Dale is a lifelong resident of Texas, whose early interest in botany originated on numerous trips to the family farm in Lavaca County (coastal plain of south-central Texas). It was there that he developed a deep love of the outdoors, and first took notice of the flora of Texas. Although his interests include the Cyperaceae and Juncaceae families; his true passion for botany is the lower plants. Dale’s M.S. thesis, Floristics and Biogeography of the Bryophyte Flora in the Big Thicket National Preserve, Southeast Texas, was the first comprehensive inventory of bryophytes in the Preserve since its founding in 1974.

In the broadest sense, his interests involve the systematics, ecology, and biogeography of the mosses, liverworts, hornworts, (bryophytes) and lichens.  Although this research is largely in Texas and the southern United States, he has made substantial collections in the northeastern and northwestern United States.  Additional opportunities to explore these groups have taken him on numerous trips abroad to Scotland, England, and Mexico.  

Specific bryological and lichenological interests include: 1) spatial and temporal distributions at local, regional, and global scales, 2) successional patterns and processes, 3) vertical distributions in tree canopies, 4) the structure and composition of communities, and 5) the biotic and abiotic parameters regulating the formation and persistence of communities.
