I have a background in mechanical engineering. I received my degree in computational science of crystal growth and studied AI/information science and technology during my post-doctoral years. Through activities to incorporate AI into crystal growth science, I will accelerate the development of next-generation semiconductors and contribute to energy conservation and reduction of CO₂ emissions.
