What I do

Turning 3D sensing into trusted forest measurements.

I'm an Earth observation scientist at UCL working to make three-dimensional forest measurement practical beyond the research lab. Over the past decade, I've worked with many laser scanning systems, from terrestrial and mobile LiDAR to UAV and smartphone sensors, and learned that no single technology is the answer. Reliable measurements come from the entire pipeline: designing sensors, collecting data, benchmarking hardware and software, developing processing workflows, and working with foresters, ecologists and city managers to ensure the results answer real-world questions. My goal is to turn emerging technologies into trusted, affordable and open solutions that anyone can use to understand forests better.

End-to-end expertiseWorking across the complete measurement pipeline: prototype development, field acquisition, benchmarking, processing, ecological interpretation and operational deployment.
International benchmarksLeading independent evaluations of forest scanning technologies and processing pipelines, helping researchers and practitioners choose methods based on evidence rather than marketing.
Building global expertiseDesigned and delivered more than 10 international summer schools and workshops, training hundreds of researchers, practitioners and students from around the world in modern forest measurement and Earth observation.
Open science & standardsChairing 3DForEcoTech (500+ scientists across 60+ countries) and pushing open data, shared protocols and reproducible workflows so results are comparable, not siloed. UCL Open Science Award, 2025.

In the field this season.

One method — low-cost 3D scanning — carried from UK inventory plots to city streets and tropical community forests.

3D Urban Tree Intelligence

In June we ran a city-scale scanning testbed in Bratislava — 28 scanners capturing 1,000+ trees. We're now aligning, clipping and cleaning the data and preparing the evidence and evaluation, all due this summer.

Flux-tower footprint — Alice Holt

Mapping the ~2.5 ha footprint beneath a carbon flux tower in 3D, linking what the tower measures to the structure behind it.
