But this was not *her* first joint degree; she also holds a BA in Mathematics and Linguistics from UChicago. She was most recently a postdoc at NYU, where among other things she collaborated with Tal Linzen on a project showing that statistically trained language models like BERT form representations of morphosyntactic features during training.
Rafael Hernández, Lecturer of English, considers modernism’s interest in embodiment—notably, how modernism envisioned the body as under regular threat of disease, disability, gender flux, and racial slippage. Throughout his work, Hernández locates the medical and quasi-medical origins undergirding long-form narratives about health and disability in the early twentieth century. Nineteenth century socio-medical discourses rapidly reached a fever pitch of paranoia in the moment of early modernism and newly framed the body as the site of social and moral deviance, from disease and disability to miscegenation and gender play. In his research, he traces this story as rendered in the literature and popular discourse of the time to show how the political, social, and cultural instability of the modernist moment was attached to disruptions in bodies along with their representations in art and literature. Alongside his research, Hernández teach courses in British and Irish modernism, nineteenth- and twentieth-century Anglophone literature, and special topics courses on disability studies and the works of James Joyce.
Arianna Q. James, Assistant Professor of English, also has affiliations in the African American & Black Diaspora Studies Program and the Cinema and Media Studies Program in the College of Arts & Sciences. Professor James specializes in African American and Asian American literature and film studies. Her book project, A Sense of AfroAsia: Blackness, Asianness, and the Speculative, collapses the boundaries between African American and Asian American literature and theory to experiment in the expansive field of Afro-Asian studies. Invested in ways of reading and being beyond institutionalized field delineation, A Sense of AfroAsia argues that aesthetic markers of AfroAsia beyond bodily encounters speak to a long tradition of crossing and speculative race-making in the U.S. Outside of her primary fields of study, Arianna’s other research and teaching interests include media and fan work, speculative fiction, and digital humanities, as well as constellating theories around queerness, mixedness, and the body.
Daniel Munro, Assistant Professor of Philosophy, has main interests in epistemology, philosophy of mind, and philosophy of cognitive science. Much of his research is about the imagination. In addition to foundational questions about the imagination’s nature and epistemic value, he’s interested in how theorizing about the imagination can help us better understand domains such as conspiracy theorizing, religious cognition, and artificial intelligence. Daniel received his PhD from the University of Toronto and his BA from the University of British Columbia. Before coming to BU, he held a postdoctoral fellowship at York University.
Miguel Ohnesorge, Assistant Professor of Philosophy, is a philosopher and historian of science.

Apekshya Prasai, Assistant Professor of Political Science, researches the relationship between gender, conflict and social transformation, with a regional focus on South Asia, especially Nepal. Her book project examines the gendered ways in which insurgents organize violence and explains why some rebels conform to patriarchal norms while others radically subvert them. Presenting a novel theory of militant female activism, her work highlights the critical but neglected role women play in shaping the gender strategies rebels adopt. Her book and other related projects draw on extensive data collected through ethnographic fieldwork in Nepal and archival research in the Netherlands and across several digital archives. Combining semi-structured interviews, oral histories and rare primary documents in Nepali, Hindi and English, her research sheds lights on the social, especially, gendered processes of civil wars.

Patrick Sheehan, Assistant Professor of Sociology,
Brianna Tafolla Riviere, Assistant Professor of History,
Chepchirchir Tirop, Assistant Professor of History, is an historian of Africa interested in the social and cultural histories of East Africa. Her previous research focused on the Indian diaspora in Kenya, examining how memory, identity, and nation-building have evolved in post-independence Kenya. Her scholarship has appeared in publications such as Eastern African Literary and Cultural Studies and Africa Is A Country. Her dissertation project examines the political role of athletics in Kenya from 1945 to 2000, arguing that sports were central to decolonization, nation-building, and Cold War diplomacy. She demonstrates how both colonial and postcolonial governments leveraged track and field to advance political agendas—from managing racial hierarchies during decolonization to forging national unity and navigating Cold War politics after independence. Her work reframes African histories by highlighting sport as a site of colonial continuity and postcolonial agency, repositions Kenya as an autonomous Cold War actor, and recovers the often-overlooked role of African athletes in global sports history.
