Kaikai Chen joined UCAS as an Associate Professor in January 2023. Prior to this, he worked as a Research Associate at the Ulrich Keyser's group at the Cavendish Laboratory, University of Cambridge, starting from August 2017. He obtained his PhD in Engineering from Tsinghua University in June 2017, with a diverse background in engineering, biology, and physics. His research interests are mainly focused on biophysics and bionanotechnology, with a particular emphasis on nanofluidics, nanopore sensing, and DNA nanotechnology. Kaikai Chen has authored over 20 papers published in well-known journals such as Nature Physics, Nature Nanotechnology, Nature Communications, Advanced Materials, ACS Nano, Nano Letters, and Biophysical Journal, among others. His research findings have been featured by Phys.org, Nanowerk, ScienMag, Bioengineer.org, and other media outlets.
