Silvia Radenkovic is a laboratory clinical biochemical genetics fellow at UMC Utrecht, the Netherlands and a member of Females in Mass Spectrometry (FeMS). She is currently doing a clinical fellowship where she is involved in diagnosing and helping treat patients with inborn metabolic diseases (IMD). Her research focuses on IMD such as congenital disorders of glycosylation (CDG), omics techniques such as tracer metabolomics, and different disease models.
