I am pleased to announce that Kotaro Hara passed his PhD defense this afternoon on "Scalable Methods to Collect and Visualize Sidewalk Accessibility Data for People with Mobility Impairments." It was a true pleasure advising Kotaro, my first PhD student. I will miss his generous spirit, creativity, and his passion for research with a social impact. This fall, Kotaro joins CMU as a post-doc with Jeff Bigham and Aaron Steinfeld.
