Ayano Hiranaka

I recently completed my Master's degree at Stanford University. At Stanford, I was a research assistant at Stanford Vision and Learning Lab (SVL) working with Prof. Fei-Fei Li , Prof. Jiajun Wu, and Dr. Ruohan Zhang.

Currently, I am working as a research intern at Sony AI.

I received my undergraduate degree in mechanical engineering from the University of Illinois at Urbana-Champaign (UIUC). My experiences are a unique blend of computer science and mechanical engineering, ranging from AI to robotics to mechanical design.

I am actively looking for PhD positions for fall 2024.

I am passionate about designing robots that can be incorporated into everyday life as human companions. My research interest lies in developing methods that enable robots to communicate effectively and collaborate seamlessly with humans in households or public spaces, increasing the quality of human lives , while evolving alongside humans by learning from them. Topics of interest include human-in-the-loop learning, interactive human-robot collaboration, reinforcement learning, and imitation learning, especially for robotics applications.
