From climate ambition to real outcomes.

I advance climate and ecosystem science to make sure our environmental commitments deliver for nature and people.

Research themes

Climate change is intensifying faster than our response. We need to scale up action that works.

Nature

Ecosystem resilience & tipping points

Forests recover from stress, until they can’t.

Detecting the critical slowing down before a forest tips, and mapping where the risk concentrates across the tropics.

People

Socio-ecological sustainability

Helping people and ecosystems at once, and seeing who pays.

Finding where nature-based solutions genuinely work, and how their benefits and burdens are distributed.

Policy

Climate policies & actions

Carbon markets make promises. Can the evidence support them?

Stress-testing additionality, leakage, and permanence to find which instruments deliver durable outcomes.

Research methods

A quantitative toolkit, from satellite to causal model.

I combine large-scale Earth observation with rigorous causal methods, so a claim about a forest, a carbon project, or a policy can be tested against what would have happened otherwise.

EO · Remote sensing
Satellite Earth observation
Optical and radar composites (Sentinel, Landsat, MODIS) to measure forest state and change.
Dynamics
Earth-system modelling
Machine learning and physics models to understand earth system process. Resilience indicators and critical slowing down detection from dynamical systems theory.
Identification
Causal inference
Counterfactual and quasi-experimental evaluation to isolate real effects from baselines.
Ground truth
Field data & local knowledge
Ground truth to anchor and validate the satellite and model layers.

My research has informed governments and global institutions, and just as meaningfully, the communities living closest to the forests it studies.
