My research is founded on an integrative approach combining molecular, morphological, ecological and behavioural data with modelling techniques. My work ranges from:

  • elucidating the proximate and ultimate causes of speciation and the interplay between natural and sexual selection
  • studies on species distributions and population dynamics (e.g. range shifts/contractions/expansions)
  • predictions about the impact that current/future change (e.g. climate change, invasive species, habitat change) will have on species ranges, genetic diversity, connectivity between populations and diseases
  • studies on host-pathogen interactions with particular attention to pathogen’s reservoirs, modes of infection, and transmission and their impact on host fitness

Over the last decade, I have extensively (and still do) studied the White-Nose Disease, an emerging infectious disease caused by a fungus and affecting bats. I focus as much on the bat part as on the fungi part.

Teaching: population genetics and genomics, biostatistics, ecology, bat research.

Keywords: genetics; Chiroptera; speciation; population structure; host-pathogen
