Cheryl Xu

Associate Professor

Dr. Chengying “Cheryl” Xu’s research interests are advanced manufacturing of multifunctional materials, sensor design and manufacturing in harsh environments, process optimization, sensor-based health monitoring and control through artificial intelligence (AI). Dr. Xu is active in conducting research in the field of materials processing and advanced manufacturing and has attracted a high level of research funding. She joined in NC State University in 2018. She was an Assistant and Associate Professor at the University of Central Florida (2007-2013) and was an Associate Professor at Florida State University (2014-2018). She co-authored a textbook (Intelligent Systems: Modeling, Optimization and Control, CRC Press, 2008) and have published four book chapters. Dr. Xu chaired the 1st NSF National Wireless Research Collaboration Workshop in 2015 and serves as an Associate Editor of ASME Transactions, Journal of Micro- and Nano- Manufacturing since 2015.

Dr. Xu’s research focus is manufacturing of multifunctional ceramic materials, especially on their electrical/dielectric, mechanical, and thermal properties, and how to manufacture such materials for high temperature applications. Such studies provide great flexibility in design and manufacturing and meet a wide range of application requirements, such as high temperature sensor design, electromagnetic (EM) absorption material, conformable patch antennas, high temperature radio frequency (RF) transparent materials, metamaterial designs for extreme condition applications, etc. The capabilities to effectively integrate these technologies and materials into applicable devices are critical  for industry and the federal government laboratories. Our goal is to become a pre-eminent research group in the field of advanced manufacturing and to apply the knowledge and experience to help bring engineering components and devices for next generation energy, environmental, aerospace and defense applications. Our research interests have been in the field of advanced manufacturing, with specific focuses on the following aspects:

  • Research and development of novel multifunctional materials with desirable structures/functionalities;
  • Developing practical/robust manufacturing processes to transform new materials into engineering components and devices;
  • Understanding the fundamental physics and chemistry of advanced manufacturing processes;
  • Integrating artificial intelligence / machine learning into manufacturing processes.
