Professor Dr. Shuying Liu (1943.1-2023.11): A Devoted Mass Spectrometrist and Esteemed Mentor.

A year has gone by, and it is still hard to believe that Dr. Shuying Liu had left us on November 22, 2023. Most her colleagues and friends remember vividly her passionate images captured in the talk she filmed for the Chinese Mass Spectrometry Conference 2020-2023 in June 2023. In that video, Dr. Liu reviewed the progresses made in China's mass spectrometry field over the last 40 years and urged young mass spectrometrists to continue the work and forge an even more luminous future. Dr. Liu dedicated nearly 60 years to mass spectrometry research since 1965. As a renowned scholar, a professor of the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and Changchun University of Chinese Medicine and the founder of Jilin Ginseng Academy, Dr. Liu was a frequent and inspiring presence at academic conferences. Dr. Liu's talk, as always, resonated deeply with the audience, but nobody knew that would be the very last talk presented by her. Her demeanor was brimming with the same zest that had always characterized her presence, which made the disheartening news of her passing particularly jarring. Coming to terms with her departure is no easy feat; we find solace in envisioning her still in our midst, tirelessly dedicating herself to the mass spectrometry research she so deeply cherished.
