Research interests
My research is focused on primary sensory neurons. The cell bodies of these neurons make sensory ganglia, including dorsal root ganglia (DRG), and are part of the peripheral nervous system (PNS).
These neurons convey sensory information from the both internal (e.g. viscera, muscles and bones) and external environment (skin) to central nervous system (CNS). Sensory neurons convey both innoxious and noxious stimuli. The latter is perceived in the CNA as pain. My research interest lies in investigating the molecular changes in sensory neurons that are associated with pathological pain. This is important in order. My lab uses variety of methods based on molecular biology, cellular biology, mouse transgenic and behavioural analysis to identify targets for novel and effective analgesic drugs.
