Go Maruyama becomes pSemi’s CEO as Tatsuo Bizen retires
Murata company pSemi Corp of San Diego, CA, USA – a fabless provider of radio-frequency (RF), analog and mixed-signal solutions – has announced leadership changes and organizational restructuring to support its evolving business strategy and future growth.
After a 40-year career, Tatsuo Bizen has retired as CEO of pSemi and vice president of Murata Manufacturing Company Ltd’s (MMC) power modules division, but continues in a corporate advisor role at MMC.
Since joining Murata in 1985 as an RF engineer, Bizen has held leadership positions across its global operations, including product management in Europe, head of corporate global marketing, and in CEO roles at acquired companies SyChip, Murata Power Solutions, and pSemi. His leadership has played a crucial role in stabilizing and strengthening businesses across multiple regions and product areas, comments the firm.
Go Maruyama has assumed the role of CEO of pSemi, after nearly three decades of experience within Murata and its subsidiaries. He began his career in corporate planning and has held positions in marketing, business development, and product management in both Japan and China. Since joining pSemi in 2017, he has played a key role in corporate strategy and post-merger integration. In his new role, he will lead pSemi into its next phase of collaboration with Murata and its affiliates.
“My focus will be on fostering a culture of collaboration between Murata and pSemi, increasing our agility, and striving for continuous growth as we expand our impact in the semiconductor industry,” says Maruyama.
To support pSemi’s evolving business strategy, the firm also announced several key leadership promotions:
- Keith Bargroff has been promoted to senior VP, engineering and technology;
- Joel Keller has been promoted to senior VP, administration;
- Taro Desaki has been promoted to VP, corporate planning and business operations.
The promotions align with pSemi’s commitment to strengthen administrative functions, accelerate R&D, and enhance RFFE (radio-frequency front-end) and power management IC technology competitiveness through closer collaboration with Murata companies and other affiliates, including Eta Wireless.
