Margaret Cramm
Postdoc, QMUL Bluesky: @microbeMAC Margaret enjoys studying life at extremes. She began her research career in the Geomicrobiology group at the University of Calgary, studying the biogeography of thermophilic spore-forming bacteria and the distribution of methanotrophic bacteria and benthic megafauna near an Arctic marine methane seep. She completed her PhD at Queen Mary University of London in 2024 exploring microbial communities in Arctic permafrost and their connection to biogeochemical cycles, and is currently a postdoc on the NERC-NSF SUN SPEARS project working on microbial dynamics in Arctic soils. |

Sonia Papadaki
PhD Student, QMUL Twitter: @PapadakiSonia Sonia earned her BSc in Medical Sciences at the University of Exeter, and completed her MSc in Palaeobiology at the University of Bristol. She is fascinated by microbial life in the cryosphere and its relevance as a system to study extreme environments, the limits of life, and models for astrobiology research. Sonia's research focusses on microbial communities in Arctic endolithic environments, with particular focus on microbe-rock interactions and biosignatures. |

Laura Molares Moncayo
PhD Student, QMUL & MIO Laura Molares Moncayo earned her BSc in Molecular and Cellular Biology at Erasmus University Rotterdam (NL), and completed her MSc in Systems Biology, Genomics and Computational Biology at the École Normale Supérieure (FR). She is particularly interested in the study of extremophiles as indicators of the limits of life and how it expands our concept of the habitability of environments. Her PhD research explores the role of the atmosphere in shaping and sustaining microbial communities on glaciers. In addition to research, she is also passionate about science communication and the representation of women and ethnic minorities in science. |

Sibylle Lebert
PhD Student, MIO Sibylle earned a BSc in Humanities and Technology from the University of Technology of Compiègne, followed by a bioengineering degree from the same university in 2024. A first experience in marine microbiology in Iceland in 2021 sparked her deep interest in contributing to the preservation of Arctic ecosystems. A second internship in aeromicrobiology in Denmark strengthened her passion for research, leading her to pursue a PhD in Arctic microbiology. As part of the SIESTA project, her work explores the environmental factors that trigger bacterial ice nucleation activity in glacial habitats, along with the links between ice nucleation and dormancy as adaptive survival strategies. Since her undergraduate studies, Sibylle has been particularly interested in understanding the interplay between science, society, and human behaviour, and strives to approach research with a critical awareness of its broader implications. |

Pascaline Francelle
PhD Student (co-supervised), QMUL Twitter: @pascalinefr Pascaline completed her MSc in Freshwater and Marine Ecology at Queen Mary University of London, and interned at the National Museum of Natural History in Paris. She is fascinated by the use of genetics in ecology; from sea turtle philopatry, to phenotypic plasticity and cuttlefish olfactory systems. Now, Pascaline is part of an exciting multidisciplinary project called BioPEP (Biodegradable Plastics as emerging Environmental Pollutants), which investigates the impact of bioplastics on the environment. Her PhD focusses on the interaction between microbial communities and plastics in estuarine systems. Her primary supervisor is Dr Özge Eyice. Pascaline is specifically interested in the environmental factors influencing microbial communities’ dynamics and the biogeochemical cycles they drive. |

Jess Caughtry
PhD Student (co-supervised), UCL Jess is a PhD student funded through the London NERC Doctoral Training Programme, based at both University College London (where she is primarily supervised by Louisa Preston) and Queen Mary University of London. Previously she obtained an Oceanography Masters degree at the University of Southampton, before spending time at the European Space Agency where she further grew her passion for space science. Jess' PhD mixes environmental science with astrobiology, researching the geochemistry, physics and extremophile microbiology associated with sulphur-ice environments and applying this knowledge as an analogue for icy moons like Europa. |

Will Tallon
PhD Student (co-supervised), UEA Will earned a first-class honours degree in Biological Sciences from the University of Reading in 2022. For his final-year project, he studied bacterial colonies found within speleothems. Will was selected as one of just 20 scholars in the Critical Decade for Climate Change program. His PhD at UEA (primarily supervised by Marcela Hernández) explores the role of bacteria in Arctic soils following glacier retreat, and their influence on key processes such as soil development, climate interactions, and carbon cycling. His work centers on bacteria that oxidize carbon monoxide, a process that impacts greenhouse gas fluxes as ecosystems evolve. Utilizing a range of techniques, including gas chromatography, he examines microbial activity in soils from Svalbard, investigating how these communities shift over time and what that means for our changing climate. |

Undergraduate students: Please contact me to find out about opportunities for independent study and research in the lab.
Postgraduate & PhD students: I seek exceptional students, both academically and personally. Ideal members of the lab have a clear vision of their research goals, are enthusiastic, mature, good communicators, flexible and have a strong background in a relevant discipline.
Post-docs: I am willing to work with dedicated candidates to develop fellowship and grant proposals that would fund their work in the lab. Potential postdoctoral researchers are encouraged to contact me a year before their desired start-date, to allow time to develop these proposals.
In this lab, we judge on science and integrity, not by sex, gender, or race. Earth and environmental science, like other scientific disciplines, is and has been dominated by white faces and voices. Scientists from marginalized and under-represented groups are frequently subjected to bias while working at field sites, at meetings, in labs and classrooms, and in life. This must stop. Integrating a diverse set of experiences is critical for a comprehensive understanding of science. Discrimination and injustice, racially or otherwise, is not welcome and will not be tolerated in this space.
