On his retirement from the University of Hong Kong in 1989, John joined the University of Virginia as Professor and Chairman of Division of Statistics. In 1995 he received the William Christian Krumbein Medal of the International Association for Mathematical Geology for a 'distinguished career as author and researcher in the field of mathematical geology.'
