Jia-Jin Jason Chen, PhD, is currently a Distinguished Professor of Department of Biomedical Engineering, National Cheng Kung University (NCKU), Tainan, Taiwan. Dr. Chen received the B.S. degree from Chung Yuan Christian University, Chung- Li, Taiwan, in 1980, and the M.S. and Ph.D. degrees from Vanderbilt University, Nashville, TN, in 1987 and 1990, respectively, all in biomedical engineering. Since 1997, he has been a professor at Department of Biomedical Engineering, NCKU. He was founding chairman of the undergraduate biomedical engineering program in 2011 after 22 years of graduate school only program at NCKU. Another important service work for Dr. Chen is his two-term committee member for Department of Industrial Technology (DoIT), Ministry of Economic Affairs, ROC. This position allowed Dr. Chen to oversee the grant proposals for medical device development in Taiwan. He also serves as Member of National Health Research Institute (NHRI, Taiwan), similar to NIH in USA, extramural research committee. Dr. Chen is currently the Executive Editor-in-Chief of Journal of Medical and Biological Engineering (JMBE), published by Taiwanese Biomedical Engineering Society. Dr. Chen has promoted the JMBE to be listed in Science Citation Index (SCI) in 2008 and ranked as one of the best regional journals on biomedical engineering with a rejection rate more than 70 %. Dr. Chen is pioneer for promoting neural engineering in Taiwan. His previous work on electrical stimulation cycling project has been focused on control strategy as well as brain mapping using near infrared spectroscopy (NIRS) for investigating neural plasticity of stroke subjects. He recent works also involved in repetitive transcranial magnetic stimulation (rTMS), transcranial direct-current stimulation (tDCS) and optogenetic stimulation for rodent animals of parkinsonism. Dr. Chen has been very actively working on the implantable biomicrosystem for in-vivo dopamine sensing as well as microstimulation for bladder control in animal studies. His present research activities involve biomedical signal processing, neural engineering, neuromodulation, neural/neuronal interfaces, and implantable biomicrosystem.
