Synthetic Biology & Cellular Control Laboratory (web)
The Synthetic Biology and Cellular Control lab works on two broad topics: synthetic biology (design and construction of novel cellular devices in living cells, to alter and control their behaviour) and systems biology (the dynamics and behaviour of cells and cellular networks).
To date, our own wet lab work is exclusively in microorganisms (bacteria and yeast) and we are pursuing mammalian cell work through collaboration. The rapidly growing field of synthetic biology represents an effort to implement engineering at the cellular level.
We are developing novel regulatory network architectures and new biological “parts” to accomplish a variety of goals. Often our work takes the form of simple proof-of-concept demonstrations, but we are increasingly interested in the potential of synthetic biology to address real-world issues.
We are actively engaging with private and public sector partners to learn about key problems that we can use as inspiration for our research direction.
Examples of applied projects include efforts at developing systems to: detect disease microorganisms and respond to counter them; develop robust microorganism-based biosensors for blood assays; and designing sense-and-respond bacteria to ameliorate inflammatory bowel disease.
Our experimental work is accompanied and guided by systems biological modelling at various levels, from detailed biochemical kinetic models (stochastic or deterministic) to higher-level approaches inspired by control theory.
