Dr. Masaki Koh has successfully graduated from Graduate School of Medicine and Pharmaceutical Science, University of Toyama today. In Japan, March is the month of graduation. He has carried out three experiments on stem cell, malignant lymphoma, and malignant glioma and several clinical researches such as Toyama Stroke Registry (TOY STORE study) for these 4 years. I am sure that he will be an excellent neurosurgeon with the mind of neuroscientist in very near future. Boys and girls, be ambitious!
