Projects


 My current research integrates three interconnected areas:

1.        Ecological dynamics of non-native prey and predator responses.

I investigate how non-native prey reshape the trophic ecology of native predators and whether native predator diversity can exert top-down pressure on non-native populations.

2.        Human–predator interactions.

I study how river users perceive predators and the factors that shape their tolerance, conflict, and coexistence. This work aims to inform conservation strategies that incorporate community perspectives.

3.        Tools for ecological monitoring. 

I develop morphological identification guides and non-invasive methods to support long-term monitoring of predator diets and freshwater communities. 

Monitoring of river predators and non-native prey


Since 2009, I have been collecting data on interactions between river predator species and non-native prey at the Usumacinta basin in Northern Guatemala.
