Intracellular membrane trafficking: molecular mechanisms responsible for the generation and maintenance of intracellular membrane-bound compartments, mechanisms and machinery which maintain high specificity of vesicle tethering and docking.
Golgi vesicle tethering factors: role of the Conserved Oligomeric Golgi (COG) complex in the intra-Golgi retrograde membrane trafficking, the COG complex interaction with SNAREs, Rab-GTP and the COPI vesicle coat.
Protein glycosylation disorder: depletion of the COG complex which is accompanied by accumulation of COG complex dependent (CCD) vesicles, cargo of non-tethered CCD vesicles, production of underglycosylated proteins.

Research activity

PhD research at the Department of Physiology, UAMS.
COG complex - mediated recycling of Golgi enzymes.
Intracellular membrane trafficking is mediated by a large variety of molecules. The COG complex is a tethering molecule, which resides on the cis-Golgi. Most likely it functions in tethering of transport intermediates to the proper Golgi compartments. Depletion of the COG complex ultimately leads to the development of defects in protein glycosylation.
2003 - 2004
Postgraduate research at the Department of Virology, NMUU.
Adsorption activity of natural smectites.
This research was aimed on the investigation of physical factors affecting adsorbtion activity of smectites. Rotaviral infection constitutes twenty percent of all newborn infectious diseases. Natural smectites (sorbents) adsorb viruses, thus eliminating viral infection.
