About Me

I am a Computer Science PhD candidate at Stanford University working with Zakir Durumeric in the Empirical Security Research Group (ESRG). My research interests are broadly at the intersection of security, human-computer interaction, and policy. I'm currently working on better understanding and developing tools to mitigate various flavors of online abuse, like misinformation and hate and harassment. Previously, I graduated from UC Berkeley (B.A. '20), where I worked with Serge Egelman at the Berkeley Lab for Usable and Experimental Security (BLUES).
