About
A little about my work
I am a computer science researcher passionate about leveraging data-driven approaches to solve complex challenges and generate impactful insights. Currently, I work on a Conversational AI Evaluation Tool at the Centre for Responsible AI (CeRAI), Indian Institute of Technology Madras, designed for systematically evaluating chatbot performance — part of a broader interest in creating practical, inclusive, and secure solutions for human–AI interaction.
My earlier research focused on developing accessible and secure user authentication models for persons with disabilities, drawing on principles of usable security to design systems that are both functional and inclusive. I hold a Ph.D. in Computer Science from Pondicherry University, specializing in Human–Computer Interaction (HCI) and Usable Security.
Beyond this, I maintain a strong interdisciplinary curiosity for emerging domains such as Quantum Computing, Spatial Computing, and Generative AI — constantly exploring innovative ways to harness these technologies for transformative impact in computer science.
