid groups
Systematics, evolution, and phylogeny of the Asteraceae (sunflower family) with focus
on the tribe Gnaphalieae. The Gnaphalieae (paper daisies or everlastings) are a group
of sunflowers that have their greatest diversity in Australia, followed by Southern
Africa and South America and are poorly represented in the northern hemisphere.
Phylogeny and Systematics of the orange subfamily Aurantioideae (Rutaceae), with special
interest in determining the origins of the major Citrus cultivar groups using molecular
cytogenetics and molecular markers.
Utilization of wild relatives of cultivated plants in plant breeding programs for
Forensic botany, especially the use of micromorphology and molecular techniques in
