Dr. Lisa Fauci, Tulane University – Insights from biofluidmechanics: A tale of two tails

February 1, 2023 @ 4:00 pm - 5:00 pm

Mode: In-Person

Title: Insights from biofluidmechanics: A tale of two tails


I will present recent work on two very different systems at very different scales, both involving fluid flow driven by undulatory motion. The first is a class of microorganisms, choanoflagellates,

that are important predators on bacteria in aquatic ecosystems.  A unicellular choanoflagellate waves a flagellum to swim and to create a water current transporting bacterial prey to a food-capturing collar of microvilli.  While load-carrying effects on high Reynolds number flight have been studied, the fluid dynamics of load-carrying by microorganisms has received less attention.  I will discuss coordinated laboratory experiments and simulations that investigate the swimming and feeding performance of choanoflagellates carrying bacterial prey.  The second model organism I will discuss is the lamprey.  Using a closed-loop model that couples neural signaling, muscle mechanics, fluid dynamics and sensory feedback, we examine the hypothesis that amplified proprioceptive feedback could restore effective locomotion in lampreys with spinal injuries.
