Biology of New World pitcher plants           

Since 2001 I have been involved, with Dr. Rob Naczi, the Arthur G. Cronquist Curator of North American Botany of the New York Botanical Garden (http://www.nybg.org/science/scientist_profile.php?id_scientist=105), in a long-term study of the species biology and phylogeny of the New World carnivorous plant family Sarraceniaceae.  With several other colleagues we have recently published a phylogeny of the group (http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0039291).  We are now examining the biology of the 11 species in the genus Sarracenia in North America, with an intent to provide further resolution of the phylogenetic relationships among these remarkable taxa.  Our approach uses nuclear, plastid and mitochondrial loci as molecular markers, for both phylogenetic and species-level investigations. 

I am also assisting Dr. Naczi in his investigations of several species groups in the sedge generaCarex and Rhyncospora.  My group’s role is to generate nucleotide sequence data that, when combined with morphological data, will assist in the systematics and phylogenetic reconstruction of these specific sedge groups.

Genomics and evolution of the Clavicipitaceae

A collaboration was developed in 2010 with Dr. Chris Schardl, (http://www.ca.uky.edu/agcollege/plantpathology/schardl/schardl.htm) of the Department of Plant Pathology at the University of Kentucky.  Dr. Schardl’s lab has been examining the biology and evolution of fungal endophytes (Clavicipitaceae, Ascomycota) that infect members of the tribe Pooideae (Poaceae).  These fungal mutualists produce a range of defensive alkaloid compounds, and provide a range of ecological benefits for their infected monocot hosts.  My current efforts involve the genomics and biology of the epibiont Periglandula, a clavicipitaceous fungus that is endemic to select members of the Convolvulaceae (morning glories).  An example of our investigations can be seen through the link below:
