Tanja Zijp

Tanja Zijp is a Researcher at the Department of Clinical Pharmacy and Pharmacology, University Medical Center Groningen (UMCG), University of Groningen, holding an MSc and PhD (dr.) with active contributions to clinical pharmacology and therapeutic drug monitoring.

Her research centers on innovative adherence monitoring through hair analysis for tacrolimus in transplant patients and inhaled respiratory medications, alongside investigations into pharmacokinetic variations from physiological changes (e.g., menopause) and drug formulation differences. Key interests include optimizing immunosuppressant therapy, validating alternative biological matrices, and improving clinical interpretation of drug exposure data.

Recent publications (2024-2025) reveal a concentrated effort on translating analytical methods into clinical practice—particularly hair-based adherence assessment for respiratory therapies and tacrolimus monitoring—while addressing critical gaps in formulation interchangeability and quality-of-life correlations in transplant recipients.
