She was study coordinator for a nationwide intervention trial in ADPKD and now coordinates follow-up of a national observational cohort consisting of almost 700 ADPKD patients. Her research focuses on improving current treatment with a vasopressin V2 receptor antagonist and finding markers to predict ADPKD progression. In clinical care, she sees patients with inherited cystic diseases in a specialized outpatient clinic within the expertise center in a multidisciplinary team.
