Joining Spotify

Last week was my last at DPG Media, after a ride of almost 4 years. I’m thankful for the company and the people there (in particular Philippe RemarqueMarten BlankesteijnPaul Vereijken) that allowed me to do what I did: growing a team focussing on personalization.

This awesome team is what I’ll miss most: Lucas de HaasMarlies van der WeesAron HammondGijs MolenaarNathan DeraveGee Yeol NahmGert-Jan BraeckeveltNicholas Leo MartinRosa Maria SiervoDorian BrownIvo VelthovenManali M.Miguel Panelo, Stas Yuzidski, André Carvalho, Mischa MolhoekAstrid Weijs, and of course Erik Terpstra.
Thanks for the great time, and everything I learned from you. I know the product is in good hands with you.

I’m very very excited about what’s next! Next week I’ll be starting as Engineering Manager at Spotify within the search team. I can’t wait to get to know the company and my new colleagues!
In the new year, the search team will be expanding substantially, so keep an eye out for vacancies!

TREC OpenSearch proposal accepted

trecopensearch-darkerOur TREC proposal for OpenSearch has been accepted! TREC OpenSearch will be run in a the same vein as CLEF LL4IR and use the same infrastructure.

OpenSearch is a new evaluation paradigm for IR. The experimentation platform is an existing search engine. Researchers have the opportunity to replace components of this search engine and evaluate these components using interactions with real, unsuspecting users of this search engine.
