Introduction
I have recently completed my PhD based at the ZSL Institute of Zoology and UCL. My project focused on investigating hatching failure in managed and wild threatened bird populations, distinguishing the factors leading to infertility and early embryo death in these populations and examining the management techniques and egg manipulation procedures which are utilised to maximise hatching success.
More broadly, I am interested in behavioural ecology, evidence-based conservation, and sustainability.

Avian hatching failure is a widespread phenomenon, affecting around 10% of all eggs that are laid and not lost to predation, damage, or desertion. Our understanding of hatching failure is limited in terms of both its underpinning mechanisms and its occurrence across different populations. It is widely acknowledged that rates of hatching failure are...
Reproductive failure is ubiquitous. However, research on the mechanisms underpinning reproductive failure is still lacking in most species. This gap in our understanding has particularly strong repercussions for threatened species and it hinders our ability to establish effective interventions to improve survival. In this review, we focus on why eg...
Analyses of phenotypic integration and modularity seek to quantify levels of covariation among traits to identify their shared functional, developmental and genetic underpinnings ('integration'), which may delineate semi-independent subsets of highly integrated traits ('modules'). Existing studies have focused mainly on mammals or model organisms,...
Ecosystem collapse, i.e. the endpoint of ecosystem decline, is a central concept of IUCN Red List of Ecosystems (RLE) assessments and the identification of ecosystems most vulnerable to global environmental change. Estimating collapse risk can be challenging for ecosystems reliant on a few dominant species to perform most of their functions because...
