Samantha Chapman, Ph.D.
Associate Professor, Department of Biology

Area of Expertise:

  • Biodiversity Loss
  • Invasive Species
  • Fire and Insect Damage to Ecosystems
  • Carbon Storage and Sequestration


Climate change, encroaching development, and accelerating environmental degradation of natural habitats pose a serious threat to an increasing number of plant and animal species. Dr. Chapman researches and can discuss leading issues and possible solutions to reversing biodiversity loss.

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.
