I am fascinated by the evolutionary mechanisms that shape the natural world, more specifically by what happens when species become threatened or populations become isolated. When species adapt to their changing environments, it sometimes happens that nature, oddly enough, "fools" itself as a result of basic, evolutionary principles. As a PhD candidate I therefore work on explaining how a weird, evolutionary flaw in crested and marbled newts (genus Triturus) evolved. My project is a collaboration between Naturalis and the Institute of Biology Leiden (IBL).

Balanced
Lethal Systems

Photo of a crested newtI am a member of the Wielstra lab (ERC Starting Grant-funded research), where we study the genomics underlying the best-known case of a balanced lethal system: chromosome 1 syndrome in Triturus newts. Balanced lethal systems are considered an evolutionary failure, because natural selection is unable to get rid of the associated recessive, lethal alleles. I investigate the lethality and evolutionary origin of this system in collaboration with IBL. Are you curious to find out more? Just click here to read about balanced lethal systems!

What is it actually like to work as a PhD in the field of genomics, for both Naturalis and the University of Leiden? And what do I learn from salamanders?
