Qing He, Ph.D.

Qing He, Ph.D.
Postdoctoral fellow, Huilin Li Laboratory


Dr. Qing He graduated from Shandong Normal University with a B.S. in biotechnology and Ph.D. in microbiology. Her graduate work focused on ­­­the structural and functional study of c-di-NMP related proteins, and the many biochemical experiments. Dr. He’s main lab competencies lie in ­­­cloning, protein purification, crystallization and small molecular and protein interaction tests. In 2021, she joined the lab of Dr. Karsten Melcher as a postdoctoral fellow.


Current research focus

Using cryo-EM and negative-staining, Dr. He investigates the structure and function of the MYC/JAZ/NINJA complex in order to elucidate interactions between JAZ and NINJA. Her work seeks to reveal the proposed transition from repressor to activator through altered interactions of a preassembled complex.
