Bart van der Sanden is a postdoctoral researcher in the Genomic Technologies research group of Prof. Alexander Hoischen at Radboudumc in Nijmegen. He obtained his PhD from Radboudumc, where he investigated hidden variants and non-coding variation. In his postdoctoral research, he focuses on advancing genomic technologies for rare disease diagnostics, with an emphasis on long-read sequencing and optical genome mapping. Additionally, he is involved in the ERDERA project, which seeks to advance rare disease research in Europe, including the integration of long-read technologies.
