About the Program

The Environmental Science program at Drexel University is located in the Department of Biodiversity, Earth and Environmental Science (BEES), and is committed to educating undergraduates for technical careers and graduate study in the diverse areas of environmental science. These areas are vital to understanding, conservation, and restoration of clean and healthy natural environments in the 21st century. The partnership between the Academy of Natural Sciences, America's oldest natural history museum, and Drexel University offers students unique opportunities to take a leadership role in ecology, environmental science and environmental policy, and to grow the scope, capacity and reputation of the natural sciences at the University. The philosophy of the Biodiversity, Earth & Environmental Science Department is “Experiential Learning Early and Often."

Environmental science is a multidisciplinary field designed to examine environmental problems and find solutions. This field requires understanding of a number of disciplines including biology, physics, and chemistry. Solving some of our environmental problems also requires knowledge of environmental policy, ethics, and scientific data analysis. 

The program has an integrated curricular approach designed around student laboratory and field investigations. The goal of this program is to give students not only knowledge about biology, chemistry, and ecology, but also the ability to use the tools and skills of a scientist. The program includes extensive use of computers in the laboratory and students make frequent oral and written presentations based on their laboratory projects.

Field experience electives may include trips to local aquatic and terrestrial habitats, such as streams, lakes, the John Heinz National Wildlife Refuge, New Jersey Pine Barrens, Delaware, Barnegat and Chesapeake Bays, and the Appalachian Mountains. Students are also encouraged to take advantage of study abroad options, including ENVS field courses. These programs often require early planning, so it is advisable for interested students to speak to their advisor about opportunities in their first year.

Concentrations are available in:

  • Ecology & Evolution
  • Applied Environmental Science

Notes about Environmental Science opportunities:

  • Field experience electives include quantitative environmental measurements in local aquatic and terrestrial habitats, such as streams, lakes, the Delaware Bay, the Poconos, and the New Jersey Pine Barrens (for example, Field Botany: NJ Pine Barrens; Ecology of the Pine Barrens; Marine Field Methods).
  • Students are required to consult frequently with their academic advisors for curriculum planning. Many of the graduate courses in environmental science are also open to qualified seniors who wish to become familiar with some of the applications in the field. Prerequisites and descriptions of available graduate courses appear in the graduate catalog.
  • The Equatorial Guinea: Bioko Island Study Abroad Program offers a unique opportunity for undergraduates and recent graduates to study tropical biodiversity and its conservation, with an emphasis on field work that takes advantage of Bioko Island's pristine rainforests ranging from sea level to over 10,000 feet in altitude, its seven species of rare monkeys, and its four species of nesting sea turtles. For more information, please visit the Drexel Study Abroad Office.

Writing-Intensive Course Requirements

In order to graduate, all students must pass three writing-intensive courses after their freshman year. Two writing-intensive courses must be in a student's major. The third can be in any discipline. Students are advised to take one writing-intensive class each year, beginning with the sophomore year, and to avoid “clustering” these courses near the end of their matriculation. Transfer students need to meet with an academic advisor to review the number of writing-intensive courses required to graduate.

A "WI" next to a course in this catalog may indicate that this course can fulfill a writing-intensive requirement. For the most up-to-date list of writing-intensive courses being offered, students should check the Writing Intensive Course List at the University Writing Program. Students scheduling their courses can also conduct a search for courses with the attribute "WI" to bring up a list of all writing-intensive courses available that term.
