Quite unexpected collective behavior is often observed in complex open systems when many similar nonequilibrium units couple with one another, resulting in synchronization, pattern formation, emergence, broken symmetries, and phase transitions. My research is focused on experimental studies of instances of such collective behavior and the problems that I am interested in stem mainly from the domains of condensed matter physics, nonlinear dynamics, biology and fluid dynamics.

I am specialized in a threedimensional velocimetry for microfluidics flow. I hold special interests in understanding hydrodynamics instabilities (thin film instability) and microfluidics applications (electrokinetic flow). I am very open to cooperate with other topics, e.g. biology (thinfilm flow in vivo or the flow field surrounding a living organism). However, to study fundamental problems in fluid dynamics is still at the core of my research.

My research focuses on the energy issues that are relevant to human. In large scale, I am interested in energy management technologies that are environmentally benign, such as refrigerantfree cooling, waste heat recovery, and clean energy harvesting technologies.

My research is located at the interface between hydrodynamics with flow of complex fluids such as foams or polymer solutions, physicalchemistry of colloidal suspensions as well as continuum mechanics based on consolidating materials. These different topics address fundamental problems in Soft Condensed Matter Physics while maintaining a connection with applications.

I am interested in migration and adhesion of various kinds of biological cells on soft substrates. My primary tool for these projects is traction force microscopy. Besides studying biologyrelated subjects, I also enjoy to think about fluid mechanical themes, such as artificial microswimmers and phoretic mechanisms. Finally, I study properties of networks with local magnetic breaking of timereversal symmetry.

My research focuses on the fundamental understanding, control and design capabilities of multiphase flow dynamics in porous media. I combine theory, experiment and numerical simulation to study the basic flow patterns, such as viscous fingering, crack propagation and gravity currents; and their application to the control and design problems on energy, health and art topics, such as oil and gas recovery, CO2 storage and Chinese painting. I'm also interested in energy system and policy research from the theoretical modeling point of view.

I study flow phenomena in which behaviour at an interface and interactions between interfaces play an essential role. I am interested in droplet coalescence, flows driven by variations in surface tension (Marangoni flows), and electrokinetic phenomena in multiphase flow. I often use high performance computing, including recent technologies such as GPUs, to investigate these systems.

Currently I am working on two problems: 1. Finding the Smoluchowski analog for chemical reactions taking place in membranes (including hydrodynamic interactions). 2. Rotation and translation coupling for a particle in an environment of varying viscosity. I'm assuming there will be other cool problems in the future.

No bacterium is an island. In their natural environment, bacteria survive in a structured community called biofilm. By secreting polysaccharides and proteins, bacteria stick themselves together to fight against predators and antibiotics. In order to combat bacterial infections we need to understand how bacteria form such biofilms, yet our knowledge about the formation process of biofilm is limited. Combining stateofart optics, microfluidic techniques, and genetic tools, I am starting to unveil the underlying principle of biofilms, using the notorious pathogen Vibrio cholerae as a model organism.

My research focuses on fabrication of nanoemulsions using interface technique. In a system with a thin oil layer on top of water, the bursting process of gas bubbles at the interface of water and air will disperse nanoemulsions of oil in the water phase. I am currently looking at the influence of different parameters on the size of nanoemulsions, such as the bubble size, viscosity and surfactants, to get more insight into the mechanism for a better control. I am also interested in nearsurface flow characteristics of slippery liquidinfused porous surface and transport phenomena in porous soft matter.

I am interested in a broad range of biophysics problems. My work is mainly on the dynamics of collective chemosensing in cells; most recently I have been studying how this process is coupled to the mechanical sensing of the tissue rigidity. I also studied problems involving red blood cell aggregates called rouleaux, i.e. how they form and breakup during flow, and also modulation of aggregation using longchain molecules.

I am interested in a range of problems that involve flow over deformable boundaries. In one of my projects, I am interested in the fluidstructure interactions between a fluid environment and a highly flexible fiber, such as the flow around kelp, grass, whiskers, and other biological structures. More recently, I have been exploring the dynamic response of a thin film on a body subjected to external flows and its potential ability to reduce drag.

My research focuses on the printing of nanomaterial based functional devices. Currently, I am studying the fluid dynamics of colloidal nanoparticles deposition on a variety of substrates. I am also exploring alternative printing strategies that could overcome the geometrical limitation as well as material integration challenges of conventional microfabrication techniques. Such approaches may complement existing fabrication technologies and ultimately enable the creation of novel biomedical or electronic devices.

I'm interested in the physical understanding of fluid motion involving interaction with elastic boundaries. The coupled fluidelastic solid problems could be widely found both in nature, e.g. magma transportation and membranefluid interactions, and in industry. e.g. hydraulic fracturing. We developed an original experiment model to study the cracking process of fluiddriven cracks in a elastic reservoir, as well as the viscous backflow driven by reservoir elasticity. My goal is to use elegant experiment models to capture the significant physics involved in the real systems.
