Overview

Roger A.H. Adan is affiliated with Utrecht University in the Netherlands, focusing primarily on neuroscience and medicine. Their research spans multiple subfields including endocrine and autonomic systems, cellular and molecular neuroscience, clinical psychology, molecular biology, and nutrition and dietetics.

The primary topics of their work include regulation of appetite and obesity, biochemical analysis and sensing techniques, neurotransmitter receptor influence on behavior, eating disorders and behaviors, receptor mechanisms and signaling, genetic associations and epidemiology, and obesity, physical activity, and diet.

They have contributed frequently to the following publication venues:

  • bioRxiv (Cold Spring Harbor Laboratory)
  • Neuroscience Applied
  • Psychopharmacology
  • European Neuropsychopharmacology
  • Nature Communications

Several recent papers illustrate the range of their research interests and collaborations:

  • Genetic identification of cell types underlying brain complex traits yields insights into the etiology of Parkinson's disease, 2020, Nature Genetics
  • The melanocortin pathway and energy homeostasis: From discovery to obesity therapy, 2021, Molecular Metabolism
  • Tolerable upper intake level for dietary sugars, 2022, EFSA Journal
  • Temporally Specific Roles of Ventral Tegmental Area Projections to the Nucleus Accumbens and Prefrontal Cortex in Attention and Impulse Control, 2021, Journal of Neuroscience

Frequent collaborators include:

  • Mieneke C. M. Luijendijk
  • Suzanne L. Dickson
  • Frank J. Meye
  • Louk J. M. J. Vanderschuren
  • Iris Stoltenborg

The breadth of their work is reflected in the volume of publications within neuroscience (74) and medicine (40), demonstrating a cross-disciplinary approach. Their focus on cellular mechanisms and behavioral outcomes aligns with ongoing research themes in metabolic regulation, appetite control, and neuropsychopharmacology.
