Overview

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.

Recent Data Releases

October 1, 2019 in Data

Arizona, Idaho, Iowa, and Washington

Collaboration and Data Sources We received 15 samples of RNA extracted from birds that tested positive for West Nile virus from Dan Bradway, Becca Wolking, and Marla Francis from the Washington Animal Disease Diagnostic Laboratory (WADDL). The samples were spread across five years: 1 from 2013, 1 from 2014, 5 from 2015, 2 from 2016, and the remaining 6 from…

Leadership

Nate Grubaugh

Assistant Professor, Yale School of Public Health

Nathan D. Grubaugh, M.S., Ph.D. is an Assistant Professor at the Yale School of Public Health in the department of Epidemiology of Microbial Diseases. He spent ~7 years working in the biotech sector before earning a M.S. in biotechnology from Johns Hopkins University in 2011 and a Ph.D. in microbiology from Colorado State University in 2016. Nate did his postdoctoral training in pathogen genomics under the guidance of Kristian Andersen at Scripps Research before joining the faculty at Yale in 2018.

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.

Ryan Smith

Assistant Professor, Iowa State University

Ryan C. Smith, Ph.D. is an Assistant Professor in the Department of Entomology at Iowa State University. He earned his degree in molecular biology at the University of California Riverside working on mosquito genetics, then did his post-doctoral training at the Johns Hopkins Bloomberg School of Public Health focusing on mosquito host-pathogen interactions. Ryan joined the faculty at Iowa State in 2015 establishing a research program with both lab- and field-based components to better understand mosquito-borne disease transmission.

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 Suchard

Professor, UCLA

Professor
University of California, Los Angeles

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.

Kristian Andersen

Associate Professor, Scripps Research

Kristian Andersen, PhD is an associate professor in the Department of Immunology and Microbiology at Scripps Research, with joint appointments in the Department of Integrative Structural and Computational Biology, and at the Scripps Research Translational Institute. Over the past decade, his research has focused on the complex relationship between host and pathogen. Using a combination of next-generation sequencing, field work, experimentation, and computational biology he has spearheaded large international collaborations investigating the spread and evolution of deadly pathogens, including Zika virus, Ebola virus, West Nile virus, and Lassa virus. His work is highly cross-disciplinary and exceptionally collaborative.

Kristian earned his doctoral degree from the University of Cambridge in immunology and performed postdoctoral work in Pardis Sabeti's group at Harvard University and the Broad Institute. He has received several awards, including the Max Perutz Prize in 2008, a Carlsberg Foundation Fellowship in 2009, and was chosen as a PEW Biomedical Scholar in 2016.
