Mei-Chin Chen received her Ph.D. degree in the Department of Chemical Engineering, National Tsing Hua University, Hsinchu, Taiwan in 2008. She now is a Professor in the Department of Chemical Engineering, National Cheng Kung University, Tainan. Her research interest focuses on microneedle-based transdermal drug delivery, particularly on development of various polymeric microneedles for macromolecular delivery. She has designed three kinds of microneedle formulations for different clinical requirements, including dissolving microneedles for rapid delivery of insulin, degradable microneedles for sustained delivery of vaccines, and triggerable microneedles for on-demand delivery of anti-cancer drugs.
