Dr. Ljiljana (Lili) Paša-Tolić received her PhD in Chemistry at the University of Zagreb in Croatia, was a postdoctoral fellow at Pacific Northwest National Laboratory (PNNL) and visiting scientist at the National High Magnetic Field Laboratory. Today she is a Laboratory Fellow and Lead Scientist at the Environmental Molecular Sciences Laboratory (EMSL) located at PNNL. She is known for her pioneering contributions to mass spectrometry, high-throughput, and top-down proteomics, including the development of transformative instrumentation and methods for biological and environmental research. Dr. Paša-Tolić has authored more than 300 peer-reviewed publications; presented at more than 150 seminars, conferences, and workshops; and served at numerous editorial and advisory committees. She was a founding organizer to the worldwide Consortium for Top-Down Proteomics (CTDP), a nonprofit corporation that works toward the goal of accelerating “the comprehensive analysis of intact proteins and their complexes” and is currently serving on the CTDP Board. She has mentored more than 50 students and post-doctoral fellows, and organized several conferences, workshops, symposia, and schools focused on various aspects of analytical chemistry, omics, and mass spectrometry. In 2019, 2021 and 2024, she was selected for the Analytical Scientist Top 100 Power List, recognizing her pioneering contributions to high resolution mass spectrometry for applications ranging from environmental ecology to medicine, and she received the Jochen Franzen Award from the International Mass Spectrometry Foundation in 2024 for “outstanding contributions to innovations in structural, spatial and/or separation analysis with mass spectrometry”. Dr. Paša-Tolić was elected to the Washington State Academy of Sciences (WSAS) in 2021 and is currently serving on the WSAS Board.
