Research Interests:
Biogeomagnetism and Biomineralization
(1) The mechanism of magnetoreception in animals
The earth’s magnetic field represents a very reliable, omnipresent source of information for all living organisms. A great deal of researches proved that many animals can use the geomagnetic field to orientation and navigation in their lives. The mechanism of magnetoreception in animals remains unknown. The biogenic magnetic minerals or the photopigments in retina has been postulated as an ideal magnetoreceptor. I am interested in studying the ultrastructure of biogenic magnetic minerals in animals using rock magnetic measurements and biological slicing technique.
(2) The biomineralization of nano-magnetic particles in ferritin
Iron biomineralization widely occurs in living organisms due to the fundamental role that iron plays in biological processes. Ferritin is a vital iron storage protein for all living organisms. It plays major roles in iron storage and iron detoxification. Recent years, ferritin was applied to reconstitute diverse novel nanomaterials within the protein shell by biomimetic syntheses in vitro. I am interested to investigate the mechanism of ferritin biomineralization.
