Faisal Husain is a historian of the early modern Ottoman Empire (c. 1450-1800), with a focus on the Ottoman provinces of southeastern Anatolia and Iraq and their natural environment. His current book project, Water and Power in the Ottoman Tigris-Euphrates Basin, examines the establishment of a unified imperial regime over the Tigris and Euphrates in the sixteenth century and the consequences of this political transition on the Ottoman state, provincial settlements, and the environment. Husain has a background in historical climatology. In two workshops at Princeton University in 2015 and 2016, he learned to work with the evidence trees and pollen grains provide for historical climate variability. He currently serves on the editorial board of Global Environment.
