Niki Karavitaki is Clinical Associate Professor in Endocrinology and Honorary Consultant Endocrinologist at the Queen Elizabeth Hospital Birmingham where she co-leads the Pituitary Service and Pituitary MDT.

Her research and clinical interests focus on hypothalamo-pituitary disease (particularly sellar and parasellar tumours and hypopituitarism) covering pathogenesis, management and long-term outcomes and expanding to the identification of biomarkers of diagnostic and prognostic significance with “omics” techniques. 

She has extensively published on her field and is a sought after lecturer in national and international meetings. 

Niki Karavitaki on the risk of brain tumours after radiotherapy for pituitary adenoma

Niki Karavitaki talks with The Lancet Diabetes & Endocrinology about the risk of a second brain tumour after radiotherapy for pituitary adenoma or craniopharyngioma.

Niki Karavitaki completed her training in endocrinology, diabetes and metabolism in Athens in 2002. She had been previously awarded a Master’s degree in neuroendocrinology with distinction under Professor Julia Buckingham at the Imperial College of Science, Technology and Medicine (University of London). In 2003, she moved to the Oxford Centre for Diabetes, Endocrinology and Metabolism supported by grants from the Greek Endocrine Society and the University of Athens, where she worked as a Research Fellow in Clinical Neuroendocrinology under Professor John Wass for 3 years. 

Between 2006 and 2015, she was a Consultant Endocrinologist at the Oxford Centre for Diabetes, Endocrinology and Metabolism; during this period, she expanded her research portfolio on hypothalamo-pituitary disease (particularly tumours and hypopituitarism) covering the areas of pathogenesis, management and long-term outcomes. In 2013, she became an Honorary Senior Clinical Lecturer in Endocrinology at the University of Oxford.

In 2015, she moved to the Institute of Metabolism and Systems Research (IMSR) at the University of Birmingham where she leads the Pituitary theme.  She has established national and international collaborations and she is actively involved with patient support groups and with national/international bodies and societies. She is the Lead of the Academic Clinical Training in Endocrinology and Diabetes at the University of Birmingham and the IMSR Lead for Continuous Professional Development. Since 2021, she is the Research and Education Lead at the Centre for Endocrinology, Diabetes and Metabolism (CEDAM).
