Research interest

I study the evolution of influenza viruses by applying the principles of population genetics to deep sequencing data with the goal of understanding how both inter- and intraspecies transmission events affect genetic diversity and fitness of entire population of influenza virus. Better characterization of these bottleneck events will improve our understanding of human spillover infections and better equip us to predict cyclical influenza pandemic events.
