Field Research

We routinely conduct field research projects capturing live forams for culture experiments or capturing recently alive forams to establish the geochemistry of modern specimens. We've recently expanded this work to study the effects of marine heat waves on foraminifera ecology (their assemblages) and are conducting genotyping and metabarcoding analyses to establish symbiont/microbial associations. Follow the links below to learn more about a few of our past and present projects:

Field work on Green Island, Taiwan:
In May 2019, we travelled to Green Island, Taiwan to diversify the species we study in the culture setting beyond those we typically find off the coast of Catalina Island (where most of my field work has taken place). Learn more about the Taiwan projects here.

Field work on the Oregon Coast:

Since arriving at OSU in 2016, most of our field work has taken place on short research cruises, mostly through 'Ships of Opportunity' - we have been lucky to tag along on research cruises coordinated by many of my colleagues and collaborators. We were recently funded to deploy 2 sediment traps off the coast of Oregon, and will service the traps every 6 months for the next several years. Members of my lab have sailed on the R/V Sikuliak, the R/V Oceanus, the Elakha, and the NOAA Bell M. Shimada. Learn more about our Coastal Oregon projects here.

Field work on Catalina Island
My first field season took place on Catalina Island at the Wrigley Institute of Marine Science in 2011. We had additional field seasons in 2013 through 2016. We mostly conducted experiments on deeper dwelling forams, but several small projects included spinose species. I can't wait to get back there for future field work.
