PhD project

The broader context of my doctoral project (and the GEco group in general) is to gain theoretical and practical insight in the field of (Species) Distribution Modelling, with a particular focus on model selection (or parameterisation) and model evaluation. In this regard, my work focuses on a systematic (theoretical simple but inherently complex) yet flexible (accessible and practical) exploration of parameter options and settings of both novel and established MaxEnt Modelling methodological practices. I have extended this comparison to include a wide range of dataset properties, modelling purpose, whilst still aiming at finding a flexible balance between simplicity and complexity, to maintain it accessible and practical. In doing so, what is emerging is a set of traceable approaches and flexible tools that integrate conceptual and practical considerations from the fields of ecology, modelling and informatics.
