Dvorak is an associate professor of International Cultural Studies at Waseda University in Tokyo, where he is based in both the Graduate School of International Culture and Communication Studies (GSICCS) and the School of International Liberal Studies (SILS). He completed his MA at the University of Hawai'i (2002) and his PhD at the Australian National University (2008), with a concentration in Pacific Islands History. His research focuses mainly on themes of militarization, memory, gender, sexuality, and art between Oceania (particularly the Marshall Islands), Japan, and the United States. He is the founder of Trans-oceania, a program to foster international Pacific Studies in Japan. As an offshoot of this, he also began Project35, a small network of artists, activists, and scholars that collaborate on themes of demilitarization, decolonization, and environment through the promotion of contemporary Pacific art. His cultural history of Kwajalein Atoll, Concrete and Coral: Remembering Kwajalein Atoll between Japan, America, and the Marshall Islands, was published from University of Hawaii Press in 2018.
