Mission: The mission of the Environmental Assessment and Information Technology Program (EAIT) is to develop modern methods of management of vectorborne disease research and surveillance data, to develop predictive models based on these data, and to facilitate sharing of research and surveillance data among California agencies cooperating in the prevention and control of vectorborne diseases in California. Included in this mission is the development of public and collaborative websites providing interactive information on vectorborne diseases in California.
Support: Research and development activities relating to EAIT are supported by grants to Dr. William Reisen and Dr. Chris Barker from the National Institutes of Health, the National Oceanic and Atmospheric Administration, the Centers for Disease Control and Prevention, the National Aeronautics and Space Administration, the University of California Mosquito Research Program, and the Coachella Valley, Greater Los Angeles County, Kern, and Sacramento-Yolo Mosquito and Vector Control Districts.
Personnel: Personnel are stationed on Old Davis Road south of the main UCD campus. EAIT is under the direction of Dr. Bruce Eldridge. Bborie Park serves as Programmer/Network administrator. He is the author of the California Vectorborne Surveillance Gateway. Dr. Chris Barker is an Assistant Research Epidemiologist who is developing models to predict mosquito abundance and mosquitoborne viral activity in California based on climatic, edaphic, and land-use factors. Dr. William Reisen coordinates activities of the program with those of the Arbovirus Research Program that he directs.
Collaboration: There is extensive collaboration with Drs. Daniel Cayan and Michael Dettinger and Mary Tyree of the Scripps Institution of Oceanography at University of California, San Diego. These scientists are relating temporal and spatial changes in mosquito abundance and virus activity to long and short term climatic variation. Remotely sensed data are included in collaboration with Forrest Melton and Dr. Brad Lobitz of NASA Ames Research Center. Mathematical models of West Nile virus are being developed in collaboration with Dr. David Hartley and Dr. Tianchan Niu of Georgetown University and Dr. Arnaud Le Menach of the Health Protection Agency, London.
