Jenny Visser

Jenny Visser is an Associate Professor in the Department of Internal Medicine at Erasmus MC, part of Erasmus University Rotterdam. Her research focuses on endocrinology and metabolic disorders, with particular emphasis on genetic influences on health conditions such as obesity, polycystic ovary syndrome (PCOS), and cardiometabolic diseases. She explores hormonal regulation, genetic variants, and their implications for growth, stress responses, and vascular health. Her work integrates molecular biology, epidemiology, and clinical studies to uncover mechanisms underlying complex disorders.

Key research interests include:

• Genetic determinants of metabolic traits
• Endocrine dysfunction in obesity and PCOS
• Glucocorticoid signaling and cardiovascular risk
• Vascular aging mechanisms

Notable contributions include identifying genetic variants linked to short stature and IGF-I deficiency, subtyping PCOS phenotypes, and investigating stress biomarkers in obesity. She leads collaborative projects on hormonal pathways and cardiovascular outcomes in large cohorts like Lifelines.
