The first semester of our Analytical Chemistry path is crazy! We needed to take the course 621, we needed to be teaching assistants, and we needed to rotate to join a research lab. I still remembered at the end of the first semester, I finished the course 621, got a good evaluation from both the teaching professor and students, and joined my dream lab (Prof. Lingjun Li). That was the happiest moment during my graduate school. Any challenge in these five years was a piece of cake compared with the first semester. I am really grateful for this progress design. One should be the first to bear hardships and the last to enjoy comforts.
I am Pingli Wei, a Ph.D. candidate of the Chemistry Department in Dr. Lingjun Li group. My research focuses on MS-based targeted and untargeted omics analysis. I have established multiplex isobaric (DiLeu) and isotopic (iDiLeu) labeling strategies for untargeted and targeted metabolomics study and applied it to biomarker discovery in human CSF and mice urine for AD and LUST study. I have also developed a novel MS approach for comparative neuropeptide characterization with a decision-tree driven MS method and applied it to human pituitary tumors, subcommissural organ, and PTSD study. Besides, I integrated metabolomics, peptidomics, and proteomics to investigate how the host immune system is shaped by human microbiome during infection. I am the first author of seven peer-reviewed articles and present my research at different symposiums and conferences.
