Research Interests
I am interested in looking at conventional and non-conventional indicators of trace metal contamination of the environment. The study area for my dissertation is an island in the Philippines that is impacted by a mine tailings spill. Dispersion of mine waste in the ocean is traced through the marine sediment profile as well as in the annual growth bands of massive corals. The effects of acid mine drainage on the Boac River is also investigated through annual sediment and river water sampling. This is compared with the distribution and metal bioaccumulation of select benthic organisms and in the properties of metal sulfate precipitates in the river. This study is closely patterned after the group’s various research projects in San Francisco Bay and in the Clark Fork River.
