About
Assimila uses satellite data and weather information to address real world problems.
We help our customers understand, monitor and predict the environment – agriculture, land, and climate risks are our particular focus areas.
Formed in 2006, the company was founded on the principles of combining deep domain knowledge of Earth observation systems, with professional consultancy skills, to support our clients make the best use of EO data. We have grown our offering since then, developing R&D programmes and information solutions to offer practical solutions.
We work closely with leading universities to translate cutting edge research into practical applications, developing innovative techniques to transform data into useful information for sustainable environmental management. We build tools and applications for operational systems; and provide consultancy services for our customers to help them make the best use of environmental data and models. We emphasise a physical modelling approach and understanding of environmental processes.

With an extensive network of contacts and a track record of successful projects, Andy provides informed insights into the complex world of satellite Earth observation, offering fresh ideas and strategic advice to a range of clients. Andy is currently Director and Principal Consultant at Assimila and is also Space Programme Director for Resilience Constellation Management, a start-up seeking to develop geospatial solutions to climate resilience challenges for government and commercial clients worldwide.
Gerardo Lopez-Saldana
Gerardo is Assimila's Technical Director. His work is focused on the use of Earth observation data, geocomputing and data assimilation methods to characterise the land surface. His main research interests are fire in the Earth system and the Carbon cycle. Some of his previous work includes:
Developing an operational wildfire monitoring system using direct readout EO data for Mexico and Germany.
Working at UCL as part of the ESA-GlobAlbedo team, helped to create the longest land surface Albedo data record. As part of the FP7 MELODIES project at the University of Reading developed a methodology to improve greenhouse gas emission inventories, through novel use of Earth observation for assessing annual land cover and land use changes.
Nicola Pounder
Nicola has worked in Earth observation since obtaining her DPhil in physics from the University of Oxford in 2008. She has more than a decade of research experience at the Universities of Oxford and Reading and joined Assimila in 2014. Nicola is experienced in applying advanced statistical techniques to the analysis of large datasets through software algorithm development. Her recent work has been in Earth observation of both the land and atmosphere in particular exploiting satellite instrument synergies through variational data assimilation techniques. She has worked in international collaborations including the Collider Detector Facility (CDF) experiment at the Fermi National Accelerator Facility, Chicago, USA and as part of synergy project development for the ESA-JAXA EarthCARE satellite, presenting her work at national and international conferences.
Emma Klingaman
Emma is an experienced meteorologist with expertise in areas including weather forecasting, climate change, aviation and renewable energy. She has worked in meteorological research and data analysis since gaining her PhD in meteorology from the University of Reading in 2010. Her postdoctoral research focussed on the aviation industry and in particular its climate impact. More recently she worked on developing short-range forecasting systems for renewable energy applications. Emma joined Assimila in 2024, providing meteorological expertise to a range of projects including consulting, assessing wildfire hazard for the insurance industry and crop yield forecasting.
Alex Cornelius
After completing his masters in Remote Sensing from UCL, Alex joined Assimila to work on operationalising a system to help the adoption of biopesticide use in China. Since then, he has been involved in a wide range of projects that integrate different types of Earth observation, using his background in Environmental Science to apply Earth observation in monitoring and forecasting systems to further global agricultural sustainability. His current work at Assimila involves integrating Earth observation data with biophysical crop models to increase nitrogen use efficiency in winter wheat across the UK, as well as developing deep learning models to derive pasture grass biomass estimates from synthetic aperture radar data.
Ian Jory
Ian is an accomplished professional Project Manager, is Prince 2 certified, and has over 30 years' experience in a variety of sectors including space, law, manufacturing, and telecoms. Ian has delivered many new technology and business change projects, both in the UK and internationally, to the highest possible standards. Ian has spent over half of his career working in the space industry and since returning to Earth observation, and joining Assimila, Ian has been responsible for managing a range of projects including the use of satellite data with crop modelling as well as pest and disease monitoring.
Josie Mahony
With 11 years of study and research in the field of environmental science, focusing on a wide range of topics, including climate science, oceanography, environmental chemistry and mathematical ecology, Josie brings a wealth of experience and skills to the Assimila project portfolio. Josie has a BSc in oceanography, a Masters by Research degree in bioremediation and more recently a DPhil from University of Oxford modelling the impact of climate change on the wildebeest of the Serengeti. Her research covered process-based climate model evaluation and the use of climate data to drive spatially explicit ecological models. In addition, Josie also researched the use of meteorological forecast data to predict the risk of dengue fever outbreaks for the Red Cross Red Crescent Climate Centre.
Yara Al Sarrouh
Yara is an Earth Observation Application Scientist. She employs an interdisciplinary approach to facilitate the translation of Earth Observation (EO) data into practical applications across various sectors such as financial services, research, scientific analysis, and agriculture services. In doing so, she effectively bridges the gap between EO expertise and the needs of end-users. Yara has a Bachelor of Science inAgriculture from the American University of Beirut, where she specialized in hydrology and irrigation management. Her academic journey was further enriched by the Said Foundation Scholarship, which enabled her to pursue a Master's degree in Remote Sensing and Environmental Mapping at University College London.
