Dr. Eusebio “Bong” Dizon championed Philippine archaeology and its wider regional significance and impact in the interpretation of Southeast Asian prehistory through his interdisciplinary approach and his international collaborations. Paying tribute to the legacy of Bong and his commitment to rigorous science and field methods, we invite scholars to present primary datasets, empirical studies, methodological innovations and new and ongoing excavation results from the prehistory of Mainland and Island Southeast Asia. Topics that cross disciplinary boundaries are welcome, especially if they throw new light on broad issues.
