Haru is a Project Lecturer and Principal Investigator at the Institute for Advanced Life Sciences, Keio University, Japan. He received his PhD in Agriculture from Tokyo University of Agriculture and Technology (TUAT). After being a postdoctoral researcher at Tokyo Metropolitan University and TUAT, he moved to Scotland to join the laboratory of Professor Angus Lamond at the University of Dundee, where he developed a method for characterizing large cellular protein complexes, such as ribosomes in mammalian cells, using size-exclusion chromatography combined with mass-spectrometry-based proteomics. His current research focuses on changes in ribosomes and their synthesis in the nucleolus under various stress conditions in mammalian cells.
