About the Project

Future manufacturing of chemicals, fuels, energy, materials, and drug therapeutics will be circular, sustainable, and biological at its heart. Microbes are increasingly applied as cellular factories for manufacturing from bio-based or renewable energy and carbon feedstocks. However, Nature has not evolved microbes for industrial-scale applications. More often than not, the properties of microbes (e.g., carbon repertoire, tolerance to inhibitors) would require fine-tuning in order to develop economically viable bioprocesses.

Adaptive laboratory evolution (ALE) is a proven technique for microbial optimization, leveraging the power of evolution (i.e., Survival of the Fittest). Through genome sequencing of adapted strains, it also generates big data directly contributing to our understanding of the rules of life. However, ALE can be slow and resource intensive. In this project, the candidate can choose to tackle this challenge from either an engineering or a biological angle. The former involves developing novel microbial cultivation system and software to advance ALE. The latter concerns developing novel molecular biology tools to create genetic diversity for evolution.

During the project, the candidate will receive training at the interface of engineering and biological sciences. The candidate will gain expertise in the areas of industrial biotechnology. The candidate will also benefit from the resources, supports, and training from the Engineering Graduate School, the Faculty and the Departmental Employability Teams, allowing the candidate to develop themselves into a future leader in bioeconomy.
