Daniel Nkemelu

I am a PhD student in Human-Centred Computing at Georgia Institute of Technology, advised by Mike Best and Irfan Essa. My research interests are in Machine Learning for Development, Human-Computer Interaction, and Computational Social Science.

My research aims to advance our understanding of and develop tools to tackle digital threats to democracy and political participation within developing, under-resourced contexts. I'm interested in the positives (how people use technology to mobilize, organize, and protest), and the not positives (understanding the spread of hate speech, d(m)isinformation, and online incitement); I build AI-driven tools to address these issues.

Prior to beginning my Ph.D at Georgia Tech in 2019, I received a M.S. in Electrical and Computer Engineering from Carnegie Mellon University, and a B.S. in Computer Science from the University of Ibadan.
