Frederick Sanger's determination of the first complete amino acid sequence of a protein (insulin) in 1955, led a number of researchers to sequence various proteins from different species.

She taught physiology and biophysics for 13 years, while becoming affiliated with the National Biomedical Research Foundation, a Fellow of the American Association for the Advancement of Science, a councillor of the International Society for the Study of the Origins of Life (1980) and acting on the editorial boards of DNA, Journal of Molecular Evolution and Computers in Biology and Medicine.
