Parviez Hosseini, senior research fellow at EcoHealth Alliance, focuses his work on studying vector-borne pathogens. As a mathematician and ecologist, Parviez uses his critical modeling skills to understand how diseases are transmitted from animal to animal and then oftentimes animal to human.
"Our modeling work is crucial to reducing the impact of a disease in that it predicts exactly the area most threatened by a disease emergence. Once an area of risk is identified, EcoHealth Alliance works to ensure that processes are in place that will prevent said disease from emerging and causing economic loss or human casualties." - Parviez Hosseini
Parviez studies and models Rift Valley Fever, a mosquito-borne disease originated in Africa, which infects and kills livestock, often leading to great economic losses within local communities. This disease is transmittable to humans, often sickening them with nausea, fever, and dizziness, and in rare cases leading to eye or brain disease. Parviez also studies the lesser-known Chikungunya virus, also insect-borne, that causes crippling joint pain and fever in infected humans within Africa and Asia.
Parviez's work takes him across the globe from the United States to Europe and from Africa to Asia, where he liaises with other partners to collect outbreak data and disease information in order to help him more acutely model the risk of future disease spread. Parviez's computer models help EcoHealth Alliance develop sound evidence about these diseases, including understanding the economic cost of disease and how climate change might increase disease spread. This data enables the organization to begin on the ground action in the fight against these diseases.
Parviez earned his B.S. in Applied Math - Biology from Brown University and Ph.D. in Biological Sciences from the University of California Santa Barbara. He conducted his postdoctoral research at the Lab of Ornithology at Cornell University, and at Princeton University.
Parviez's research has been published in various prestigious journals such as American Naturalist, Ecology, Nature, and Ecological Modeling. He is the recipient of several fellowships including the NSF RTG/GRT Fellowship in Spatial Ecology at UCSB and a fellowship at the National Center for Ecological Analysis and Synthesis. He has served as a reviewer for American Naturalist, Ecology, Ecology Letters, Journal of Animal Ecology, PLoS Medicine, Population Ecology, and Proceedings of the Royal Society B: Biological Sciences.
