My lab focuses primarily
in the systematic study of plant phylogeny and evolution at different
taxonomic levels using a wide array of traditional and molecular techniques.
I am particularly interested in the family Cactaceae, in which I am currently
investigating aspects of reproductive biology and two key features:
1) the origin, phylogeny, and evolution of epiphytism,
2) the genetic and physiological basis of vivipary
and its ecological and evolutionary significance (click to see stages
of vivipary in Ferocactus
herrerae and stages of vivipary in Epiphyllum
3) reproductive biology in the Cactaceae (click here to see the sensitive stamens of O. polyacantha).
Visit the research section
of my website for more information on the questions addressed in the above
topics and my research program.
My laboratory has capabilites to support a wide range of research studies
in plant systematics. Note that previous graduate students and visiting
scholars have been engaged in the investigation of several aspects in
other plant families, e.g., Asteraceae, Commelinaceae, and Poaceae, as
well as the morphological and molecular characterization of arbuscular
I welcome applications from potential graduate students and visitor fellows
interested in aspects of plant biology and ethnobotany of temperate and
tropical plants as well as those interested in floristic and taxonomic
studies involving the Saskatchewan and/or Canadian flora. Do not hesitate
me for further information.
Students enrolling in Biology
323.3 "Plants Systematics & Evolution" should contact the
herbarium technician to learn the requirements of the project.
New course in Tropical Botany to be added
to the curriculum soon. Check our course
page for updates as they become available.
