Title

Assistant Research Professor of Biochemistry

Biochemistry

Expertise

Prokaryotic and Eukaryotic voltage gated ion channel biophysics.
Electrophysiology, Molecular Biology, Biochemistry.
Conotoxin interaction and regulation of ion channel function in vitro and in vivo.

Profile

With the help of several electropgyisiological techniques I
am dedicated to explore structural and functional aspects of various ion channels. Such research is of great importance in the elucidation of the physiological roles of specific channel proteins, the signaling pathways they participate in, as well as their regulation in health and disease.
