Timothy K. Lowrey
Professor and Curator of the Herbarium

Tim Lowrey

Research Interests

The main focus of my research is on biosystematic and molecular studies of the Asteraceae in the southern hemisphere. Currently, I am involved in the following studies:
  • Evolutionary genetics of adaptive radiation in Tetramolopium (with R. Whitkus, Sonoma State University, California)
  • Molecular systematics of Tetramolopium and Vittadinia (with C. Quinn, RBG Sydney)
  • Biosystematic revision of the Pteronia (Asteraceae) in South Africa (with P. Herman, NBI Pretoria)
