Research Interests

John Achermann’s research interests include:

  • adrenal and sex development
  • genetic mechanisms of disease
  • nuclear receptor biology

John Achermann’s research focuses on the mechanisms involved in adrenal and gonad (testis, ovary) development in humans. His team are trying to gain a better understanding of the factors that influence development of these organs and are investigating new conditions causing adrenal hypoplasia or disorders/differences of sex development (DSD) in children and adults. In addition to these laboratory based approaches, Professor Achermann is interested in the clinical management of DSD and in care pathways, education and support for families with these conditions.
