Professional biography

I am a microbiology PDRA working in the AstrobiologyOU group. My research currently involves investigating the diversity and activity of microbial communities inhabiting extreme environments that are analogous to Mars and Enceladus. I also perform simulation experiments to assess the growth dynamics and survival of microbes in simulated extra-terrestrial conditions. 

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 stable isotope probing to identify the active organisms.

Earth and Space Exploration Program 2022: Microbiology in Ladakh

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.
