Lionne Grootjen

Lionne Grootjen is a Researcher at Erasmus MC in the Department of General Practice, actively contributing to clinical and metabolic research in pediatric endocrinology. Her work centers on genetic syndromes such as Prader-Willi Syndrome (PWS) and Temple Syndrome, with a strong focus on growth hormone therapy, body composition, and energy metabolism.

Her research interests span endocrinology, genetic disorders, metabolic physiology, and pediatric rare diseases. She investigates hormonal regulation, resting energy expenditure, and nutritional transitions in PWS using advanced methodologies like indirect calorimetry and longitudinal hormone monitoring.

The recent publications reflect a consistent trend in clinical endocrinology and metabolic research, particularly in long-term growth hormone treatment outcomes, thyroid function, and cognitive effects in rare syndromes. These studies are primarily interventional and observational, often part of extended clinical trials.
