Dr. Chen’s Personal Information

Chiachung Chen, Ph.D.



Dr. Chen has studied the application of Biosystems engineering to Bio-industry and medicine. He received his Bachelor’s and Master’s degree in Agricultural Engineering from National Taiwan University in 1978 and 1980. He studied the processing engineering of agricultural products at the Agricultural Engineering Department, the Institute of Engineering and Science in the University of Minnesota from 1985 to 1988. The minor was Chemical Engineering. He received his Ph.D. in 1988. He served as an Associate Researcher in the Taiwan Agricultural Research Institute in Taichung, Taiwan in 1988. He was appointed as an Associate Professor of the Department of the Agricultural Machinery Engineering, National ChungHsing University in 1996, where he changed his research projects from agriculture to bio-industry. He was promoted as a Professor in 2000. His current research and scientific interest focus on Biomedical instrumentations, Sensing systems, Plant micropropagation, Modeling of orchids production and Protected culture in subtropical climate.
