RESEARCH INTERESTS:
My research has focused on the evolutionary relationships of the pteridophytes as indicated by the fossil record and its relationship with extant pteridophytes, with the ultimate goal of documenting times of appearance of groups and the role of pteridophytes in the environments of the past. The suggested phylogenies which best stand the tests of time are supported by fossil evidence. My work has emphasized the ferns of the Cretaceous Age using the local Potomac Group and the Dakota Group for much of my data. Much of the work is now revisionary due to improved techniques of analysis such as electron microscopy and computer analysis of characters. Gradually this work is leading to a view of more primitive families in the lower Cretaceous probably in the role of ground covers followed by newer families in the later Cretaceous in a less dominant position in the environment. Recent information from molecular research should be integrated with the morphological and paleobotanical information to produce more robust phylogenies.
