Kai Liu

Professor Kai Liu is a distinguished physicist currently serving as Professor and the Robert L. McDevitt, K.S.G., K.C.H.S. and Catherine H. McDevitt, L.C.H.S. Chair in Physics at Georgetown University. He previously held faculty positions at the University of California – Davis from 2001 to 2018, where he was promoted to full Professor in 2008. He earned his Ph.D. in Physics from Johns Hopkins University in 1998 and conducted postdoctoral research at UC San Diego.

• Ph.D. in Physics, Johns Hopkins University (1998)
• Postdoctoral Research, University of California – San Diego
• Faculty Member, UC Davis (2001–2018)
• Professor and Chair, Georgetown University (2019–present)

His research centers on the synthesis and experimental investigation of nanostructured materials, with a strong emphasis on nanomagnetism and spintronics. He explores topological spin textures such as magnetic skyrmions and chiral domain walls, magneto-ionic control of interfaces for energy-efficient electronics, high magnetic anisotropy materials like L1₀ FePt for magnetic recording, and 3D magnetic networks for neuromorphic computing. His work bridges fundamental physics with applications in low-dissipation information storage and nanoelectronics.

The recent trend in his publications reflects a deep focus on magneto-ionics, skyrmion manipulation, and multifunctional nanomaterials. His group pioneers the use of ion migration—particularly nitrogen and hydrogen—to reversibly control magnetic properties at room temperature, enabling next-generation non-volatile memory and neuromorphic devices. The integration of high-entropy alloys and 3D nanowire networks highlights a shift toward scalable, robust materials for real-world applications.

Professor Liu has received numerous prestigious honors and fellowships:

• Alfred P. Sloan Research Fellowship (2005)
• UC Davis Chancellor’s Fellowship (2007)
• Fellow, Institute of Physics (UK, 2011)
• Fellow, American Physical Society (2012)
• Fellow, IEEE (2016)
• Fellow, AAAS (2019)
• Fellow, National Academy of Inventors (2022)

He has served as Program Co-Chair for MMM 2007 and Intermag 2011, General Chair for MMM 2016, Associate Editor for APL Materials (2018–2019), and Chair of the IUPAP Commission on Magnetism (2021–2024). His research is supported by major grants and collaborations, though specific funding sources are not detailed in the text. He leads an active research group focused on advanced materials synthesis and characterization, contributing significantly to the fields of magnetic materials and quantum phenomena.
