    RESEARCH PROJECT

    I study the deformation and collision of Hele-Shaw drops by coupling feedback control and microfluidics. By manipulating the hydrodynamic force, I steer two dispersed drops within a suspending medium along desired trajectories, ultimately bringing them into coalescence. The practical application of this research lies in the oil-sand industry, particularly in the elimination of unwanted micron and submicron water droplets from bitumen, potentially through coalescence. Additionally, I investigate thin bitumen film drainage using Reflection Interference Contrast Microscopy (RICM).
