I am an aquatic microbial ecologist interested in how microbes influence human, animal, and ecosystem health through their central roles in the environment. My research explores microbial community dynamics in diverse ecosystems (from clinical contexts to the natural environment).

Recent Research Highlights

Extreme Salinity Change Governs Microbial Community Assembly and InteractionsEnvironmental Microbiology Reports, 15 February 2026.

'Salty soup': climate threat to vital lagoon ecosystemsThe Canberra Times, 1 June 2025.

Salt on the rise: What lagoon microbes reveal about the future of coastal ecosystemsEnvironment Institute, May 2025.

 ↳ Our 2025 Earth-Science Reviews paper showed the impacts of human activity and climate change are coalescing to make coastal lagoons saltier, changing the microbial life they support and the function they play in their ecosystems. Coastal lagoons, and the microbes within, are some of the planet’s most sensitive indicators of change. These ecosystems offer important opportunities for protecting biodiversity, supporting livelihoods, and securing climate co-benefits.

When a 1-in-100-year flood washed through the Coorong, it made the vital microbiome of this lagoon healthierThe Conversation, 27 Mar 2025.  
 ↳ Our 2025 Water Research study showed the 2022 Murray-Darling flood pulse cut methane production potential, boosted nutrient-removing taxa, and triggered whole-of-food-web rebounds in the internationally important and severely degraded Coorong wetland. The Conversation piece distils these findings for a general audience and explains why well-timed environmental flows are critical for wetland restoration 

Organic matter fuels methane hotspots in hypersaline lagoonsLimnology & Oceanography, Sept 2024.
↳ Our 2024 study in Limnology & Oceanography showed that fine sediment “sinks” in the Coorong stockpile organic matter, enriching methylotrophic methanogens and driving concentrated CH₄ production despite high sulfate levels (which is typically thought to suppress CH₄ in coastal environments). By linking organic matter, Archaeal community shifts and greenhouse-gas, the paper highlights an underappreciated emissions source in global Carbon budgets and the need to factor extreme lagoons into climate models.
