Dr. Wei-Chiang Lin is an Associate Professor of the Department of Biomedical Engineering at Florida International University, where he has been since 2004. He served as the interim chair of the Department from 2015 to 2017. Also, he is the co-director of the Orthotics and Prosthetics track, a self-supporting program within the Master’s Program in Biomedical Engineering. Dr. Lin obtained his B.S. degree in Biomedical Engineering from the Chung-Yuan Christian University in Taiwan, ROC in 1987. He received his M.S. and Ph.D. degrees in Biomedical Engineering from the University of Texas at Austin under the supervision of Dr. Ashley J. Welch and Dr. Massoud Motamedi. When he completed his Ph.D. degree in 1997, he received a postdoctoral fellowship from the W. M. Keck Foundation Free Electron Laser Center and joined the Department of Biomedical Engineering at Vanderbilt University in Nashville, TN, and he became a Research Assistant Professor in the Department in 2000. Dr. Lin’s research is focused on developing engineering solutions for diagnosing and treating tissue disorders and injuries, with a strong emphasis on pediatric brain disorders. To date, his research projects have been funded by the National Institute of Health, Department of Defense, Thrasher Research Fund, and American Heart Association.


Dr. Lin’s research involves developing non-destructive optical and mechanical technologies that can detect the development of disease and tissue injuries in vivo. These techniques can be either one-dimensional (i.e., point detection) or multi-dimensional (i.e., imaging). When such techniques have been developed and tested, there is significant potential for their use in many medical applications. For example, they may be used intraoperatively to guide tumor resection and to monitor the progression of novel therapies.
