I maintain active research interest in (a) disease mapping and spatial analysis of public health data, (b) food production and food accessibility issues in the Caribbean, and (c) urban revitalization in the Caribbean. In the field of public health GIS, my research revolves around the use of GIS for visualizing and statistically analyzing spatial patterns associated with different types of diseases. Currently, my focus is on geostatistical methodologies for detecting disease clusters and modeling of infectious disease patterns. I have collaborated with public health officials in Jamaica to develop GIS capability in the Ministry of Health in Kingston, and in the various health regions of that country. Recently, I have collaborated with CARES researchers investigating neighborhood patterns associated with Out of Hospital Cardiac Arrest in several US cities.
