Personal biography

Professor Andrew Nicholson is a consultant histopathologist specialising in thoracic pathology, and an honorary professor of respiratory pathology at the National Heart and Lung Institute, Imperial College London. He has particular expertise in thoracic pathology (lung and mediastinum) and conducts research into lung cancer and interstitial lung disease in particular. He reports between 200 and 300 referrals from clinicians and other pathologists, nationally and internationally, each year.

Professor Nicholson lectures regularly at regional, national and international levels. He has spoken extensively in Europe, Asia, North and South America, and Australia, both as a guest speaker at international conferences and as a stand-alone teacher at specific lung pathology courses. He also organises a practical lung pathology course each year, which attracts attendees from around the globe.

He is the former chair of the International Association for the Study of Lung Cancer (IASLC) committee for the classification of lung tumours, as well as a member of the IASLC Staging and Prognostic Factors Committee.
