Malaria Parasite Evolution & Genetics
My lab has studied the diversity, evolution, and genetics of a group of parasitic protists known as haemosporidians. This group includes the parasites that cause the disease malaria in humans, but also more than 600 other species that use other vertebrates - birds, lizards, bats, ungulates - as their hosts. We use these diverse parasites to better understand how the parasites have evolved to use hosts, invade cells, and digest hemoglobin.
Microbiomes of Wild Hosts
The microbiome, the collection of bacteria, archaea, protists, and viruses that live in and on another organism, is vital to the host's survival. My lab has studied the diversity of the bacteria that are associated with wild hosts such as bats, birds, and insects.
Genetics & Evolution of Other Parasites
In addition to haemosporidians, members of my lab have also studied the systematics, diversification, and evolution of many other parasites, such as heart worms, pinworms, ticks, and other blood parasites such as trypanosomes and hemogregarines.
