Collective motion of chemotactic bacteria as E. Coli relies, at the individual level, on a continuous reorientation by runs and tumbles. It has been established that the length of run is decided by a stiff response to temporal sensing of chemical cues along the pathway. We analyze consequences on self-organized pattern formation resulting from modulation of tumbling frequency with stiff response. Thanks to both analytical arguments and numerical simulations, we show that the stationary…

The flux limited Keller–Segel system; properties and derivation from kinetic equations
The flux limited Keller-Segel (FLKS) system is a macroscopic model describing bacteria motion by chemotaxis which takes into account saturation of the velocity. The hyper-bolic form and some special

The flux-limited Keller–Segel–Navier–Stokes system is described, which aims to provide real-time information about how the input and output of the system is changed over time over a sustained period of time.


Dynamics of formation of symmetrical patterns by chemotactic bacteria
The pattern geometries of Escherichia coli aggregate to form stable patterns of remarkable regularity when grown from a single point on certain substrates, and vary in a systematic way, depending on how long an aggregate remains active.
Directional persistence of chemotactic bacteria in a traveling concentration wave
By studying individual trajectories within the propagating wave, it is shown that, not only the mean run length is longer in the direction of propagation, but also that the directional persistence is larger compared to the opposite direction.
Derivation of the bacterial run-and-tumble kinetic equation from a model with biochemical pathway
This program shows how the first class of equations can be derived from the second class with molecular content after appropriate rescaling, and how Randomness of receptor methylation events can be included and used to compute the tumbling frequency in presence of such a noise.
Traveling Pulses for a Two-Species Chemotaxis Model
This work extends the approach to study the behavior of the interaction between two populations of E. Coli using a macroscopic model of partial differential equations and shows that synchronization depends on the fraction of the fast population.

Mathematical Description of Bacterial Traveling Pulses
This model is derived from an accurate kinetic description of the mesoscopic run-and-tumble process performed by bacteria and is intended as a predictive tool for the investigation of bacterial collective motion.
Kinetic models for chemotaxis: Hydrodynamic limits and spatio-temporal mechanisms
We study kinetic models for chemotaxis, incorporating the ability of cells to assess temporal changes of the chemoattractant concentration as well as its spatial variations. For prescribed smooth
Frequency-dependent Escherichia coli chemotaxis behavior.
A new continuum model is proposed to describe the population level behavior of E. coli chemotaxis based on the underlying pathway dynamics with the inclusion of a finite adaptation time and an attractant consumption rate that successfully explains the microfluidic experiments at different stimulus frequencies.
From Individual to Collective Behavior in Bacterial Chemotaxis
This work derives and analyzes a macroscopic system of hyperbolic differential equations describing the motion of individuals such as bacteria from a microscopic model of the behavior of individual cells using moment closure techniques in one space dimension.
