The Society is saddened to hear of the death of Member Professor Ronan (‘Ronnie’) O’Regan on 8 July at the age of 83. After studying medicine at University College Galway, he completed a PhD in physiology in 1969 with Eric Neil at the Middlesex Hospital. He returned in 1971 to a lectureship in the Department of Physiology at University College Dublin where he remained until retirement, pursuing research devoted to elucidating the physiological role of carotid body efferent fibres. Appointed to the Chair of Physiology in 1984, Ronnie served three terms as a popular Dean of the UCD School of Medicine until stepping down in 2000. A Society Member from 1972, Ronan O’Regan served two 4-year terms on the Committee, from 1979 and from 1988. Read his obituary in Physiology News here.
