Gaby Deckmyn

Environmental & Ecological Modeller

More than 20 years of experience developing process-based models that describe and predict complex above- and below-ground processes in agricultural and natural ecosystems. Strong track record in scientific publishing (H-index 29), with a focus on getting the logic of model systems correct.

Profile

Scientific rigour, practical model design.

Gaby specialises in process-based models for agricultural and natural ecosystems. A quick learner with wide interest in ecology and agriculture and a love of mathematical equations, she has helped students develop models on many topics and tools as lecturer of the course Ecological modelling. She specialises in getting the logic of the model system correct, while data flow and optimal coding are typically developed together with her partner Gert Cauwenberg.

Her work helps research teams and organisations investigate complex systems, evaluate scenarios and derive insights from scientific data — currently including soil carbon modelling for carbon credits.
