Dr. Youngblood is an Assistant Professor in the Electrical and Computer Engineering Department at the University of Pittsburgh. He received his PhD in electrical engineering from the University of Minnesota.
His research at the University of Minnesota focused on integrating 2D materials with silicon photonics for high-speed optoelectronic applications. From 2017 to 2019, he worked as a postdoctoral researcher at the University of Oxford developing phase-change photonic devices for integrated optical memory and computation. His research interests include bi-stable optical materials, 2D material optoelectronics, and photonic architectures for machine learning.
