• My interdisciplinary research and teaching focus on legal borders, human mobility, and social inequalities.  Specifically, I analyze interaction across urban politics, civil society actors, and policy institutions concerning migration governance and social inequalities in cities in global comparative perspective. In particular, I am interested in how urban law and politics intersect with international and national institutions to shape migration policies and practices, and how these governance processes are embedded in broader histories and dynamics of social and spatial borders in cities.

    My research has been funded by various grants including US Fulbright Student and Fulbright-Hays Doctoral Dissertation Research Abroad (DDRA) fellowships and published in Racial and Ethnic Studies, Journal of Ethnic and Migration Studies, and Journal of Immigrant and Refugee Studies.

    Previously, I was a Lecturer in the Department of Sociology at the University of Vermont (UVM) and in Urban Studies at Yale-NUS, Singapore. Additionally, I was a Joint Postdoctoral Fellow, Department of Sociology, University of Toronto, and the Max Planck Institute for the Study of Religious and Ethnic Diversity (MPI-MMG), Germany. I have been a Visiting Research Fellow with the Urban School at Sciences Po, Paris, the Scalabrini Institute for Human Migration in Africa (SIHMA), Cape Town, and a fellow with the Academy for African Urban Diversity (AAUD).

    I received my PhD from the Department of Sociology at the University of California, Los Angeles (UCLA). I hold an MA in Sociology from UCLA; MA by Research in Forced Migration Studies from the African Centre for Migration & Society (ACMS), University of the Witwatersrand; MSc in Global Politics from the London School of Economics and Political Science (LSE); and a BA in Peace & Conflict Studies from the University of California, Berkeley.
