I am interested in the population and community ecology of marine algae and seagrasses. My students and I are often involved in projects relevant to the management of Humboldt Bay. Active projects include the updating of the seaweed flora for northern California, examining the eelgrass and invertebrate response to the grazing of eelgrass by black brant geese, the examination of bottom up limiting factors to eelgrass, and the description of the phytoplankton community in the bay. I am also involved in CSU collaborative effort to set up an integrated ocean observation platform to monitor near shore marine water quality.
