After joining Murata in 1988, Shigeyuki Mikami was involved in design and sales engineering for dielectric resonators. Following this experience, he worked on the development of millimeter-wave filters and modules. He was then transferred to the sales department, where he was responsible for marketing related to mobile communications until being appointed to his current position in 2008. Mikami's favorite pastime is the theater. As his motto he always reminds himself that “what one is today, for good or bad, represents the effects of what one did in the past.”
