Professor Weiss’ research interests include prehistoric and ancient Mesopotamia and Iran, early agriculture, cities and empires; Holocene paleoclimatology and environmental change. Additionally, Professor Weiss has been the Director since 1978 of the Tell Leilan Project (www.leilan.yale.edu), which has redefined the relationships between dynamic natural and social forces in the third millennium B.C. through excavation, GPS/GIS-implemented regional survey and paleoclimatology investigations at one of the largest archaeological sites in Syria. The project is now engaged in the retrieval and analysis of the Akkadian Palace, and its collapse (2200 BC), at Tell Leilan. Yale Tell Leilan Research volumes 3 and 4 are in preparation.
