John Achermann

John Achermann - Endocrinology


John trained in medicine in Cambridge (1991, MB), paediatric endocrinology in London (1997, MD) and molecular biology in Chicago, USA (1998-2001, PhD). His interests include human adrenal and sex development and endocrine genetics. Since 2006, he has been a Wellcome Trust Senior Fellow at UCL Great Ormond Street Institute of Child Health and has around 200 publications. He is passionate about football - the beautiful game.


  • Differences in sex development
  • Congenital adrenal hypoplasia

Research interests

John’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, he is interested in the clinical management of DSD and in care pathways, education and support for families with these conditions.

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