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.

My research interests include free-surface flows and surface tension-related phenomena, such as solid-liquid impacts, bubble dynamics, and hydraulic jumps. I am also interested in problems that involve the coupling of fluid flow and elastic structures, especially those arising in biology and engineering more generally, and bioengineering in particular.

My research interests lie in the distortion of a flexible streamer in a shearing flow. I am currently working on the theory but I am also interested in conducting numerical simulations since I have a Master degree on CFD from Imperial College London and Supaero.

My dissertation research is on capillary dynamics. Specifically, I investigate how drops coalesce, spread, bounce, and splash. I also study how thin films, such as bubbles, rupture - a phenomenon that has implications from the coarsening of foams to oceanic gas-transfer.

My dissertation work encompasses two main research areas. The first involves studying the dynamical behaviour of red blood cells in microfluidics. I Observe different RBC motions such as tank-treading, tumbling, or translating and correlate these motions with functional ATP release in an effort to better understand the physiological significance of such phenomena. My second project involves studying the killing efficacy of biocide agents on biofilms, and the associated kinetics using microfluidic coflow experiments. I am also a project manager and graduate student mentor for the Harvard College chapter of Engineers Without Boarders, which has a manual well drilling project in the Dominican Republic.

My research focuses on elastic stability of soft materials. I'm interested in using elasticity and instabilities such as snap-buckling, crumpling, wrinkling, and folding to generate responsiveness and impact properties such as adhesion, optics, and flow at surfaces or in devices.

I am interested in the study of fluidic phenomena in systems of nanoscale dimensions involving nanopores, nanofluidic channel, and biological structured system. I am also interested in small scale transport in a liquid film and interfaces as occur in many practical and physical models.

I am using model systems (vesicles, supported lipid bilayers) to study protein-membrane interactions in vitro, with a particular focus on the influence of membrane geometry on protein localization. My current work also includes the use of microfluidics to study bacterial adhesion and biofilm formation.

I am interested in processes at liquid/liquid and gas/liquid interfaces. I am focusing on how surfactants (SDS,...) and polymers (PVA, PEO,...) may influence the behavior of these interfaces. This is relevant to understanding how to obtain emulsions, or to improve the stability of foams.

My current research concerns particle transport in microfluidic devices, such as shear-induced diffusion of disk-like colloids or hydrodynamic effects on cell adhesion

My current research is on the numerical and analytical modeling of flow in a micromagnetic-microfluidic blood cleansing device. Prior to this, I have also studied the dynamics of droplet splashing onto solid surfaces, where I was interested in the splashing threshold of impact onto inclined and moving surfaces with respect to various droplet and environment parameters.
