“He smiles a lot. But I think there might be worms inside him making him smile.”
— Stephen King [The Strand]

I've been studying worms...

 

My research has three major focus areas all combining traditional organismic biology, advanced morphology and bioimaging with transcriptomics and phylogenomics.

  • Chaetogenesis: I use serial TEM, immuno-histochemistry CLSM to describe the cellular mechanisms of chaetae formation in annelids while investigating the molecular underpinnings of this intricate process with transcriptomics and differential gene expression studies.

  • Phylogenomics: I use phylotranscriptomics and targeted sequence capture to uncover the evolutionary relationships of marine invertebrates (mainly annelids).

  • Integrative Taxonomy: I use a combination of advanced bioimaging techniques (e.g. µCT, serial histology, SEM) and molecular species delimitation methods to describe new taxa.
