Joshua's research focuses on 19th century British entrepreneur-collectors, who used contemporary art for financial investments. This work is inter-disciplinary, combining subjects such as collecting, taste, class as well as financial speculation and is intended to trace the increasingly commoditized nature of art in the United Kingdom.
Before starting his PhD, Joshua worked from 2015 to 2018 at George Mason's Gunston Hall, a house museum in Virginia and performed ongoing research about the 18th century, including the politics, economics and art in order to provide accurate, wide-ranging and interesting information for tours. Along with his responsibilities as guide, he worked as a Curatorial Associate and carried out research to support Gunston Hall’s curatorial needs. As part of his work, he assisted the Curator of Collections in creating an installation about classicism in American architecture, linking design codified by Andrea Palladio to architectural fragments recovered from Gunston Hall’s interior.
From 2017 to 2018, Joshua also worked as a Lead Gallery Guide at the Hirshhorn Museum & Sculpture Garden, in Washington, DC, where he managed and assisted other guides as well as gave tours about modern and contemporary art. He holds a BA in English with minors in Art History and History (2012), as well as a MA in History (2016), both from George Mason University.
