Area of Expertise:

  • Impact of Climate Change on Coastal Ecosystems
  • Land Use Change
  • Microbial Processes
  • Nutrient Pollution
  • Tidal Freshwater and Salt Marshes


Changes in tidal marsh ecosystems may be an early predictor of future scenarios of climate change and sea level rise. Dr. Weston is an expert in this area, focusing his ongoing research on the delicate microbial communities found in salt marshes. He can also discuss carbon cycling, or the exchange of carbon between the biosphere, atmosphere, oceans and geosphere, and nitrogen cycling, both vital to an ecologically healthy planet. The contributing effect of land use such as agriculture, deforestation and building development on climate is another area of Weston's expertise.

About Villanova

Since 1842, Villanova University’s Augustinian Catholic intellectual tradition has been the cornerstone of an academic community in which students learn to think critically, act compassionately and succeed while serving others. There are more than 10,000 undergraduate, graduate and law students in the University's six colleges – the College of Liberal Arts and Sciences, the Villanova School of Business, the College of Engineering, the College of Nursing, the College of Professional Studies and the Villanova University Charles Widger School of Law. As students grow intellectually, Villanova prepares them to become ethical leaders who create positive change everywhere life takes them.
