My research is centered on the idea of 'voice', which I define as an instrumental and constitutive means of development. My research is deeply concerned of the issues related to sustainability and social justice, and I am critical to the modernist, neoliberal, and capitalist approaches to those issues. Most of my research focuses on studying, analyzing, and designing computing technologies with marginalized populations around the world through this lens. I draw heavily on political philosophy, critical theory, social science, anthropology, and STS literature in my work. I design, develop, deploy, and evaluate technologies that connect theories from these disciplines to mobile and ubiquitous computing, natural language processing, social media, and machine learning. My research involves both theoretical depth and technical challenges.
