Walton Green is a Connecticut Yankee who has assiduously avoided
acquiring marketable skills in 12 years spent collecting degrees from
universities on two continents. His recently completed doctoral
dissertation presented to the Department of Geology & Geophysics of
the Sheffield Scientific School proposes a new palaeoecological method
for analyzing forests based on architectural attributes of the leaves
they produce. In addition to plant palaeoecology, leaf architecture,
and the graphical display of quantitative information, his research
deals with evolutionary theory, Mesopotamian archaeobotany, and R.
Don’t ask him what R is unless you have several free hours. His
avocational interests include amateur drama, squash racquets,
tree-climbing; sailing, old novels, and doggerel rhyming.

Smith, R.H. Ree and M.J. Donoghue. Incorporating fossil data in
biogeographic inference: A likelihood approach. Evolution (in press).
While
conducting fieldwork as an undergraduate in Costa Rica, Brian became
irrevocably fascinated by the patterns and generative processes of
biodiversity. Episodes of explosive speciation, adaptive radiation,
species selection, key innovation, and mass extinction are a few
examples of biological phenomena involving differential rates of
diversification. Brian’s doctoral research has focused on developing
and implementing phylogenetic methods to explore these evolutionary
processes, and is applying these new methods to explore a number of
specific empirical problems (including the geographic context of
lineage diversification and the role of biogeographic history on rates
of cladogenesis). Brian is completing his doctoral research under
Michael Donoghue at Yale and will soon commence postdoctoral research
with John Huelsenbeck at the University of California at Berkeley.

Quinn River Crossing, northwestern Nevada, and implications for the
cause of the Early Triassic chert gap on the western Pangean margin. Geological Society of America Bulletin 118(5–6): 733–746. doi: 10.1130/B25803.1
My research focuses on major events in the history of animal life, such
as the Cambrian radiation and mass extinctions. My masters research
involved a stratigraphic and sediment geochemistry study of two
potential Permian–Triassic boundary sections in the western United
States. My doctoral thesis will look at the various factors involved in
the polyphyletic radiation of biomineralizing organisms near the base
of the Cambrian. Originally from Seattle, I did my undergraduate and
masters studies at Stanford University, and worked at the South
Australian Museum and Dartmouth College before coming to Yale.
