Dr. Ruijun Tian obtained his Ph.D. in analytical chemistry from Dalian Institute of Chemical Physics, Chinese Academy of Sciences in 2008 (Mentor: Dr. Hanfa Zou). He then moved to Canada for his postdoctoral training with Dr. Daniel Figeys at Ottawa Institute of Systems Biology, University of Ottawa (2008-2010) and Dr. Tony Pawson at Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital and University of Toronto (2010-2014). In 2014, he joined Department of Chemistry, Southern University of Science and Technology (SUSTech) as an associate professor. He is also adjunct professor of School of Medicine, University of Ottawa and Shenzhen Peoples hospital. His major research interest is precision medicine-oriented MS-based proteomics technology development and applications mainly in intercellular signaling of tumor microenvironment. He has published more than 50 research papers in Nature, PNAS, Angew Chem., Mol. Cell. Proteomics, Anal. Chem., etc. with H-index of 25 (Google Scholar). He received 2012 Young Investigator Award from International Association for Protein Structure Analysis and Proteomics (IAPSAP), Canadian Institutes of Health Research (CIHR) postdoctoral fellowship, and Presidents Scholarship from Chinese Academy of Sciences. He was the co-chairs for 2nd Young Investigator Symposium of CNHUPO and 5th China-Canada Systems Biology Symposium. He is the editorial board member for Frontiers in Endocrinolog and Austin Proteomics.
