Current Opinion in Allergy and Clinical Immunology was launched in 2001. It is one of a successful series of review journals whose unique format is designed to provide a systematic and critical assessment of the literature as presented in the many primary journals. The fields of allergy and clinical immunology are divided into 14 sections that are reviewed once a year. Each section is assigned a Section Editor, a leading authority in the area, who identifies the most important topics at that time. Here we are pleased to introduce the Journal's Editors and Section Editors for this issue. EDITORS Giorgio W. CanonicaGiorgio W. CanonicaProf. Giorgio W. Canonica is Professor at Humanitas University, Italy, and Director of the Personalized Medicine Clinic: Asthma and Allergy at the Humanitas Clinical Research Center, Milano, Italy. He was formerly Director of the Allergy and Respiratory Diseases Clinic, Genoa University, Italy; a GALEN Centre of Excellence. Professor Canonica first specialised in pulmonary diseases after having received his medical degree from the University of Genoa, Italy. He then specialised in allergy and clinical immunology at Florence University, Italy. He subsequently conducted clinical immunology and allergology research in several European universities and institutes, in addition to two years at the Medical University of South Carolina, USA.

Professor Canonica's research interests include examination of the molecular events and interactions between immunocompetent cells, inflammatory cells and epithelial cells in allergic inflammation and airway remodelling. He is particularly involved in new strategies in the treatment of allergic disease, including biological response modifiers, such as specific immunotherapy (with a special focus on SLIT – sublingual immunotherapy) and biologics. Professor Canonica has published extensively in international journals and acts as a referee of many immunology journals. In addition, Professor Canonica is a member of a number of societies, and recently served six years as Secretary General and President Elect of the World Allergy Organisation (WAO), and was President of WAO 2008–2009 and President of Interasma 2015–2016.

Dr Skoner co-founded the Nemacolin Asthma Conference (www.ahn.org/nemacolin-asthma), a CME program that attracts an international audience and faculty, now in its eleventh year. Dr Skoner also founded two non-profit organizations, For Your Good Health (www.fygh.org) and Maci's TEAMS (www.macisteams.org), designed to keep children with allergy and asthma “active” and “safe on medications”, respectively. These non-profits bring together asthma stakeholders in the development and implementation of state-of the-art programs to educate children with asthma and their caregivers about the disease and its management, including medication safety. The aim of these programs is to reduce asthma's impact on patients, caregivers, the community, and the healthcare system by helping the patients to lead near-normal lives and be free of medication side effects. He also previously served on the board of the non-profit Greater Pittsburgh Allergy Asthma and Immunology Society (GPAAIS), which serves to educate and inform physicians and other health care providers.
