<h2><strong>Biography</strong></h2>
Dr. Wei-Chiang Lin is an Associate Professor of the Department of Biomedical Engineering at Florida International University, where he has been since 2004. From 2015 to 2017 he served as the interim chair of the Department. He is also the co-director of the Orthotics and Prosthetics track, a self-supporting program within the Master’s Program of Biomedical Engineering. Dr. Lin obtain 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, under the supervision of Dr. A.J. Welch and Dr. Massoud Motamedi, from the University of Texas at Austin in Austin, TX. Upon completion of his Ph.D. degree in 1997, he received a postdoctoral fellowship from the W. M. Keck Foundation FEL Center and jointed the Department of Biomedical Engineering at Vanderbilt University in Nashville, TN. In 2000 he because a Research Assistant Professor in the Department of Biomedical Engineering. Dr. Lin’s research focuses 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 National Institute of Health, Department of Defense, Thrasher Research Fund, and American Heart Association.
<h2><strong>Research</strong></h2>
Dr. Lin’s research involves developing non-destructive optical and mechanical technologies that can detect disease development and tissue injuries in vivo. These techniques can be either one-dimensional (i.e., point detection) or multi-dimensional (i.e., imaging). The potential medical applications for such techniques, once developed, are abundant. For example, they may be used intraoperatively to guide tumor resection and to monitor the progression of a novel therapy.

<strong>Research related to neuroscience and neuroengineering</strong>

Dr. Lin’s research team at Miami Children’s Hospital is interested in developing new approaches to diagnose and treat pediatric epilepsy and brain tumor. Currently, their research efforts focus on addressing the intraoperative needs of pediatric brain tumor and epilepsy surgery. For example, the team has developing an effective surgical guidance system that can differentiate abnormal (i.e., neoplastic and epileptic) brain area from the normal one in vivo based on their intrinsic properties.

<strong>Research related to cardiovascular diseases</strong>

Precise, timely delivery of adequate treatment for myocardial infarction (MI) is essential for both traditional treatments and developing therapeutic concepts such as cellular cardiomyogenesis. While many pathological and physiological alterations in the left ventricle (LV) myocardium have been identified post-infarction, on-site acquisition of this information remains unavailable in in vivo and intraoperative situations.

The long-term goal of this research project is to develop an effective technique, based on optical spectroscopy and fiber optics, in order to detect the pathophysiological changes in myocardium resulting from infarction in vivo. Once developed, this technique will be used in conjunction with cardiac catheterization to allow physicians (1) to identify viable myocardium within and around infarcts; (2) to gain specific knowledge regarding an infarct’s age and size; and (3) to assess microvascular damage surrounding infarcts.
