He has performed exercise tests with focus on laryngeal function at stress for more than fifteen years and has been leader of the ELS Committee on EILO since 2012 ( 

He has published more than fifty original scientific papers in addition book chapters and reviews. He has contributed with numerous scientific presentations at international and national conferences.


Tod Olin

Associated Professor Tod Olin, is a pediatric pulmonologist and director of the Exercise and Performance Breathing Center at National Jewish Health in Denver, Colorado, USA. He is specifically interested in helping children and adults exercise safely and comfortably across the spectra of health and performance.

He has invented two novel therapies for exercise-induced laryngeal obstruction, a condition for which Dr. Olin is considered a field leader. Dr. Olin also values working with sporting bodies to inspire and promote population health, serving as a respiratory consultant for USA Swimming.


Camilla Slot Mehlum

Camilla Slot Mehlum MD/PhD is a consultant oto-rhino-laryngologist at the Department of ORL-Head & Neck Surgery, Odense University Hospital in Denmark.

She has more than ten years of experience in diagnostics and treatment in the field of laryngology, including diagnosis and surgical treatment of EILO.

She is chairman of the Danish Laryngological Society and part of the European Laryngological Society Committee on EILO.


Emil Walsted

Dr Emil Walsted PhD is a respiratory registrar at Bispebjerg Hospital in Copenhagen, Denmark. His research interests focus on EILO and include unexplained exertional breathlessness, cough and the overlap between asthma and laryngeal obstruction.

Dr Walsted aspires to progress diagnostic methods and treatment by advancing the understanding of pathophysiology in laryngeal dysfunction. Making use of on his previous background in computer science, he enthusiastically employs new technology and advanced computational methods in this endeavour.

Tiina Andersen

Dr Tiina Andersen is a Specialist in Respiratory Physiotherapy, PhD. She is working as physiotherapist and postdoctoral researcher at Norwegian Advisory Unit for Home Mechanical Ventilation, Thoracic Department, Haukeland University Hospital, Bergen, Norway, and as Associate Professor at the Faculty of Health and Social Sciences, Western Norway University of Applied Sciences, Bergen, Norway.

Andersen has more than 10 years of experience using Transnasal Fiberoptic Laryngoscopy (TFL) during mechanically assisted cough and ventilation.  Her research has demonstrated that non-invasive respiratory therapies can provoke adverse laryngeal responses in patients with motor neuron disorders like Amyotrophic Lateral Sclerosis (ALS), and that therapy can be improved by modifications.


Tom Karlsen

Tom Karlsen is a Speech Therapist/Phd, working with ILO at Stemmelogopedi AS, Bergen, Norway and at the Department of Pediatrics at Haukeland University Hospital, Bergen, Norway.

His education as a speech therapist in the late 1990s came as a result of his interest in breathing and voice, and for more than two decades he has specialized in this field.
