Head of School, Philosophy Core & Mathematics Instructor
Originally from Japan, Dr. Hoshi earned his B.A. in Philosophy from the University of Tokyo, M.A. in Philosophy at Texas A&M, and Ph.D. in Philosophy at Stanford University. After teaching courses on logic and philosophy at a number of places, including Stanford University, he joined the Online High School. He is excited to serve the school as the Director of Stanford Online High School this year. He will still continue to teach a class for History and Philosophy of Science (OHSC0).
In addition to teaching, Dr. Hoshi has engaged in various research projects on logic and has published papers in related fields, including philosophy, computer science, and mathematics.
Dr. Hoshi also loves cooking. In Tokyo, he worked as a cook for four years. His favorite foods are Italian, Korean, and Japanese. He also is a part of the Stanford Japanese Running Club and has been training for his third marathon this year.
