Iain's research group is interested in combining mathematical, statistical, and experimental approaches to learn about the biological world, and how we can interact with it to improve human lives. We often work on questions where "blue skies" biological knowledge can be translated into strategies to address disease and crop production. We're particularly interested in the bioenergetic organelles (mitochondria and chloroplasts) that provide the energy that powers complex life.

One major current focus of the group is EvoConBiO -- an ERC-funded project exploring the evolution and cellular control of mitochondria and chloroplasts, using approaches from stochastic modelling, bioinformatics, and molecular biology.

You can read more at the research group website, and find non-technical summaries of research papers here.

Some keywords related to our research -- mathematical: stochastic modelling, discrete population processes, inference and model selection, uncertainty quantification, pathway inference; biological: stochastic biology, cell heterogeneity, mitochondria, chloroplasts, mtDNA, cpDNA, evolution, disease progression, bioinformatics, plant systems biology.
