Phytoplankton floating in the ocean, sperm moving through the reproductive tract, and fish swimming in the sea all rely on an intricate interplay of forces. These are examples of how flexible structures interact with a surrounding fluid – a common theme in biological fluid dynamics. This lecture will explore how mathematical models and computational simulations are being used to study some intriguing biological systems.

Abstract: Various rich dynamics of vesicles under linear and nonlinear
flows will be discussed. We present analytical and numerical
results on tank-treading motion, tumbling and
vacillating-breathing (aka swinging, trembling). We then
discuss the notion of transverse migration due to a wall and to
a nonlinear flow. We show theoretical and exeprimental results
on the law of transverse migration in a microfluidic device.

The goal of this lecture is to inform the audience of the types of challenges that arise, and open problems that remain, in a specific class of biological fluids: mucus. Mucus is prevalent in biology and its rheology is fundamental for: locomotion (e.g., of snails); flow transport (e.g., of mucosal layers in mammalian lungs); and controlling diffusive transport of invasive particles (e.g., in the nasal cavity, lung, and reproductive organs). Mucus varies dramatically across species, across populations, across organs, and in a single organ across disease states.

Biologically active fluids, such as bacterial suspensions or
cytoskeletal extracts with molecular motors and ATP, are a source of
intriguing problems in the physics of complex fluids. They are composed
of particles that with internal machinery that take up energy from their
surroundings and actively move the surrounding medium. My talk will
review recent results on thin fluid films and drops of active fluids,
and possibly the dynamics of a single stiff filament in an active film.
