Kyoshiro Hiki

Dr. Kyoshiro Hiki is a lecturer at the University of Tokyo. He received his PhD from the University of Tokyo in 2016 and subsequently worked at the National Institute for Environmental Studies as a postdoctoral fellow and senior researcher. His research interests include ecotoxicology and ecological risk assessment, with a focus on sediment contamination, urban runoff, and the application of molecular technologies. Following his master’s work, he has evaluated the toxicity of road dust and road runoff-related chemicals on aquatic and benthic organisms. Since the discovery of 6PPD-quinone as the causative agent for acute die-offs of coho salmon, he has further investigated the toxicity of 6PPD, 6PPD-quinone, and related chemicals to aquatic organisms, while also pursuing the underlying mechanisms of 6PPD-quinone toxicity.
