Warrick Moses (Postdoctoral Fellow) received his PhD in African and African American Studies with a secondary field in Ethnomusicology from Harvard University in May 2019. His dissertation project, In the Mix, explores expressions of “mixed race” or “coloured” socio-political, linguistic, and cultural identity in Cape Town-based hip hop music.

Warrick’s academic interests include Afrofuturism from the continent; performativity and/of Blackness; Diasporic musical praxis; and applied ethnomusicology. Warrick also holds a Master of Woodwind Performance degree from Boston University, and a Master of Arts degree (Ethnomusicology) from Tufts University. 





Jason Ng (Postdoctoral Fellow) is a graduate of Monash University in Melbourne Australia. He has diverse experience in Man standing against a white wall researching and teaching communications, globalization, media studies and cultural studies in Australia and across Asia. His PhD research examines contemporary hip hop exchanges facilitated by passionate community leaders framed as cross-cultural intermediaries. These cultural agents work at the intersection of local hip hop forms and international flows of content and communications (around dance, music and the broader cultural ethos) through cultural entrepreneurship, social activism and working with corporate and governmental bodies to create sustainable businesses, events and work for creatives in the Asia-Pacific region.

Through ethnographic case studies across five global cities (Incorporating Tokyo, Bangkok, Shanghai, Melbourne and Singapore) Jason’s thesis provides a cross-national comparative lens to examine the influence of these figures and their work in facilitating local and regional connectivity and belonging. In addition to his PhD research, Jason also has an extensive knowledge of the field from his own critical practice as an artist (through dance, film, music, theatre and event management) and long-term participation in hip hop culture.


Maria FitzGerald Houlihan (Research Support Officer) has a First Class Honours Degree in English and Geography from University College Cork and was UCC College Scholar in 2017. Maria has an established interest in African American literature and postcolonial studies. Her research interests are in Ecocriticism and Nature Writing particularly the eco-critical turn in Irish women’s poetry.  Maria has worked with the European Commission in Brussels and international education.
