Research Interests
I
am interested in population genomics and ecology, and their broader
applications to conservation. For my dissertation, I plan to study a
population of golden monkeys (Cercopithecus kandti) in Gishwati
National Forest Reserve in Rwanda. Golden monkeys are an endangered
species of guenon that occur in only three locations in central Africa.
The Gishwati population resides in an isolated forest fragment and
requires further research to optimize conservation efforts. Toward this
goal, I will use fecal DNA to determine the level of inbreeding in the
population and behavioral observations to estimate the population size
and structure, and to describe the general behavior and feeding ecology
of the Gishwati population. Unlike the other two golden monkey
populations, which live in forests dominated by bamboo, the Gishwati
golden monkeys live in largely secondary growth forest more similar to
habitats of other forest guenons. I also hope to use fecal DNA to
identify whether hybridization occurred between the golden monkeys in
Gishwati and the closely related blue monkeys (Cercopithecus mitis) of
Nyungwe Forest Reserve to the south, which was once connected to
Gishwati forest.
