Ji Su Yoo

I'm passionate about building inclusivity and safety into the very design of products that shape our everyday lives. I'm a Product Manager and Co-founder of PlatformAbuse.org -- a knowledge source of technological harms and mitigations, which won prizes in the UC Berkeley Big Ideas Contest and the Mozilla Builders Open and MVP Lab. I also developed the Abusability Testing Framework that provides systematic guidelines for human-centered, user-centered, and ethical design. 

I'm also a PhD student at the UC Berkeley School of Information, where I focus on the intersection of technology and inequality and social computing using mixed methods. I was the co-director of the Center for Technology, Society & Policy; the first Ph.D. student representative for I School Diversity, Equity, Inclusion, & Belonging; and a Paul and Daisy Soros Fellowship recipient. Previously, I was a researcher at the Harvard Institute for Quantitative Social Science and Data Privacy Lab. 

I'm interested in trust and safety, tech equity, mitigating platform abuse, and tackling digital harms.
