We study the continuous flow microfluidic system for single cell analysis for precision medicine. Single-cell analysis is important for understanding bio-processes in a physiological system. However, without proper systems engineering, it remains challenging to manipulate individual cells effectively to obtain meaningful statistical data indicating cell heterogeneity. To address the correlation between single cell analysis and diagnosis, the development of a rapid high throughput screening platform is essential. Based on droplet encapsulation of single cells, a continuous flow microfluidic system can be used as a functional flow cytometer to characterize single cell signals (such as enzyme secretion, product generation and morphology) comprehensively for quantitative biology, without limiting by surface biomarker labelling. The efficiency of this system is to screen ~1000 cells/second. Primary patient samples can be characterized rapidly for personalized therapeutics on time, without relying on cell culturing models. This system also allows us to indicate the correlation between phenotype and genotype of individual mutant cells for high throughput data-driven engineering biology. We also investigate functional soft materials (such as gradient porous hydrogels) as the fluidic components to manipulate fluidic distribution in the micro-channels for desirable cell encapsulation and screening with on-demand fashion.

The Technology Innovations for Systems Biology laboratory aims to develop tools to better understand biological systems and address healthcare issues. We develop technology platforms and novel molecular biology techniques to perform precision measurements of multiple modalities (e.g. genetic, epigenetic, transcriptomics) in individual cells, as a basis for understanding human health and diagnosing, monitoring and treating diseases. We also invent innovative technologies for bio-sample preparation and disease diagnosis to meet the evolving healthcare needs of society.
John Jia En CHUA (Interactomics and Intracellular Trafficking Lab)
Neurons communicate via synapses to generate cellular responses that form the basis of our ability to learn, remember and express emotions. Transport of synaptic proteins by intracellular transport plays essential roles in synaptic function. We couple gene manipulation strategies such as CRISPR and shRNA with live imaging and microfluidics to study mechanisms of synaptic transport in neurons. In doing so, we seek to understand how impaired transport can lead to synaptic defects that culminate in neurological disorders. We are also keen to identify biomarkers suitable for the early detection of neurodegeneration.
Alfredo FRANCO-OBREGON (BICEPS Lab)
Research Associate Professor
BioIonic Currents Electromagnetic Pulsing Systems: The BICEPS laboratory bridges sate of the art engineering with clinical medicine and has the mandate of designing cutting edge technologies to enhance the function and improve the metabolic benefit of muscle and the body’s stem cell pools which, in turn, will benefit heart health, stimulate joint regeneration, enhance fat burning, improve brain function and slow mental aging in the ill, physically compromised and elderly. We have recently developed a novel set of non-invasive technologies to awaken the body’s regenerative drive with as little as 10 minutes treatment per week that will truly represent a paradigm shift in how modern medicine approaches preventative medicine and rehabilitation post surgery. These technologies also help the body fight common and dangerous cancers such as breast, colorectal, gastric and prostate. Some of our cutting edge technologies are currently being tested in human clinical trials with very promising results. The BICEPS lab will lead the world in the design and use of such technologies in the global fight against the wraths of metabolic diseases and aging.

Our group’s research consists of three parts; in vivo microcirculation, computational simulation, and in vitro microfluidics. We utilize an acute rodent model for microcirculation studies. In vivo microhemodynamic study provides us insightful information on how the abnormal alterations in blood property potentially impair microcirculatory functions. This study can be a part of the basic science leading to the future development of a therapeutic strategy for cardiovascular diseases. We also develop computational models to study the cell dynamics using the lattice Boltzmann method and immersed boundary method. In this simulation study, we aim to examine the effects of cell aggregability and deformability on blood flow in microcirculation. In order to study on physical or biochemical property changes in blood under pathological conditions, we develop a novel microfluidic device for quantification of the blood property at the single-cell level.
