He is accredited as a Chartered Geologist and a Chartered Scientist with the Geological Society of London.

Matt is a strong advocate for greater professional development opportunities for early careers geoscientists and when not trying to visit obscure parts of the world, Matt can often be found on the golf course. He joined the founding ECN Committee in 2018 and chaired the group in 2020 and 2021.


Alex Christopher

Dan Hope
Arcadis (Geotechnics)
2020 - pres.

Dan is a Consultant at Arcadis working in the Ground Investigation team. He completed an MGeol at the University of Leicester in Applied Geology, with a focus on characterisation of metalliferous deposits. On graduation in 2019, Dan started his career in the site investigation industry as a Geotechnician before quickly progressing to a new role as an Engineering Geologist. 

Dan has since worked on a range of geotechnical projects for private industry, construction, and railway, and spent several months working at HS2 in the Colne Valley, Buckinghamshire before moving to Arcadis. Dan’s interests include hiking (especially on geological trails!), board games and visits to the pub… often all within the same day! He joined the ECN Committee in 2020, taking on the role of Regional and Specialist Group Liaison.

Ordinary Committee Members

Serdar Aldanmazlar
Geological Engineer
TRR Consultancy (Geotechnics)
2020 - pres.

Serdar is an Geological Engineer with 12 years of experience in natural construction materials research, testing and performance evaluation of built environments experience. He holds a BSc from Ankara University in Turkey and is established as a consultant in London since 2019, becoming a Fellow of Geological Society in April 2020. He is currently working as a materials and quality consultant for multiple clients from different sectors including construction, mining, and manufacturing.

His professional interests include the use of recycled aggregates, physical and chemical interactions between naturally occurring and industrial byproduct aggregates and binders such as bitumen and Portland Cement, as well as short and long-term damage mitigation caused by minerals in built environments. He joined the ECN Committee in 2020.

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

Simon joined the ECN in the Christmas party season of 2019 and was elected to the committee by March 2020. 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.
