Research Interests

My research interest revolves around the microbiological aspects of greenhouse gas turnover in widespread environments. Current research focus includes using methanotrophy as a model system to address questions in: 

 (i) Microbial Life Strategies:

On-going research address the remarkable resilience of methanotrophs to environmental stress / cues as anticipated under climate and land-use change scenarios. The findings from these studies were subsequently used as a basis for a meta-analysis to adopt and develop a conceptual framework for microbial life strategies (Competitor-Ruderal- Stress tolerator framework). Please see:

 (ii) Microbial Interaction:

Microorganisms rarely live in seclusion and thrive in the presence of other interacting partners, forming intricate relationships with synergistic, antagonistic, and neutral endgames. Therefore, the actions of a concerted community can be significantly higher than the combined effects of individual microorganisms. Using synthetic and methane-enriched communities, on-going studies address the role and relevance of the microbial ‘interactome’ in modulating community functioning. Please see:

 (iii) Putting Microbes to Work:

Bridging fundamental research to biotechnological applications, my team and I harnessed the methanotrophs for potential real-world applications. On-going work include optimizing the use of bio-based residues from various waste streams as soil additives to minimise greenhouse gas emissions in agricultural landscapes. Please see:
