Today, we’re profiling Serafin Diaz, vice president of engineering at Qualcomm Technologies. Diaz grew up in La Paz, Baja, Mexico where he developed an early fascination of electronics and how things work. He’s put that inquisitive nature to good use in his almost-20 years with the company, working on a variety of projects, from designing and executing test cases for cellular systems to field testing EV-DO to starting and leading R&D in augmented reality (AR) and computer vision.
