Manufacturing Innovation and Neural Interface (MINI) Lab
Lei Chen, Ph.D.
University of Massachusetts Lowell
Welcome to the Manufacturing Innovation and Neural Interface (MINI) Lab!
The MINI Lab conducts experimental and modelling work to generate fundamental understandings of manufacturing processes. The research includes but is not limited to innovative experimental monitoring sensors and methods, physics-based numerical modelling, data-based modelling and analysis, and error source analysis and identification of manufacturing processes. Through collaborations with manufacturing industry, healthcare providers, as well as neuroscientists, we aim to implement our manufacturing expertise into broad applications in both industry and healthcare.
Our research interests could be grouped into three main areas: advanced manufacturing processes, brain-machine interface, and biomedical manufacturing. Please see further details in the Research Page.
If you are interested in joining us, please refer to the Available Positions Page for more information.
For questions regarding our research as well as collaboration requests, please feel free to contact Dr. Lei Chen at Lei_Chen@uml.edu.
