Mimo Shirasaka Hi! I am a master's student in the Computer Vision Group at The University of Tokyo, advised by Prof. Yoichi Sato. I am also a research engineer intern at AIRoA. I received my bachelor's degree in engineering from UTokyo in March 2026, where I was advised by Prof. Jun Ota. During my undergraduate studies, I interned at the Tokyo Robotics and AI Lab (TRAIL) as a research assistant, advised by Dr. Tatsuya Matsushima. I also interned at OMRON SINIC X as a researcher and at Mercari as an ML engineer. I am working closely with Prof. Yonatan Bisk at Carnegie Mellon University. Before joining UTokyo, I worked with Prof. Norihiko Sugimoto on the atmosphere of Venus as a high school research scholar in the JST Global Science Campus Program. |

Mimo Shirasaka, Haochen Zhang, and Yonatan Bisk EMNLP Findings, 2026 Website / Code / Dataset POVBench evaluates contextual observer grounding: recovering a speaker's viewpoint from contextual cues and localizing an object they described from that viewpoint. State-of-the-art VLMs struggle, and explicitly decomposing the reasoning improves localization. |
