BiographyBrief Bio: Xia Liu received her Ph.D. in Institute of Microelectronics from Tsinghua University, Beijing, China, in 2017. From September 2012 to October 2013, she was a visiting student in University of California at Berkeley. From August 2017 to October 2018, Dr. Liu was entitled as a Wen H. Ko Fellow at Case Western Reverse University (USA). Currently, she is a researcher scientist in Microsystems laboratory, EPFL. She has demonstrated outstanding effort to research and explorations in micro/nanoscale devices and integrated systems, both at the frontiers of fundamental device physics and toward cutting-edge micro/nanotechnologies for emerging applications. She has authored or co-authored more than 10 peer-reviewed journal papers during last two years. With her PhD dissertation titled “Cardiomyocyte-Driven Energy Harvester and Ultrahigh Piezoelectric Nanofibers”, she received the “Tsinghua University Excellent Doctoral Dissertation Award, First Prize” in 2017. She also received the title of Excellent Ph.D. Graduate of Beijing in 2017. Her current research interest is focused on micro energy harvesting, advanced fabrication of 2D materials, devices and applications.
