Switching gears in his late teens, Soren received a B.A. in Greek and Roman Studies from
Dartmouth College, then an M.A. in Fine Arts and a Ph.D. in Classical Archaeology from
Harvard University. During this time he directed archaeological investigations for the
Smithsonian Institution at
Utica,
Thuburbo Majus and
El Djem in Tunisia. He taught at the
University of Missouri in
Columbia, Missouri for 10 years from 1973, becoming department head in the Art History Department and directing excavations at
Miróbriga, Portugal, where he co-designed a large room of the
Santiago do Cacem Museum with
Star Wars production designer
Harry Lange. He was also Guest Curator at the American Museum of Natural History in New York City from 1980 to 1988. Soren moved to the
University of Arizona in 1983, first as department head in Classical Studies, later being appointed Regents Professor of Classics and Anthropology. Soren is known in archaeology primarily for three discoveries. His archaeological excavations at
Kourion, Cyprus were designed to identify the epicenter of the famous Mediterranean
earthquake of July 21, 365 A.D. He located the epicenter of this mega-disaster offshore approximately 25 miles southwest of the town of Kourion.
Brian Fagan described this discovery as one of the 50 most significant in world archaeology. His second discovery was the identification of
Plasmodium falciparum malaria as a significant contributor to the
downfall of the Roman Empire. This was done through analysis of DNA of infant bones from a cemetery he excavated at
Lugnano in Teverina, Umbria between 1987 and 1991 – the first such use of DNA evidence on an archaeological site. The third discovery was the site of the famous Roman
fontes Clusini or Springs of
Chiusi, a healing sanctuary featuring a cold water spring said by the poet
Horace in his
Epistles to have cured the gravely ill
emperor Augustus from his stomach pains in 23 B.C. Soren discovered the largest cold water ancient spring and sanctuary in Italy, near
Chiusi in the Tuscan town of
Chianciano Terme. The ancient spring he found was still flowing and the water contained large amounts of calcium sulfate which functions as a strong laxative. He has also staged museum exhibitions for the American Museum of Natural History and the
Hayden Planetarium. == Biographical writings and cinematic work ==
