About Nathan Brown
Nathan works as an Environmental Modeller at Forest Research. He works on Tree Health issues within the physical environment group, investigating the linkages between woodland condition and the environment. He is currently using disease distribution data to reveal the role of environmental predisposition on pest and disease occurrence and conducting research to support volunteer reporting activities (Forest Lab and Observatree). Nathan returned to Forest Research in 2022, after spending 9 years working with the epidemiological modelling group at Rothamsted Research, where he was most recently involved in the SMARTIES project which investigated multiple threats to ash trees (Ash Dieback and the potential introduction of Emerald Ash Borer) across GB. Nathan has a long-standing interest in the monitoring of woodland affected by Acute Oak Decline, which began in 2009 as an MSc project with Imperial College London and Forest Research. This has continued through a PhD program and has more recently formed a component of multiple interdisciplinary research projects including BAC-STOP and Future Oak. Before this he completed a Biology BSc, at the University of Sussex, and worked as a surveyor for an arboriculture and landscape design company.
What Nathan does
Spatial modelling and data management to support tree health and soil surveys. Risk assessments for disease occurrence. Project management and funding acquisition.
