4. Graduate Research Assistant, New Mexico Petroleum Recovery Research Center, 05/2002-05/2005
1. Work on US Department of Energy (DOE) research project: "Improving CO2 Efficiency for Recovering Oil in Heterogeneous Reservoirs (DE-FC26-01BC15364)." Experiences including: 
• Solute transport through porous media: Design and conduct core flooding experiments to study surfactants transport through porous media for foam flooding. Describe core compositions and structure by X-ray diffraction, SEM, Thin Section, and AFM to analyze solute transport mechanism through porous media.
• Interaction of liquid/solid: Design and conduct batch experiments to study surfactants sorption onto minerals. Conduct Zeta Potential experiments to understand mechanisms of surfactant adsorption onto minerals. 
• Numerical simulation: Based on laboratory experiment results, model the transport of surfactants through porous media and optimize foam flooding process by using numerical simulator.  
5. Research Engineer/Section Head, Conformance Control, Production Engineering Department, RIPED, PetroChina Company Limited (Petrochina), Beijing, China (05/1995-05/2002) 
1. Worked on projects related to conformance control,chemical EOR and reservoir simulation, funded by CNPC, PetroChina, SINOPEC, CNOOC and oilfields. 
• Development of oilfield chemicals: Synthesized several kinds of gel, such as in-situ weak gel and strong gel, preformed particle gel, and so on, and a temporary plugging agent. These gels can be used in the reservoirs with temperature from 20 to 130 0C and salinity up to 300,000 mg/l and have been successfully applied to control conformance. The temporary plugging agent is characterized by temporarily plugging low permeability zones during gel injection process and automatically dissolving after gel injection.
• Evaluation of oilfield chemicals: Evaluated the influences of reservoir conditions on gel, polymer and W/O emulsions, including effects of temperature, salinity, and reservoir core properties. A series of evaluation methods of gels were developed and were published as a petroleum industrial standard of China.
• Fluid flow in porous media: Designed and conducted core flooding experiments to evaluate the flow behavior and rheology of polymers, gels, emulsions and preformed gel
