Estelle Clerc visited us from the Stocker Lab (ETH, Switzerland) to conduct in situ chemotaxis assays at the UGA Marine Institute on Sapelo Island. In collaboration with Andrew Fu and Jeremy Schreier, Estelle collected data for her Ph.D. research on the key bacterial chemotaxis to marine phytoplankton exudates in marine ecosystems, including the identity of key metabolites and bacterial taxa involved.
