Overview

Professor Ouyang develops bio-integrated microsystems to advance precision healthcare as well as fundamental brain research. His work spans wearables and implantable biosensors for continuous molecular monitoring of health to neural probes for spatiotemporal mapping of neural electrophysiology and neurochemical dynamics. Before joining Dartmouth, he was a postdoctoral fellow with Professor John Rogers at the Querrey Simpson Institute for Bioelectronics at Northwestern University. He received his BS in microelectronics from Peking University and both his SM in electrical engineering and computer science and his PhD in electrical engineering from the Massachusetts Institute of Technology (MIT), where he trained under Professor Jongyoon Han.

Research Projects

  • Neural interfaces

    Neural interfaces

    We develop devices that enable multimodal, spatiotemporally resolved recording of neuroelectrophysiology and neurochemical dynamics, synchronized with peripheral physiology and behavioral output in freely behaving animals, providing powerful tools for advancing our understanding of the brain.

  • Bioelectronics for precision healthcare

    Bioelectronics for precision healthcare

    We develop wearable and implantable devices for health monitoring and therapeutic intervention, leveraging diverse sensing modalities, including electrochemical, mechanoacoustic, and optoelectronic sensing, and stimulation modalities such as electrical and pharmacological delivery.

  • MEMS and micro/nanofluidic sensors

    MEMS and micro/nanofluidic sensors

    At the core of novel wearable and implantable devices are cutting-edge sensing technologies that can be integrated with the body. In this project, we study fluid and molecular transport phenomena at the micro- and nanoscale to develop tools for precise biomolecule manipulation, enabling lab-on-a-chip solutions for disease diagnosis.

NIH Research Award

Professor Wei Ouyang was awarded a Maximizing Investigators’ Research Award (MIRA) from the National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health. The award provides $2.2 million over five years to support Ouyang's research on implantable technologies for monitoring internal organ health. His work aims to advance understanding of the pathophysiology underlying post-operative complications and inform the development of safer, more effective interventions.
