Zach completed his Ph.D. in Geoarchaeology under the supervision of Prof. Israel Finkelstein of Tel Aviv University and Prof. Ruth Shahack-Gross of the University of Haifa. His dissertation focused on the Intermediate Bronze Age (c. 2500-1950 BCE) settlement phenomena in the arid Negev Highlands through a microarchaeological perspective. Zach received his B.A. in Archaeology and Classics at George Washington University in Washington, DC, followed by an M.A. in Archaeology of Ancient Israel at Tel Aviv University.
Zach has excavated extensively in Israel, including Megiddo (2008, 2012-present), Tel Kabri (2009, 2013), Kirath-Jearim (2017), and for his PhD has led geoarchaeological investigations at a number of Early Bronze (c. 3600-2500 BCE) and Intermediate Bronze Age (c. 2500-1950 BCE) sites in the Negev Highlands (2012-present).
