Microfluidic based high content screening of cells embedded in 3D hydrogels provides a powerful alternative to traditional suspension or 2D culture methods, offering higher quality cell populations at lower cost. Our collaborative team has engineered high throughput microchip platforms where single cells can be live imaged to track stem cell expansion in 3D hydrogels, creating the first 3D hematopoietic stem cell (HSC) platforms. This project seeks to advance that foundation by building a next generation high throughput screening pipeline that integrates microfluidic live cell imaging and experimental data with computational modeling and machine learning. By constructing mathematical representations of the underlying biological processes, we can simulate and predict culture dynamics, quantify key variables, and map the interactions between process indicators and control parameters. Such insights will support more rational process design and optimization, improve control strategies, and reduce the need for repetitive experimental trials.
Aims: 1. Develop mechanistic, machine learning based, and hybrid models to investigate cell proliferation within hydrogels, coupled with live cell imaging data (image processing). 2. Employ process systems engineering approaches, including surrogate modeling, process monitoring, optimization, and control, to enhance cell production, improving efficiency while reducing costs. 3. Experimentally validate computational predictions using custom designed microfluidic chip platforms.
Methodology: 1. At IIT Delhi, computational frameworks will be established to capture the key factors influencing cell growth and to predict optimal culture strategies. Advanced ML methods, guided by biological insight, will be explored alongside mechanistic models. A process monitoring and optimization framework will be developed to track and refine critical process variables. 2. At UQ, the student will receive experimental training and perform data collection using microfluidic chip systems. The computational predictions will be tested and validated experimentally in close collaboration with UQ researchers.
