A Quick Bio

I am a fifth-year Ph.D student at the University of California, Irvine working in applied cryptography under Gene Tsudik.
My current research deals with Usable Security, particularly the prevalence of user errors in the presence of adversarial noise across multiple sensory inputs. I am also developing a technique for passive deauthentication based on biometric data. In the long term, I am interested in the development and evaluation of usable security protocols for Internet of Things (IoT) devices. In the past I have worked on the development and deployment of an accessible, coercion resistant voting machine.
