About me

I'm a Ph.D. student at the Human-Computer Interaction Institute at Carnegie Mellon University, advised by Prof. Jason Hong. My main research interest focuses on helping developers make privacy-friendly apps. I am particularly interested in understanding why people create apps that violate privacy and building tools for developers to make protecting user's privacy a simple and straightforward task. I also work on side projects about notifications and mobile text entry.
