Dr. Simon Groom
Consultant Geological Engineer
Fugro (Geotechnics)
2020 - pres.

Simon joined the ECN in the Christmas party season of 2019 and was elected in Q1 of the following year. He comes quite late to the site investigation industry (August 2021), where his time is currently dominated by the HS2 project, having had previous careers in laboratory instrumentation, academic research and teaching, and most recently independent research. He doesn’t like to limit himself to one applied specialism, having worked in field volcanology, petrology, material characterisation and archaeology.

Simon has been based in and around London and the South East for most of his career, working out of Birkbeck, University of London, University College London, and now Fugro in Wallingford. He joined the ECN because while London has several diverse and active geoscience communities, in economic geology, site investigation, outreach and recreational geoscience, they appeared to him quite disparate, and it remains difficult for an early career geoscientist to lock into these communities, contribute to them and see and build on their options. He believes the ECN can provide key forum in this space, joining the ECN Committee in 2020.

Ayesha Landon-Browne
PhD Student
Cambridge University (Academia)
2021 - pres.

Ayesha currently splits her time as a PhD Student at the University of Cambridge and working as an Exploration Geologist in northern Canada. Her academic research is focusing on the use of Pt and Fe stable isotopes on Archean komatiites to further understand early Earth processes including core formation, the late veneer and the delivery of siderophile elements to Earth and the early mantle. Her work as an exploration geologist has taken her to remote parts of British Columbia where she has worked on a porphyry gold deposit and most recently in the Yukon at a Ag-Pb-Zn deposit.

Prior to starting her PhD, Ayesha completed a BSc in Chemistry and Earth Sciences at Carleton University and an MSc in Earth Sciences at the University of Ottawa. When she is not in the field or the lab Ayesha likes to go backcountry hiking, probably has a knitting project on the go and making plans to explore the UK, and hopefully Europe. She joined the ECN Committee in 2021.

Joceyln Barker
Senior Associate
PwC (Sustainability)
2023 - pres.

Jocelyn currently works as a Net Zero Transformation Consultant at PwC, with a focus on scope 3 emissions and decarbonising the supply chain. She has worked with major oil and gas clients, central government departments and agriculture. As part of her role, Jocelyn stays up to date with the latest news and regulations within the climate space, understanding how best to influence industry to decarbonise and future proof themselves against climate change.

As someone early in her career journey, Jocelyn is at the same stage as many new ECN members, and believes the forum is so important to knowledge-share, advocate for new career geologists, and open avenues for professional development. Jocelyn graduated from the University of Oxford with an MEarth Sciences; she is a keen cook, walker and rugby fan (having played throughout university). She joined the committee in 2023.
