Riyad Bin Rafiq is a PhD student at the University of North Texas as part of the Biomedical Artificial Intelligence lab. His previous work has been in sign language recognition models for communication, and his current research interests are in developing more general gesture recognition models for patients with a limited ability to communicate verbally. A key aspect of success is in developing accurate classification models not only for laboratory conditions, but also in real-world scenarios, supporting his interests in proper model validation. He previously graduated from Chittagong University of Engineering and Technology, Bangladesh.
