Research interests

1# Single cell biology Single cell is the fundamental building brick of life. However, the majority understanding of cellular biology and genetics has been collected through the bulk experiment from large population of cells. Traditional method for single cell analysis have been limited by the cost and throughput required to pick up wanted individual cells from large number of cells and the difficulties coupled with analyzing small amounts of starting material. To address this fundamental biological issue with increasing precision, we should study the questions through the integration of various technologies with the capability of quantification.

2# Microfluidic chip Microfluidic chips represent a new opportunity for performing chemical or biological experiments at nanoliter scale with a unprecedented spatial and temporal control. This approach can be used to plumb single cell issues with several promising advantages such as scale compatibility of mammalian cells, friendly coupling of imaging process, flexibility of manipulating cells and automation. Therefore, my interests mainly focus on the single cell biological analysis in microfluidic device which can be coupled with other methods easily, such as chromatography, electrochemical detection, nano-materials based probing and even with single molecule experiment. Understanding the complex biological systems at single cell level is therefore one of the most pivotal mission in life science research.

3# RNA-Seq The second technology I have worked for recent years is single cell mRNA transcriptome sequencing. This application allow us interpreting the dynamic gene transcription networks during some specific biological events such as stem cell differentiation, cancer metastasis or programmed cell death. We developed a microfluidic approach to prepare cDNA from single cells for high-throughput transcriptome sequencing. The microfluidic platform facilitates single-cell manipulation, minimizes contamination, and furthermore, provides improved detection sensitivity and measurement precision, which is necessary for differentiating biological variability from technical noise. We recently published this work on PNAS (2014, 111, 7048-7053). This work is the most sensitive method for single cell RNA-seq so far. With only 0.2 M reads per cell, we can reconstruct the majority of transcriptome of bulk by using only 10 cells.
