Research Emphasis

Dr. Brown is interested in all aspects of Bromeliaceae (pineapple family) biology, with phylogenetic studies being the core-focus of his research program. His students are exposed to, and generally utilize, a broad spectrum of techniques aimed at generating data sets (morphological, anatomical, developmental, molecular, cytological) appropriate for modern phylogenetic analyses. Field work is a vital component in all of these studies.   He is also interested in the biology of rare plants in the Rocky Mountain Region.

Current Research Projects

  • Taxonomic revision of the genus Catopsis (Bromeliaceae - Tillandsioideae).
  • Phylogenetic systematics of the genus Aechmea (Bromeliaceae).
  • Taxonomic revision of the genus Oönopsis (Asteraceae).
  • Generic-level relationships within Bromeliaceae subfamily Bromelioideae.
  • Protananas, a new Cretaceous-age fossil from NE Brazil.
