The WestNile 4K Project is a partnership between West Nile virus surveillance laboratories and academic institutions across the United States. Our main goal is to provide real-time high definition reconstructions of the micro- (e.g., city/county) and macro-level (e.g., state/country) spread and evolution of West Nile virus by sequencing more than 8,000 virus genomes from infected birds, mosquitoes, and patients.
The data generated as part of this project will be immediately released to the public, and along with other entomological data, will be used to uncover local transmission dynamics. Analyses and visualizations will also be made publicly available in real-time as data are produced. As little progress has been made in effectively controlling West Nile virus outbreaks since its emergence in the United States two decades ago, our goal is to use fine-scale genomics-based transmission networks and extensive experimental studies to inform public health responses and help design future targeted control measures.
To learn more about the first twenty years of West Nile virus spread and evolution in the Americas and some of the background behind the WestNile 4K Project, read our recent review in PLOS Pathogens.

Leadership

Nate is trained as an arbovirologist, and has used his diverse background in private, government, and academic research to develop molecular strategies to detect, track, and understand mosquito-borne virus outbreaks. Having studied the ecology and evolution of West Nile virus during his Ph.D., a primary objective in his lab is to expand this work into using genomic epidemiology to inform targeted control measures.

These experiences have led Ryan to explore how mosquitoes transmit diseases like malaria and Zika virus. Ryan also oversees mosquito and West Nile virus surveillance in the state of Iowa, working closely with local and state public health partners to monitor potential disease outbreaks and to investigate the epidemiological factors that contribute to West Nile virus transmission. Ryan is a member of the Midwest Regional Center for Vector-borne disease, leading efforts to enhance the capacity to anticipate, prevent, and control vector-borne diseases.

Marc A. Suchard, M.D./Ph.D is a Professor at the University of California in Los Angeles (UCLA). He received a bachelor’s degree in biophysics from the University of California, Berkeley in 1995 and spent two years at Oxford University as a British Marshall Scholar. He then earned his Ph.D in biomathematics from the UCLA in 2002 and continued for a M.D. degree, which he received in 2004, also from UCLA.
His research is on the forefront of high-performance statistical computing. He is a leading Bayesian statistician who focuses on inference of stochastic processes in biomedical research and in the clinical application of statistics. His training in both Medicine and Applied Probability help bridge the gap of understanding between statistical theory and clinical practicality.
He has been awarded several prestigious statistical awards such as the 2003 Savage Award, the 2006 Mitchell Prize, as well as a 2007 Alfred P. Sloan Research Fellowship in computational and molecular evolutionary biology and a 2008 Guggenheim Fellowship to further computational statistics. Recently, he received the 2011 Raymond J. Carroll Young Investigator Award for a leading statistician within 10 years post-Ph.D. He is an elected Fellow of the American Statistical Association.
