Training Group:


Mentor / Lab:

Dr. Andy Tao

Specific Research Area / Project:

Phosphoproteomics, Quantitative proteomics

Undergraduate Institution:

University of Science and Technology of China

Research Profile:

The phosphorylation modification is universally involved in human diseases including cancer. To understand the complex phosphorylation signaling requires the identification of substrates targeted by specific protein kinases. My research has been focusing on the proteomic method development for identifying the substrate specificity and potential substrates for protein kinases. The method called Kinase Assay Linked Phosphoproteomics (KALIP) has been demonstrated to be sensitive and has low false discovery rate for identifying direct kinase substrates. This high throughput method will benefit the signaling transduction society for substrate screening.

About Me:

I have been grateful to have the wonderful opportunity to join the PULSe program with its many diverse research directions from which to choose. During the rotation, I experienced four different types of research, including bioinformatics, plant biology, biotechnology and structure biology. Among them, the power of mass spectrometry based proteomics attracted me, so I decided to join Andy Tao’s group and conducted a series of method development research in the next several years. My PhD training has dramatically changed my mind regarding methodology in biological research. My career goal is to be a system biologist who combines both biotech and basic science into an art of research.
