The major goal of 'Expanding Frontiers in Polypeptide and Protein Structural Research' has been to bring the various avenues for the exploration of protein structures to a single forum. The idea of organizing the symposiwn was conceived by one of the editors, V. Renugopalakrislman, during the 9th International Biophysics Congress satellite symposium at Kibbutz Nof-Ginosar, Israel in 1987.
