Modern nanoelectromechanical devices are used in a broad range of applications, including sensors for mass detection and imaging with atomic resolution, monitoring of biological processes such as DNA hybridization, and mass spectrometry at the molecular scale. These nanoscale devices are frequently operated in a fluid environment - both gas and liquid. The ability to model their behavior is essential for proper device design and characterization.

In an effort towards an understanding of the generation and control of vertebrate locomotion, including the role of the CPG and its interactions with reflexive feedback, muscle mechanics,
and external fluid dynamics, we study a simple vertebrate, the lamprey.
Lamprey body undulations are a result of a wave of neural activation that passes from head to tail, causing a wave of muscle
activation. These active forces are mediated by passive structural forces.

The Euler equations of fluid dynamics is the primary example of a system of hyperbolic conservation laws. Such systems are well-posed in one space dimension under a smallness assumption, but for realistic initial data in multiple dimensions there is a great lack of stability, existence and uniqueness theory. Moreover, certain initial-value problems are indeed unstable with respect to initial data.

In this presentation, the well-established approaches of coupling tsunami generation to seismic seafloor motion and the following trans-oceanic wave propagation will be briefly introduced. The focus of the discussion will be on the complex transformation of the tsunami as it approaches very shallow water, as well as how these possibly large and fast-moving water waves interact with coastal infrastructure. Examples of coastal impact will be discussed and used to frame the theoretical efforts.

The role of mathematics in understanding and simulating fluid dynamics and biochemical processes in the physiological and pathological functioning of the human cardiovascular system is becoming more and more crucial. These phenomena are indeed correlated with the origin of some major cardiovascular pathologies, and influence the efficacy of the treatments to heal the arteries from their diseases.

Mathematical models allow the description of the complex fluid-structure interaction which govern the

The dynamics of droplet breakup in Newtonian fluids are
described by the Navier-Stokes equation. Previous experiments
have shown that in many cases
the breakup dynamics follow a self-similar behavior where
successive drop profiles can be scaled onto one another. In
visco-elastic systems however,
the Navier-Stokes equation is not sufficient to describe
breakup. In this talk we will describe droplet breakup in a
visco-elastic surfactant system
which forms micellar, lamellar, and reverse-micellar phases at
