About Treasurer

Lingjun Li

University of Wisconsin

Candidate Statement
ASMS is my scientific home—It has had a tremendous impact on my professional career.  I attended my first scientific meeting as a second-year graduate student in 1997 and have participated in every ASMS annual meeting since, drawn by the exciting science and the incredible people in this community.  I received my first external research grant as a Principal Investigator through the ASMS Research Award in 2004.  It is a privilege to have the opportunity to give back, and I am honored to be nominated for the ASMS Treasurer position. I am eager to contribute to the continued excellence and financial stewardship of a society that has profoundly shaped my scientific journey. With extensive experience managing large-scale research programs and mentoring the next generation of mass spectrometrists, I am committed to ensuring that ASMS remains a vibrant, inclusive, and fiscally sound community for all its members.

Lingjun Li received her B.E. in Environmental Analytical Chemistry from Beijing University of Technology and her Ph.D. in Chemistry from the University of Illinois at Urbana-Champaign under Jonathan Sweedler. She completed postdoctoral training at Pacific Northwest National Laboratory with Dick Smith and at Brandeis University with Eve Marder. Dr. Li is currently the Vilas Distinguished Achievement Professor and Charles Melbourne Johnson Distinguished Chair in Pharmaceutical Sciences and Chemistry at the University of Wisconsin–Madison.

Dr. Li’s research centers on MS-based neuropeptidomics, glycoproteomics, lipidomics, and spatial omics, integrating chemical tagging, ion mobility MS, and single-cell imaging to study molecular heterogeneity in neurodegenerative diseases and cancer. Her lab has discovered over 500 novel neuropeptides and developed high-throughput isobaric tagging strategies (DiLeu, DiPyrO, SUGAR tags), enabling up to 21-plex quantitation. She pioneered single-cell MS imaging and tissue expansion MS imaging (TEMI), contributing transformative insights into disease biology. Dr. Li has published over 400 peer-reviewed articles, holds multiple patents, and her work is supported by NIH, NSF, and other agencies. She has received numerous honors, including the ASMS Research Award, ASMS Biemann Medal, NSF CAREER Award, NSF Special Creativity Award, Sloan Fellowship, and Pittcon Achievement Award, and has been named to the Analytical Scientist Power List four times.

A dedicated ASMS member for nearly 30 years, Dr. Li serves as an Associate Editor for JASMS and on the advisory board of Mass Spectrometry Reviews. She is Guest Editor for special issues in Analytica Chimica Acta and npj Imaging. Her ASMS service includes the Education and Asilomar Conference Committees, co-organizing the Sanibel and Asilomar Conferences. She also co-organized US HUPO conferences (2018, 2023), PacifiChem symposia, Wisconsin Human Proteomics Symposia, and the 2025 International Single-Cell MS Conference. She served on the US HUPO Board (2015–2021), was President of CASMS (2015–2017), and is the current Chair of its Board. She also mentors through Females in Mass Spectrometry (FeMS).  Dr. Li is deeply passionate about training the next generation of scientists, having directly supervised over 100 graduate students, including 73 Ph.D. recipients, and numerous postdocs -- many now in faculty or industry leadership roles.
