It was real pleasure to stay at Ishihara lab to spend my Ph.D. life which was 3 years. I started my topic with a few knowledge backgrounds but fortunately, I got successful graduation in 3 years. During Ph.D. course, I had many opportunities to grow up, receiving high-quality guidance and reasonable training from Ishihara sensei. In addition, Ishihara Sensei and the rest of the staffs are always kind and supportive, creating a comfortable work environment for students. So, if you are intensely determined to pursue scientific research, Ishihara lab would be your top choice.
