Research Summary
We actively study problems involving fluid dynamics and transport phenomena in micro/nano confined spaces. The problems are inspired by microfluidic systems for biochemical analysis and cellular engineering. Especially, we are interested in electrokinetic phenomena, e.g., electrophoresis, electroosmotic flow, and electrowetting, of complex fluids including cells and biomacromolecules. We recently developed a microfluidic system that enables the high-throughput sequencing of cytoplasmic and nuclear RNA with the physical fractionation of the RNA species via electrical lysis and isotachophoresis. We leverage our method to uncover the regulation of gene expression involving RNA localization and transport in single cells.
