Research Interests

Transport Phenomena; Fluid mechanics and statistical physics, stochastic processes to investigate the transport of suspended particles in complex systems. Our objective is to develop a fundamental understanding of transport at small scales by combining theory and numerical simulations with experiments. Our objective is also to use this basic understanding to create micro and nanofluidic devices with improved capabilities over conventional systems, in fields such as separation sciences.
