General Interests

The main goal of my research is to conceptually unite scientific exploration of biodiversity, phylogenetic systematics and evolutionary biology to understand the processes responsible for the generation and maintenance of global biodiversity. Most of my research projects fall  within three broad areas of the biological sciences: Biodiversity, Evolution and Conservation.


Discovery, description and documentation of global species diversity through intensive fieldwork & collections based research. 

Named nearly 30 new species of amphibians and reptiles.



I use comparative methods to infer patterns and processes in trait evolution. Especially interested in the evolution of amphibian reproductive modes and anatomical adaptations to ecology.



Application of taxonomic, phylogenetic and distributional data to promote species conservation. Frequent contributor to several NGOs and governamental agencies, sharing data, expertise, text and images.

Outreach and Communication

Photography, science communication, and story telling as tools to raise awareness to the importance of the preservation of wildlife, natural habitats and natural resources.
