I am a Lecturer in Microbiology within EEES and AstrobiologyOU. My research involves investigating the diversity and activity of microbial communities inhabiting extreme environments and simulated martian environments to build our understanding of habitability and the metabolisms that fuel growth and survival at the limits of Life. I am also interested in exploring these extremophiles to develop societal benefits, employing their unique metabolisms to combat pollution, climate change, and antimicrobial resistance. My PhD at the University of East Anglia involved characterising the impact of plant growth on trace gas metabolising microbes in the soil environment, with a focus on C1-metabolising microbes and stable isotope probing to identify the active organisms.

My current research interest include identifying the limits of life in extreme environments, cleanrooms, and simulated extraterrestrial environments. I am also investigating potential applications of this research through the OU's Open Societal Challenge Scheme. My other interests include evolutionary biology, taxonomy and environmental science.
OSC - Extremophiles Against Antibiotic Resistance EAAR - The vision of this project is to develop a toolkit to identify novel antibiotics in extreme environments to use in the fight against antibiotic resistance. Extreme environments harbour unique microbes, but their remoteness and complexity have resulted in them being overlooked and there is a high-potential for novel chemistries and genes to be abundant in non-standard environments. Working with the Worcestershire council, we have been able to sample from the historic salt brines of Droitwich Spa - using these brine samples we were able to isolate a range of novel salt-adapted microbes. These microbes have been shown to suppress the growth of various hospital associated pathogens, including MSRA, and we are now focussed on identifying the chemistry of the compounds driving this antibacterial activity.
OSC - SPLICE: Sustainable Processes Linked for an Integrated Circular Economy - This Challenge aims to combat environmental contamination and economic losses due to unsustainable waste management by providing full-system solutions to recover, recycle, and generate valuable materials and energy from wastes. The project aims to accelerate societal change towards reimagining wastes as sources of energy and valuable resources. We have been able to identify a range of microbial isolates capable of capturing metals and breaking down dyes from textile wastewater and are currently investigating other potential applications of extremophiles in reducing environmental pollution.

I was an international scientific advisor on the Earth and Space Exploration Program with NASA Blue Marble Institute, Mars Society Australia, and the Amity Centre for Excellence in Astrobiology.
I am a visiting lecturer at Amity University Mumbai and Amity Centre for Excellence in Astrobiology, where I lecture on the microbiology of extreme environments for the Masters in Astrobiology course.

We plan to provide a course that teaches Indian postgraduate students microbiological and geological techniques at field sites within the Tso Kar region of Ladakh. This training will be provided to groups of students by a team of twelve academics on rotation. This course will be a combination of online lectures and practical work in the field, with the characterisation of samples collected from the multiple sites of scientific interest being developed into research manuscripts. A key component of the microbiological work will be screening for isolates that produce antimicrobial compounds, taking inspiration from the small world initiative, as extreme environments potentially represent a reservoir of undiscovered antimicrobial agents. |
