Andrea L. Welker, Ph.D. P.E.

Area of Expertise:

  • Geotechnical Engineering
  • Engineering Sustainable Landscaping/Rain Garden Design
  • Stormwater Management


Dr. Welker is an authoritative source for stories that seek to present environmental engineering solutions to development and overbuilding, especially stormwater runoff. Her combined interest in geotechnical engineering and stormwater management has led Dr. Welker to investigate processes occurring in stormwater infiltration. As a leading member of the Villanova Urban Stormwater Partnership, Dr. Welker can speak about various methods of improving stormwater management, including how to achieve easy, economical, natural bioretention through the design and do-it-yourself construction of rain gardens.

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.
