Senior🎓
Top SchoolTodd Zhang is a Senior Software Engineer and PhD in computer science with 11 years of experience applying machine learning, computer vision, and real-time graphics to production AR/VR products. He specialized in 3D dynamic facial expression analysis—covering detection, registration, tracking, and Facial Action Unit–based classification—and translated that research into native mobile rendering engines as the sole vision/graphics engineer at an AR startup. At A9/Amazon he combines graphics, vision, and ML to build consumer-facing systems from prototype to scale, and he has deep practical experience with Unity and mobile-native rendering pipelines. Known for bridging academic rigor with pragmatic engineering, he has collaborated with artists and led small teams to optimize 3D content for constrained devices. Based in Sunnyvale, he brings both research-first insight and hands-on implementation skills to products that rely on real-time perception and rendering.
