Jean de Dieu Nyandwi
I am a visiting researcher at CMU's Language Technologies Institute (NeuLab), working with Prof. Graham Neubig and collaborators across CMU. I have also had the privilege of collaborating with Prof. Deva Ramanan. I work on machine learning and multimodal AI, with a focus on understanding when and why models fail and developing methods to diagnose and mitigate these failures. I hold an MS in Engineering AI from Carnegie Mellon University.
