I am a palaeontologist fascinated by mammal diversity through time. I am particularly interested in the effects of climate change, competition, and extinctions on mammal diversity over millions of years. My research focuses on fossil mammals from Africa and South America. I use fieldwork, microCT scans of fossil teeth, and phylogenetic comparative methods.

My research is funded by the NWO (Dutch Research Council) through a VENI grant titled 'Extinction as a reset button: Quantifying mammalian diversification through global climate change'.
VENI project: In the future, climate change is predicted to be a major contributor to biodiversity loss, which is alarming. Slow-growing animals, such as mammals, are particularly affected by this. 34 million years ago, global climate changed abruptly and disruptively. We know this profoundly impacted mammals in the northern hemisphere. But how were southern mammals affected, including those in the tropics? By studying fossil mammals from the Southern hemisphere, I will quantify their responses to climate change, the long-term effects of this, and identify ecological factors driving subsequent recovery. My results will provide global, long-term insights into mammalian response to climate change.

CurrentTopics
A selection of the topics I am working on currently:
- Marsupial dental topography and its relation to diet
- Diversification of South American native ungulates (or 'SANUs')
- Undescribed mammal fossils from fieldwork in Kenya
- Undescribed mammal fossils from fieldwork in Peru
