Annelies Focquaert graduated in 2001 in the class of Joris Verdin at the Royal Conservatoire of Antwerp. After she received her laureate in 2006 from the Orpheus Institute in Ghent with a research project on the Belgian organist Jacques-Nicolas Lemmens, she successfully defended her doctorate in the arts in October 2014 about the same composer (Associative faculty of the University of Antwerp - Artesis Plantijn Hogeschool).
After an assignment as project coordinator for the Organ in Flanders vzw, she has been working as a scientific assistant at the Study Center for Flemish Music vzw in Antwerp since 2005. Currently she teaches organ, harpsichord and accompaniment practice at the academies of Antwerp and Hemiksem.
In addition to several organ concerts in France and Belgium, she also provided accompaniment on organ or on harmonium of choirs and ensembles such as the Vlaams Radio Koor and Vlaams Radio Orkest, the Choeur de Namur, Prometheus Ensemble and Oxalys ensemble.
On the occasion of the opening of the exhibition 450 years City Hall Antwerp (February 2015), she played on the newly restored Mustel harmonium.
