BioMed Alliance is deeply saddened by the passing of Prof. Tobias Welte on 10 March, at the age of 64. Tobias Welte was a valued member of our Board of Directors and was Treasurer until 2023. He was a high-level expert in the field of respiratory medicine, and made numerous contributions during the COVID-Pandemic and to his field in general. Our thoughts are with his family and friends during this difficult period.
