My primary research interest focuses on understanding how
environmental and biological factors influence the fate of
metal bioavailability in aquatic insects. Different groups
of insects are used as bioindicators of metal contamination
in a mine impacted stream, including caddisflies, stoneflies,
and craneflies. Currently, I am working towards quantifying
the proportion of metal uptake in caddisflies through both
the dissolved and dietary phase.
Conducting long-term field studies is also
an important component to my research. Ongoing work in the
Clark Fork Basin, Montana and San Francisco Bay, California,
has been used to identify bioaccumulation patterns associated
with localized inputs of pollutant loads and trends related
to natural variability.
