Seino Jongkees is associate professor in the department of Chemistry and Pharmaceutical Sciences at VU Amsterdam. He received his PhD in 2013 from the University of British Columbia under prof. Stephen Withers, studying the mechanisms of carbohydrate-active enzymes, then proceeded to a JSPS post-doctoral fellowship at the University of Tokyo under prof. Hiroaki Suga, studying mRNA display of macrocyclic peptides. He started his independent career in a tenure-track position at Utrecht University in 2016, moving to a permanent position at VU Amsterdam in 2021. His research focuses on high throughput approaches for discovery of new peptide and peptidomimetic drug candidates, using a combination of mRNA display, genetic code reprogramming, and chemoselective peptide modification.
