PhD candidate

I am a PhD candidate at the department of Biological Psychology, VU University Amsterdam.

Currently (Nov-Dec 2016) I am TA for the M.Sc. Neurosciences course Behavioral Genetics, following courses on Coursera.org from the specialization "Genomic Data Sciences" offered by John Hopkins University, and working with BWA+GATK for detecting mosaicism in NGS data.

Bass player Last Thursday

I play bass (and occassionally percussion) in acoustic folk band Last Thursday. To date we have performed at numerous stages in Amsterdam including Magneet Festival, Sugar Factory and Hannekes Boom.

Guitarist Dynamic Gentlemen

I play (electric) guitar in rock cover band Dynamic Gentlemen. Our favorite spot to play gigs is 'The Waterhole' at Amsterdam Leidseplein.
