Seminar Series-Qingshan Wei
April 20 @ 1:30 pm
Join us at our upcoming ASSIST Seminar Series featuring Professor Qingshan Wei from the Department of Chemical and Biomolecular Engineering at NC State University.
Topic: Miniature Imaging and Sensing Devices for Global Health Applications
Imaging and sensing tools are indispensable for scientific discovery and innovation. The field is undergoing a profound transformation. The price and size of image sensors, light sources, and optical components have been significantly reduced. The revolution in smartphones and other consumer digital devices have placed low-cost, high-quality imaging systems in the hands of billions of people. Device fabrication and prototyping is becoming increasingly inexpensive and faster than ever with 3D printing. With these trends, various cost-effective, field-portable, and easy-to- use imaging and sensing tools are emerging. Advanced microscopy and spectroscopy measurements can now be rapidly performed on palm-size or wearable devices. Using such miniature devices, personal health can be monitored in real time and continuous fashion via consumer-level health measurement and diagnostic platforms, especially useful in the developing world where diagnostic technologies are often both limited and expensive. This talk will highlight the recent process of using mobile phone and its imaging sensor chip as new generation microscopy tools for point-of- care (POC) diagnostics and global health applications. Both methodological developments and biomedical applications of these miniature imaging platforms will be discussed.Biography
Dr. Qingshan Wei is an Assistant Professor in the Department of Chemical and Biomolecular Engineering (CBE), a part of cluster hires in Emerging Plant Disease and Global Food Security (EPDGFS), and is a full member of Comparative Medicine Institute (CMI) and Center for Human Health and the Environment (CHHE). Dr. Wei received both B.S. and M.S. degrees in Polymer Materials from Zhejiang University, and obtained his PhD degree in Chemistry from Purdue University in 2012. He was a postdoctoral scholar in the Department of Bioengineering and Electrical Engineering at UCLA before joining NC State as a faculty member in 2017. He is the recipient of the Bilsland Dissertation Fellowship at Purdue University, Honorable Mention of the Chancellor’s Award for Postdoctoral Research, and the CTSI Pathfinder Award at UCLA. His research aims to move molecular diagnostics from the bench to the palm by harnessing the unique imaging and sensing capability of mobile phones and nanomaterials. Focused research areas include point-of- care (POC) diagnostics, miniaturized imaging and sensing devices, genetic testing, plasmonic nanomaterials, and implementation of sensing technologies for mobile health and plants.
