Research Interests:
Molecular virology, molecular pathogenesis and evolution, molecular mechanisms of virus replication and adaptation to the environment.
The main interest in my group is tick-borne flaviviruses (TBFV), a genetically closely related pathogens that infect and are transmitted to humans and animals by infected ticks. Despite the close antigenic and genetic relationships, these viruses produce a variety of clinical manifestations that include asymptomatic infections, fevers, haemorrhagic disease, encephalitis and chronic diseases. We have developed a genetic system based on infectious clones of Tick-borne encephalitis virus, to study the molecular basis of virus pathogenesis and vector transmission and also to develop attenuated virus variants that could be used as the basis to develop a live attenuated vaccine. Recently we initiated a research on secondary RNA structures of flaviviruses that are the primary sites for interaction with viral and cellular proteins to form virus replication complexes, and their significance in the virus adaptation to vertebrate and invertebrate hosts.Finally, we use molecular epidemiological techniques to study virus taxonomy and evolution.
Currently Funded Research Projects:
