Who said that turbulence always mixes? Check out this paper showing that motility in turbulence can lead to un-mixing. Life looks pretty turbulent out there in the oceans! Congratulations to Mack Durham (former PhD student and now lecturer in Oxford) and Mike Barry, and to our collaborators in France and Italy.
Kwangmin and Jeff’s paper in Nature Physics shows that marine bacteria reorient by causing the buckling of their flagellum. Pretty resourceful bugs out there in the Ocean!

A comprehensive review of bacterial chemotaxis in the ocean by Roman Stocker and Justin Seymour appears in Microbiology and Molecular Biology Reviews. Justin is a former postdoc in the group and now a Senior Research Fellow at the University of Technology Sydney. An image of bacteria clustering around a diatom, by group members Steve Smriga, Kwangmin Son, Vicente Fernandez and Roman Stocker, appears on the cover.
Roman Stocker is selected as a Marine Microbiology Initiative Investigator by the Moore Foundation. This award will considerably enhance the lab’s abilities to investigate microbial processes in the Ocean over the next 5 years. Read full announcement.

Our paper on swimming in stratified fluids appears in PNAS. Roman collaborated with the group of Arezoo Ardekani, a former postdoc and now faculty at Notre Dame University.
Our paper on bacterial rheotaxis appears in PNAS. We show that hydrodynamic shear produced an unexpected torque on bacteria, making them drift across the flow due to the chirality of their flagella. This work was led by former Ph.D. student Marcos, now a faculty at NTU in Singapore, in collaboration with Henry Fu and Thomas Powers.
Roman co-organizes the department’s research speed-dating event, the second episode of the Department of Civil and Environmental Engineering lightning-talks aimed at fostering research cross-fertilization. This year with jazz band!
