Sacks earned a MA from Princeton, and a BA summa cum laude, Phi Beta Kappa from Tufts University, both in history. A research affiliate of the Harvard-Cambridge Joint Center for History and Economics, he previously held Princeton's inaugural Digital Humanities Fellowship (2015-16), and The Huntington Library's Michael J. Connell Foundation Fellowship (2014). He is the recipient of a number of honors, including the Tufts Institute for Global Leadership's Alfred Rubin Colloquium Award (2017), the Society for American City & Regional Planning History's Auguste de Montequin Prize for North American history (2013), and the Beinecke national scholarship for graduate studies (2009). In 2012, he became one of the youngest individuals ever elected to the fellowship of the Royal Geographical Society. He routinely gives invited lectures in Europe and North America on colonial urban history, historical and contemporary US and British soft power relations, the history of cartography, and geography's role in history, grand strategy, and international affairs.
In 2017-2018, Sacks will hold a Princeton Institute for International and Regional Studies (PIIRS) dissertation completion fellowship. In October 2017, he will give two invited talks on colonial cities, historical cartography, and digital humanities at Stanford University's David Rumsey Map Library.
