"✨ The future of AI can be kind. ✨"

I am an Applied Scientist at AWS, where I conduct research and train engineers through Amazon's Machine Learning University. I got my PhD as an NSF GRFP Fellow from the University of Washington iSchool, where I received the global Doctoral Dissertation Award for my dissertation The Future of AI Can Be Kind: Strategies for Embedded Ethics in AI Education. I challenged myself to 12 Medium articles for 2026, check out my writing!
