GIScCE Researchers Present at the ASTMH Annual Meeting

GIScCE professor Dr. Mike Wimberly, along with postdoc Ting-Wu Chuang and graduate student Alemayehu Midekisa, presented research results at the 60th annual meeting of the American Society for Tropical Medicine and Hygiene (ASTMH). The following poster presentations were delivered: 

A computer system for forecasting West Nile virus risk using earth observation data. Michael C. Wimberly, Ting-Wu Chuang, Aashis Lamsal, Alemayehu Midekisa, Geoffrey M. Henebry, Gabriel Senay, Michael B. Hildreth, and Yi Liu. 

Environmental Determinants of West Nile Virus Epidemic in South Dakota throughout 2003 to 2007. Ting-Wu Chuang, Lon Kightlinger, and Michael C. Wimberly. 

Forecasting and Monitoring Malaria Risk in the Amhara Region, Ethiopia. Alemayehu Midekisa, Gabriel Senay, Geoffrey M. Henebry, Paulos Semuneguse, Abere Mihretie, and Michael C. Wimberly. 

Dr. Mike Wimberly and colleagues travel to Ethiopia to initiate malaria early-warning project

In March 2009, Mike Wimberly, Gabriel Senay, and Geoff Henebry travelled to Ethiopia to meet with research partners and tour the highland regions that we will be studying as part of an NIH-funded research project. While in Addis Ababa, we met with representatives of the Anti-Malaria Organization (AMA) and GeoSAS International, a private consulting firm that provides geospatial analytical services. We also held meetings with faculty members from Gondar University and Bahir Dar University, and with public health officials from the Amhara Regional State Bureau of Health and the Federal Ministry of Health. Based on these meetings, we have developed formal partnerships with the AMA and GeoSAS to create a malaria case database and a GIS database that will be used in the development of an malaria early-warning system.

Dr. Geoff Henebry visits Hungary, Romania, China and Ethiopia

During a busy summer of international travel, Dr. Geoff Henebry visited Hungary, Romania, China, and Ethiopia. In June he was hosted by Dr. Sándor Bartha at the Institute of Ecology and Botany of the Hungarian Academy of Sciences. It had been over a decade since Geoff was working with Sanyi and others on succession in abandoned croplands in the Kiskunság, the sandy hills of central Hungary located between the Duna (Danube) and Tisza rivers. In addition to revisiting former field sites in the Kiskunság National Park, Geoff explored the landscapes north of Lake Balaton in western Hungary and the Hortobágy National Park in eastern Hungary.  Traveling by train from Budapest to Sibiu, Romania, Geoff met up with several colleagues from the SDSU Geography Department who were being graciously hosted by the Dean Ion Velcea and the Faculty of Tourism Geography of the “Dimitre Cantemir” Christian University.  Field trips included various locations around Transylvania, including Sighişoara, the medieval walled city where Vlad Dracul lived for a time, and to a special symposium of the Romanian Geography Society on montane agrotourism in the town of Vaideeni. The Second Romanian-American Scientific Session was held on June 13 at “Dimitre Cantemir” and featured presentations by SDSU faculty.  In July Geoff traveled to Kaifeng, China to participate in a NASA sponsored workshop on the dryland ecosystems of East Asia: In August Geoff traveled to the Amhara region of Ethiopia for the NIH project led by Dr. Mike Wimberly  (described in another news item).
