Yiyi Yan received the B.S degree in electronic science and technology from Beijing University of Chemical Technology, Beijing, China, in 2017. She received the M.S. degree in electrical engineering from Université catholique de Louvain (UCLouvain), Louvain-la-Neuve, Belgium, in 2019. Currently, she is studying for the Ph.D. degree in applied sciences at ICTEAM institute, UCLouvain, Belgium. She published 7 articles in international journals and conferences. Her research interests are the characterization of advanced CMOS dielectric materials (high-k materials, Al2O3, and 2D hBN material), including the extraction of intrinsic material properties at nanometer scale, On-wafer RF & mm-wave measurements. Presently, she is working on the design and fabrication of RF switches based on memristor as well as the simulation of gas sensors.
