I obtained my B.S. degree from the Department of Thermal Engineering of Tsinghua University (Beijing). Then I headed my postgraduate studies in University of Science and Technology of China (Hefei) and received my M.S. degree in Thermophysics under the supervision of Professor Xinshi Ge. Before I pursued my Ph.D. degree in Mechanical Engineering from  University of Alberta (Edmonton), I had worked in Shanghai Institute of Electric Power for six years. During my five-year Ph.D. program supervised by Dr. Dongqing Li (now with University of Waterloo) and Dr. Jacob H. Masliyah, I also had been with Syncrude Canada Ltd. - Edmonton Research Centre under the NSERC-Oil Sands Industry Chair Program for three years. In 1999, I joined the Nanyang Technological University as an Assistant Professor.

        Novel Electrokinetic Power Generation via Forward Osmosis

We have proposed a new power generation method for harvesting renewable energy from salinity gradient that is available from seawater, brackish water and concentrated brine discharged from desalination plants. The principle of the proposed method encompasses forward osmosis (FO) and electrokinetic (FK) phenomena. Our preliminary results show that the FO-EK technique can produce electrical voltages in the same order of magnitude as those produced by one typical fuel cell unit. The projected power density based on our experimental results is comparable to those generated by pressure-retarded osmosis (PRO) and reverse electrodialysis (RED) technologies. We are working on modeling and scalability development.

        Thermophoresis of Micro- and Nano-Particles

The main objective of the present project is to carry out both theoretical and experimental studies to directly address several fundamental issues related to thermophoresis. Experimentally, we propose a microfluidic technique as a new experimental tool to directly visualize and characterize the dynamic behavior of both micro and nano-sized particles under various physicochemical conditions. Meanwhile, new theoretical modeling and analysis of theremophoresis by using both analytical and numerical approaches are carried out.

        Electrokinetic Flow of Non-Newtonian Fluids

This topic is of high relevance for electrokinetically-driven microfluidic and nanofluidic systems which are routinely used to process and analyze non-Newtonian fluids, such as biofluids, polymeric solutions and colloidal suspensions. Our current research focuses on fundamental understanding and characterization of the electrokinetic flow of non-Newtonian fluids.

        Microfluidic Separation of Live and Dead Cells in Continuous Flow

We are developing polymer micro flow cytometer with applications in environmental monitoring. Flow cytometry is a technique for counting, examining and sorting biological cells and particles suspended in a liquid stream. Our proposed micro flow cytometry will highlight the following features: (i) alignment of cells via hydrodynamic focusing, (ii) separation of live and dead cells via dielectrophoresis, and (iii) on-chip counting.

        Induced-Charge Electrokinetic (ICEK) Flow and its Applications

Induced-charge electrokinetics deals with a new group of non-linear electrokinetic phenomena. The project aims at theoretical advancement of nonlinear ICEK flows and exploration of their applications in micro/nano fluidics. In particular, we are working on derivation of generalized electric boundary conditions, dynamic characteristics of the charging of electric double layers and the associated induced flows around polarizable dielectrics, implementation of ICEK phenomena to nanofluidics, and the use of ICEK flow for particle manipulations.

        Characterization of Thermoplasmonic Heat Transfer in Liquids

This project is to fundamentally study thermoplasmonics with emphasis on ensemble effects. Thermoplasmonics refers to a new phenomenon involving the resistive heat-loss in nano-sized metallic particles under light illumination due to their enhanced absorption capabilities. We are carrying out both experimental investigation and theoretical analysis to characterize thermoplasmonic heat transfer with exploring applications in energy utilization and storage.
