Biography

Our research at the Laboratory of Virus Evolution (LoVE) has been to apply computational and experimental methods at the intersection of medicine, epidemiology and population genetics to identify the determinants of transmission and evolution at various spatio-temporal scales. We have focused on disease surveillance, genome sequencing and the integration of genomic data with clinical, epidemiological and immunological data that are generated through disease surveillance and laboratory experiments using phylogeny based methods. These include, to investigate factors affecting the diversity and evolution 
of pathogens in their natural reservoirs such as birds and bats; in livestock production systems; to elucidate origins of human pandemics; and to infer factors affecting the transmission of human pathogens as driven by host innate and adaptive immune systems, such as influenza, Enterovirus 71 and Dengue.

A unified framework to study infectious disease dynamics. 

A complex interplay of viral, host and ecological factors shape the emergence, evolution and spatio-temporal incidence of rapidly evolving pathogens. The improvement of large scale surveillance and sequencing efforts with the recent unification of epidemiology, ecology and evolutionary genetics has had a profound impact on infectious disease studies and a growing influence on pandemic preparedness and response (for example, the ability to estimate the basic reproductive number (R0) of an epidemic using sequence data), presenting a unique opportunity to develop novel methodologies to incorporate multiple streams of data to understand infectious disease dynamics.
