Who said that turbulence always mixes? Check out this paper showing that motility in turbulence can lead to un-mixing. Life looks pretty turbulen 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!
Starting this week, we’ll have Rebecca Schilling taking good care of our lab: We’re thrilled by this new addition to the group!
Postdoc Gabriel Juarez wins first prize (and an iPad!) in MIT’s postdoc poster competition with an elegant, minimalistic poster on how marine bacteria find oil droplets. Gabe’s research aims to understand the biophysics of oil degradation.
Postdoc Filippo Menolascina will give a talk next Wednesday April, 17th on “What High School science should have been” in an event organized by the MIT Museum for the Cambridge Science Festival 2013.
Kick off time: 6pm. More info here. Go Filippo!
Postdoc Melissa Garren wins the award for the best talk by a junior scientist at the second edition of the symposium on “Microscale Interactions in Aquatic Microenvironments”, held at the École de Physique des Houches, France. Melissa talked about the role of motility and chemotaxis in a coral pathogen.Congratulations Melissa!
Gastón is a physicist from Argentina and will be working in collaboration with Mimi Koehl and Nicole King, from the University of California Berkeley, on the role of motility and nutrient uptake in the evolution of multicellularity in choanoflagellats. Bienvenido Gastón!
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.
Roman answers NSF’s Jacqueline Conciatore’s questions on doing science, being inspired, and what to salvage if your lab goes up in flames.
Mack Durham delivers the Andreas Acrivos Dissertation Award lecture at the Division of Fluid Dynamics meeting in San Diego. This award recognizes “exceptional young scientists who have performed original doctoral thesis work of outstanding scientific quality and achievement in the area of fluid dynamics”. Mack’s thesis focused on “Phytoplankton in Flow” and he is now a lecturer at Oxford.
Seven from the Stocker group attends the American Physical Society Division of Fluid Dynamics meeting in San Diego, to present our work on bacterial motility and biophysical interactions among marine microbes.
“Oceans at MIT” features a story on the lab’s focus on the hidden life of marine microbes.
Roman’s review paper on microscale gradients appears in Science. The review, titled “Marine microbes see a sea of gradients”, highlights the importance of microscale processes in the ocean.
John Taylor and Roman Stocker’s paper on the effects of turbulence on marine bacteria appears in Science. The paper, titled “Trade-offs of chemotactic foraging in turbulent water”, describes how turbulence affects the competition for nutrients among marine bacteria. John is a former postdoc and now a lecturer at Cambridge University.
Jeff Guasto secures a tenure-track faculty position in Mechanical Engineering at Taft University, starting Sept 2013. Most deserved, Jeff: we will miss you, but are very excited for you!
Steve Smriga is awarded a 2-year Postdoctoral Research Fellowship from the Division of Ocean Sciences at NSF. We look forward to some exciting work together, Steve!
Ph.D. student Bennett Lambert joins the lab. Ben is a Mechanical Engineer from Alaska and will be working on a collaboration with Rob Olson and Heidi Sosik at the Woods Hole Oceanographic Institution to design a microfluidic sorter and integrate it with the Imaging FlowCytobot, an automated submersible flow cytometer. Welcome, Ben!
Prof. Yvan Lagadeuc from the University of Rennes, France, joins the lab for a one-year sabbatical, to work on luxury uptake in phytoplankton by integrating a new microfluidic approach and NanoSIMS imaging. Bienvenue Yvan!
Postdoc Melissa Garren wins the J.W. Costerton Award at ISME-14 in Copenhagen for “research that advances a new theory in microbial ecology that also has interdisciplinary significance”. Melissa’s poster was titled “The need for speed: A marine pathogen uses rapid chemotaxis and chemokinesis to target its host.” Well done, Melissa!
Postdoc Yutaka Yawata wins the Brock Postdoctoral Research Award at ISME-14 in Copenhagen for his talk “Mapping
genotypic diversity onto niche adaptation”. Omedetou, Yutaka!
Our new admin Ruth joins the group: welcome Ruth and we all look forward to working with you!
Postdoc Orr Shapiro wins a poster award at the Gordon Research Conference on Marine Microbes at Il Ciocco, Tuscany, for his poster “Reef on a chip: Studying coral-pathogen interactions at the microscale”. Mazel tov, Orr!
Roman gives an invited talk at the Gordon Research Conference on Marine Microbes on “Bacterial Behavior in a sea of gradients.”
Our admin Roberta leaves us … grazie Roberta for all your help and buona fortuna for your new life in Italy!
It’s been an exciting journey!!
Gabriel Juarez joins the lab as a postdoc. Gabe is from Texas and studied physics. He will be working on bacteria-oil interactions.
The Stocker lab gets a new home! We have moved and here is our new lab. We’re excited about this new space!
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!
