Ying-Chen Chen is a Ph.D. graduated from Department of Electrical and Computer Engineering (ECE), The University of Texas at Austin. She was a hardware developer at the IBM and Pathfinding Emerging Memory Engineer at Micron, working on inline functional characterization and modeling. At the University of Texas at Austin, she focuses on the topics on the next generation non-volatile memory application for storage class memory and new computing platform.

Her current research and interests emphasize on the combined experimental and modeling approach on several emerging post-CMOS solid-state devices. [1] Materials manipulation, nanostructure, electrical characterization, and physical modeling for high storage class memory; [2] composite material integrations for crossbar array applications, and flexible electronic devices with embedded sensory systems, [3] neuromorphic computing by using emerging memories for synapse-and neuron-mimic system.

Research Interests
Nanotechnology, Microelectronics, Emerging Memory, Neuromorphic Computing, Semiconductor Physics, MOSFET, 2D materials, ferroelectric, wearable flexible skin-like electronics
