Modeling the Motion of Solid Objects Immersed in Viscoelastic Fluids
… micro-scale objects (often referred to as ``microswimmers'') through biofluids and other viscoelastic media. Additionally, a better understanding of such flows offers the potential to improve the ways in which microrheology measurements are made and interpreted. This thesis aims to develop a …

Propulsion, navigation and control of biological and artificial microswimmers
… involving the locomotion of different types of microswimmers, including both biological microorganisms and artificial colloids. Due to the physical constraints imposed by the inertialess hydrodynamics at these small scales, these swimmers rely on multiple locomotion strategies that are …

Elongated microswimmers: influence of hydrodynamics
… and others. In collective motion, these microswimmers exhibit a diverse behavior such as the formation of swarms, vortices, convection rolls and plumes, and active turbulence. Therby, most microswimmers are elongated, and are otherwise characterized by different swimming mechanisms. …

Artificial Micro-Devices: Armoured Microbubbles and a Magnetically Driven Cilium
… (AMBs) which can self-propel as artificial microswimmers or facilitate microfluidic mixing in a channel when held stationary on a wall. Secondly, we study an artificial cilium, which due to its unique design, when placed in an array, easily produces a metachronal wave for fluid …

Stochastic modeling of Karlotoxin's influence on prey
Karlodinium veneficium is type of dinoflagellate that feeds on planktonic species such as Storeatula major.It is associated with fish kills due to harmful algae blooms by releasing a compound called Karlotoxin. This toxin is known to affect their prey's bio-locomotion by stunning them and slowing …

Biophysics of Helices: Devices, Bacteria and Viruses
… in the microscopic world of artificial microswimmers, bacteria and viruses is that of a helix. The intriguingly different physics at play at the small scale level make it necessary for bacteria to employ swimming strategies different from our everyday experience, such as the rotation of …
