Ziqiang Guan
Research Professor in Biochemistry

We develop and apply mass spectrometry techniques to address biochemical and biomedical questions that are lipid-related. Research projects include:

1) Structural lipidomics

o Develop and apply high resolution tandem mass spectrometry-based lipidomics for the discovery, structural elucidation and functional study of novel lipids.

2) Elucidation of novel pathways/enzymes of lipid biosynthesis and metabolism

o Genetic, biochemical and MS approaches are employed to identify the substrates and pathways involved in lipid biosynthesis and metabolism

3) Identification of lipid biomarkers of genetic diseases and cancers

o Provide molecular insights into the disease mechanisms, as well as to serve as the diagnostic and prognostic tools of diseases.
