Armed with shovels, trowels and new biotechnology tools, archaeologists plan to march into Troy next year for excavations at the famed ancient city.”Our goal is to add a new layer of information to what we already know about Troy,” said William Aylward, a classics professor at the University of Wisconsin-Madison, who will lead the expedition. “The archaeological record is rich. If we take a closer look with new scientific tools for study of ancient biological and cultural environments, there is much to be found for telling the story of this world heritage site.”
