Luke
McGowan
Luke officially joined the Striedter lab in the
summer of 2008. Luke's principal research interests span
evolutionary neuroscience, evo-devo, animal behavior, and
the history and philosophy of biology. His first project in
the Striedter lab has been to develop in situ hybridization
methods for examining gene expression at early stages of
brain development, right around the stages when the brain's
major divisions are established. Although some of the
needed in situ hybridization probes are available for
mammals and chickens, Luke has had to develop new probes to
look at other species, such as parakeets and quail. Luke
has also begun to work out methods for manipulating brain
region size experimentally (e.g. by injecting cell division
inhibitors into the brain of young chicken embryos). In the
long run, he wants to use these methods to test hypotheses
about the developmental mechanisms through which evolution
changes neuronal circuitry. The picture below shows one of
Luke's embryos, hybridized with probes for Pax6 and Gbx2 so
that the midbrain remains unlabeled. When Luke is not
working on neuroscience, he spends his time in Los Angeles
gardening, hiking, reading literature and exploring the
arts.
