Joylene Siland is a MD-PhD student and started atrial fibrillation research during her Bachelor. During her bachelor she investigated the genetic background and associated comorbidities of the initiation and progression of atrial fibrillation. Under the inspiring guidance of dr. Rienstra, prof. dr. van Gelder, and prof. dr. van der Harst she recently started a MD/PhD program. This program allows her to pursue a PhD during her master in Medicine. Her PhD include genetic studies in collaboration with the AFGen consortium. DNA samples of e.g. AF-Risk, Biomarker AF, Young AF, and PREVEND, named as the Groningen Genetic Atrial Fibrillation (GGAF) study, are analyzed to learn more about initiation, progression and treatment response of atrial fibrillation. Furthermore, she is involved in genetic studies uses data of PREVEND and Lifelines, and has several papers accepted already. She is also local coordinator of the GENETIC-AF study.
