Graduate Assistantship in Aquatic Science – Ecosystem Impacts of Amphipod Viral Infection

infection of marine zooplankton and benthic metazoa is an emerging frontier in
aquatic microbiology and biogeochemistry. Recently described circular ssDNA
viruses associated with marine copepods, freshwater cladocerans, and aquatic
amphipods extend the known host range of these viruses, and raise interesting
questions about their biogeochemical and ecological effects on aquatic food
webs. The extent to which zooplankton viruses affect rates of detritivory and
herbivory, and the subsequent impacts on ecosystem biogeochemistry remain

laboratories of Ian Hewson (Microbiology:

at Cornell University seek an outstanding graduate student researcher (starting
June 2014) to work on an NSF-funded biological oceanography project to examine
the impacts of circular ssDNA viruses on benthic amphipod ecology in the
Laurentian Great Lakes and Coastal California. This interdisciplinary project
will train the student in tools of molecular microbiology/virology and
genomics, ecology, oceanography, disease epidemiology, and biological statistics.  The student will be based at Cornell’s
Ithaca, NY campus, but will be expected to regularly travel to the Cornell
Biological Field Station at Shackleton Point (CBFS: and field
sites on the Great Lakes and California to conduct in situ study. The student will work in a dynamic team comprising
the PIs, postdoctoral fellows, and other graduate student and undergraduate
student researchers, across the disciplines of Microbiology, Ecology, and
Natural Resource Science.  The student
will also participate in outreach activities in collaboration with a local high
