Brian Leibowitz, PhD

Brian S. Leibowitz is an analog mixed-signal circuit designer at Apple, where he works on the integrated circuit technologies underlying the company’s hardware products. Leibowitz earned his undergraduate degree at Columbia University before completing his doctorate in electrical engineering at the University of California, Berkeley, where his Hertz Fellowship supported research on CMOS imaging receivers for free-space optical communication — systems that use modulated light beams rather than fiber or radio waves to transmit data. That work, at the intersection of optoelectronics and high-speed circuit design, laid a foundation for a career in analog and mixed-signal integrated circuit engineering at one of the world’s leading semiconductor design companies.
