"The trickiness of Trichomonas genomes"
Since 2006, her group has been at New York University undertaking research into the biology and evolution of important human parasites. She is Program Director of the Center for the Study of Complex Malaria in India, an NIH-funded International Center of Excellence for Malaria Research. In 2010 she was awarded the Stoll-Stunkard Award from the American Society for Parasitologists; in 2012 she was elected a Fellow of AAAS; and in 2018 she was honored with a Julius Silver, Roslyn S. Silver, and Enid Silver Winslow endowed chair from NYU.
In the Carlton lab we use the tools of comparative genomics – whole genome sequencing and genomics, bioinformatics, molecular biology and population genetics – to study the biology and evolution of closely related strains or species of parasite. In medicine and global public health, the term parasite is used to describe a group of eukaryotic microbes and helminths that cause some of the world’s most devastating diseases. The parasites that we study include:
(1) Species of the malaria parasite Plasmodium: more than half the world’s population is at risk from malaria, and the disease causes ~216 million cases and ~655,000 deaths per year. The most deadly form of the parasite, Plasmodium falciparum, is found mostly in sub-Saharan Africa where it causes the deaths of children < 5 years old. Plasmodium vivax is the most common species outside Africa in South America and Southeast Asia, and is closely related to a group of species that infect Asian Old World monkeys from Taiwan to Sri Lanka, called the monkey malaria clade.
(2) The sexually transmitted parasite Trichomonas vaginalis and related trichomonads: T. vaginalis is the most common non-viral STI, and causes ~249 million cases per year world-wide. It is associated with increased risk of HIV-1 infection, and serious complications during pregnancy. Other trichomonads include Trichomonas tenax found in the mouth, Pentatrichomonas hominis a zoonotic gut parasite, and Tritrichomonas foetus a serious venereal pathogen that causes abortion in cattle.
(3) Other fascinating parasites such as species of the enteric pathogen Cryptosporidium, the bovine parasite Theileria, and Babesia.
Our research often begins with generation of a resource such as sequencing, assembly and annotation of a parasite’s genome. For example, we have been involved in the sequencing of P. falciparum , species of rodent malaria (Plasmodium yoelii yoelii , Plasmodium chabaudi chabaudi and Plasmodium berghei ), several strains of P. vivax [4, 5], several strains of the monkey malaria Plasmodium cynomolgi , and the first T. vaginalis genome .
