Koji Hosaka, PhD

Special Interests

  • Intracranial Aneurysms
  • Aneurysm and Vascular Repair


Koji Hosaka, PhD, was born in Japan in 1975. He attended Nihon University in Kanagawa, Japan and graduated in 1999. Immediately after graduation, he started graduate school at the same university. During his PhD studies, he focused his research on embryology and the establishment of embryonic stem cells from somatic cell nuclei-transplanted embryos. In 2004, he received his PhD in Agricultural Biology and Biological Sciences. After working in Japan for a year, he came to the University of Florida to work as a post-doctoral associate in Dr. Edward Scott’s regenerative medicine research group. In Dr. Scott’s research laboratory, Dr. Hosaka’s research focus was on the role of bone marrow-derived hematopoietic stem cells in embryological development and the role of bone marrow-derived endothelial progenitor cells in retinal neovascularization and inflammation.

Dr. Hosaka joined Dr. Brian Hoh’s cerebrovascular research group in the Department of Neurosurgery in 2008 for a two-year postdoctoral research appointment. In 2010, Dr. Hosaka remained in Dr. Hoh’s research laboratory as an Assistant Scientist, and has been conducting experiments and supervising students.

Dr. Hosaka’s current research in Dr. Hoh’s research laboratory focuses on intracranial aneurysms including understanding mechanisms of aneurysm formation, aneurysm and vascular repair by bone marrow-derived cell recruitment and creation of bioengineered drug eluting neuro-endovascular devices.
