Research Interests:
My current research interests are focused on the reconstruction
of phylogeny of the genus Chlamydomonas and its allies (including Carteria, Haematococcus, Chloromonas, and Chlorococcum).
In addition, I am studying the enigmatic group of green algae known as the Sphaeropleaceae. As a consequence of
my diverse green algal interests, I remain interested in reconstructing the phylogeny of the "big picture"
for the Chlorophyceae, in particular, and the Chlorophyta, in general. Analyses of nuclear-encoded ribosomal RNA
gene sequences (18S, 26S and ITS) and chloroplast-encoded rbcL are being used to infer phylogenetic relationships.
Lastly, I served as PI and member of the Executive Committee of Deep Green,
a USDA/NSF/DOE-funded project (1994-2000) involving the coordination of research effort in green plant phylogeny
(i.e., the study of phylogenetic relationships among the major green algal and embryophyte lineages).
I am currently working to develop both funding and outreach for deepestgreen,
a coordinated research effort for the phylogenetic investigation of the Chlorophyta. The Chlorophyta is one of
two branches of the Viridiplantae (Green Plant) lineage. The Chlorophyta includes extant members that possess a
fossil record that extends back into the Precambrian.
