I’m a postdoctoral researcher in the Department of Computer and Information Science at the University of Pennsylvania. I am grateful to be advised by Dr. Lyle H. Ungar and Dr. Sharath C. Guntuku. I completed Ph.D. from the University of Delhi, India. I build human-centered AI to promote positive behaviors. Currently, I am working on:

• [cultural alignment] Building socially aware AI that aligns with users’ preferred style, emotions and norms
• [behavioral health] Measuring & mitigating demographic bias in AI mental health assessment
• [AI x behavioral health] Building AI systems for promoting healthy behaviors such as vaccine uptake
• [biases x AI safety] Designing framework to measure harmful social biases in digital media - a colab with the World Bank

I am on the faculty and industry job market. I am applying broadly across disciplines, and would be grateful to hear of relevant positions.
