Fluid motions dominated by viscosity, so-called low-Reynolds-number flows, have many applications, including the lubricating motions important to the operation of mechanical equipment (and joints), coating flows important to a myriad of industrial applications, and flows and transport processes in microdevices (MEMS) that are finding many new applications owing to their use for handling small quantities of (possibly expensive) liquids and for manipulating polymers. The flow of many suspensions are also often dominated by viscous effects as are the way in which fluid moves in foams and dense colloidal suspensions. Professor Stone and his research group actively work on projects in each of these areas of fluid dynamics. Several of the projects combine theory and experiment in order to more fully explore the limits of both.

Another common theme of viscous flow theory being pursued by Professor Stone and his collaborators is the dynamics of fluid-fluid interfaces. This research includes analytical and numerical studies (often using integral equation methods) of (1) the stretching and breakup of fluid threads and (2) the effect of electric fields on drops and other fluid-fluid interfaces. Because a complete understanding of some viscously dominated flows (such as lift forces) may require incorporating the influence of inertia, Professor Stone also uses asymptotic methods to study flows at small, but finite, Reynolds numbers.

Many biologically inspired problems occur in the viscously dominated flow limit. Professor Stone has studied several problems concerning the flow of lipid monolayers and bilayers, and has investigated the motions of particles suspended in such interfacial layers. This research area is actively pursued by researchers at the interface of chemistry, physics and engineering.

I am currently studying the rheology of hydrogel microfibers, especially its gelation behavior through mechanical interlocking. Such gelation method could become a new way for creating the scaffold for 3D cell culture without the use of cytotoxic chemicals. In the years as a PhD student, I used both theory and experiments to study nanoscale Ohmic heating, electrospray water-in-oil droplet generation and electrospray cell encapsulation for biomedical applications.

Coming from a background in physics and pure mathematics, my research interests lie at the junction of fluid dynamics and material science as a theoretical approach to study the physics of soft condensed matter systems. Among other numerical or theoretical methods, I am most curious about applying symmetry and topological arguments to understand these systems. On the fluids side, I currently work on numerical simulations of multiphase separating systems coupled with hydrodynamic flow, and theoretical models for gel-fluid interaction problems. Beyond that, I have also been working towards understanding the effects of symmetry-breaking and non-trivial topologies on wave propagation in elastic metamaterials.

Fluids come into contact with a wide variety of materials. I am currently interested in exploring the interplay between fluid dynamics and soft materials. Specifically, I am interested in problems where externally driven fluids come into contact with soft/deformable objects, allowing the fluid flow to change the domain shape dynamically. Such non-trivial interactions and dynamic domain-boundary problems are ubiquitous in biophysical and geophysical contexts. I use theoretical frameworks and computational simulations to understand the non-trivial emerging dynamics and beautiful emerging patterns.
