Shien-Fong Lin received the B.S. degree in communication engineering from National ChiaoTung University, Taiwan, R.O.C., and the M.S. and Ph.D. degrees in biomedical engineering from Northwestern University, Evanston, IL. He joined the Living State Physics Group at Vanderbilt University, Nashville, TN, in 1992 and pioneered cardiac optical mapping technique to measure electrical excitation and propagation in cardiac tissue. In 2001, he joined the Electrophysiology Research Group at Cedars-Sinai Medical Center, Los Angeles, CA, and was an Associate Professor at David Geffen School of Medicine, University of California, Los Angeles. He is now at the Krannert Institute of Cardiology, where he is a Professor of Medicine at the Indiana University School of Medicine, Indianapolis. His research interests include cardiac electrophysiology, control of arrhythmias, biomedical optics, and biomedical image processing. Dr. Lin won first prize in the Young Investigator Competition in North American Society of Pacing and Electrophysiology in 1998.
