As Chair of ITU-R Study Group 3, he played a guiding role in shaping the study and application of radio-wave propagation in the ionized and non-ionized atmosphere. His leadership was instrumental in the development and revision of numerous ITU-R P-series recommendations that contributed to the improvement of radiocommunication systems worldwide. <a
