Mehdi and collaborators have published an article on the interesting ways in which Helicobacter suis, which has two tufts of flagella, one at each pole, can swim. The tufts form flagellar bundles which can be either extended from the body or wrapped around the body, leading to combinations of both wrapped, both extended, and one […]

As part of a group of investigators, we have received an award to develop mathematical models of the gastric mucus layer and use them to understand bacterial infection in the stomach as well as gastric organoids, spherical reconstructions of gastric tissue that can be used to study gastric function and disease. Besides our group, the […]

Mehdi has published a paper investigating how viscous constraints influence the ability of swimmers using different swimming strategies to closely approach other suspended particles, for example to feed, mate, or find new habitats.

We received a second NSF award to study how the physical constraints posed by viscous hydrodynamics influences the form and swimming strategies of microorganisms. This award is in collaboration with Rob Stoll, also in our department at the University of Utah. [CBET-1805847, Viscous Constraints on Zooplankton Approach and Interaction]

In collaboration with MinJun Kim at Southern Methodist University, we have received a new NSF award to study how contact interactions between microorganisms and the microstructure of complex media affect swimming. We will combine experiments using artificial bacteria and synthetic mucus with theory and modeling. [CMMI-1760642, Collaborative Research: Controlled Investigation of Micro- and Nanoscale […]

Mehdi has published an article describing how the dynamical buckling of bacterial hook and flagella combine to trigger flick motility in monotrichous bacteria. His model is the first to quantitatively predicts the onset of flicks seen in experiments. [M. Jabbarzadeh and H. C. Fu, “Dynamic instability in the hook/flagellum system that triggers bacterial flicks,” Phys. […]

JD and Mehdi, in collaboration with Jamel Ali and MinJun Kim’s group at Southern Methodist University, have published a new paper describing artificial bacteria-inspired nanorobots. The nanorobots consist of a magnetic nanobead to which is attached one or two reconstituted bacterial flagella. The swimming speeds of the robots can be altered by triggering polymorphic transformations […]
