Student: Niti Nararidh
Advisor: Dr. Hoa Nguyen
Abstract: Choanoflagellates are unicellular organisms whose intriguing morphology includes a set of collars/microvilli emanating from the cell body, surrounding the beating flagellum. We investigate the role of the microvilli in the feeding and swimming behavior of the organism using a three-dimensional model based on the method of regularized Stokeslets. This model allows us to examine the velocity generated around the feeding organism tethered in place, as well as to predict the paths of free flowing particles. In particular, we can depict the effective capture of nutritional particles and bacteria in the fluid and the hydrodynamic cooperation between the cell, flagellum, and microvilli of the organism.
