Penny Masuoka, MS

Adjunct Assistant Professor


Ms. Masuoka currently serves as Adjunct Assistant Professor in the Department of Preventive Medicine and Biometrics at the Uniformed Services University of the Health Sciences. Her research and academic focus is on the use of geographic information systems (GIS) and remote sensing in the field of public health. Prior to coming to USU, Ms. Masuoka worked at NASA's Goddard Space Flight Center for 24 years.

Predicting the Distribution of Vector-borne Disease
Diseases such as malaria, Japanese Encephalitis and dengue occur in areas that have environmental conditions favorable to the survival of the mosquito vectors of the disease. Remotely sensed satellite data can be used to map breeding habitats (such as rivers and lakes) and measure other variables such as temperature and rainfall. Environmental variables that are shown to be associated with an increase in mosquito populations are then used to predict the distribution of the disease.
