Rafal Kocielnik

I am a Postdoctoral Researcher at Caltech where I am mentored by Anima Anandkumar, Mike Alvarez, and Andrew Hung. I received my PhD in Human Centered Design & Engineering from the University of Washington, where I was advised by Gary Hsieh.

My primary interests focus on Leveraging AI for Behavior Change as well as Empowering Users to Inspect AI Systems. I have unique experience in Human-Computer Interaction and Design in combination with Applied ML. I worked on projects in various areas including Explainable AI, Surgical AI, Health Behavior Change, Workspace Productivity and Social Media Moderation.

Over the summers, I've been lucky to intern with Jonathan Bragg and Doug Downey at Allen Institute for AI, Saleema Amershi and Andrés Monroy-Hernández at Microsoft Research Redmond, and Daniel Avrahami at Fuji-Xerox Palo Alto Research Lab.
