Abhiraj Kesharwani is a Postdoctoral Researcher at the University of Tokyo, where he focuses on developing vascularized bone organoids using human pluripotent stem cells and organ-on-a-chip systems to model bone development and diseases. He completed his Ph.D. in Bioengineering at the University of Tokyo in March 2025, supported by the JICA FRIENDSHIP Scholarship. His doctoral research involved studying bone-vascular interactions and tissue development using a microfluidic chip to investigate vascularized bone organoids. With a background in bioengineering, pharmacy, and bioinformatics, Abhiraj aims to bridge stem cell biology and microengineering to advance human disease modeling and translational research.
