Recent research has focused on the spatial analysis of antibiotic resistance patterns among bacteria in metal contaminated streams and estuaries in the Southeastern US. This involved the readily applicable methodology of geostatistical variograms and cross-variograms to assess the degree of spatial correlation in resistance prevalence and the relationship between prevalence and metal concentration in the sediments.

Other research topics include:

• Statistical thinking and weight-of-evidence methods for ecological data analysis
• Logistic regression modeling of wind speed effects on wetland surface temperature (IR) measurements
• Applying ecosystem concepts to internet social networking and the contribution measurement niche
• Life history tradeoffs between energy allocation to size and shape vs. reproduction in fish
