About me

I am a fourth-year Ph.D. student in Computer Science at the University of Maryland, College Park, and a member of Human-Computer Interaction Lab and Intelligent Assistant Machines Lab, advised by Hernisa Kacorri.

My research on Teachable Interfaces through Human-Centered Artificial Intelligence focuses on enhancing AI by involving humans in the loop and building AI-powered systems to empower people with and without disabilities, which combines methods from machine learning and human-computer interaction.

I am interested in exploring human interactions with AI to design an AI-powered system that can understand the user's intent. My current project is to design a Teachable Object Recognizer for blind people using sonigifcation, haptic feedback, and deep learning models.
