These factors enable students to build on their scholarship and contribute to the fields of ecology, evolution, and earth systems field science. In addition, active participation in courses, conferences and presentations prepare students to become effective communicators, advocates and leaders who confidently share research findings with their peers and make science more accessible to the public.


Program Curricula

Our graduate program curricula support a sound professional education encompassing factual and theoretical concepts grounded in primary research skills and training. Students may create an individualized curriculum with consultation and permission from their Research Committee and the Graduate Program Committee. Regardless of the curricula, graduate students must show knowledge of curricular subjects through oral and written examinations.


Research Areas

Graduate students can tailor their academic and career interests across our five core fields of study: ecology, evolution and systematics, biodiversity, conservation, earth and environmental science. Faculty researchers in the Department of Biodiversity, Earth and Environmental Science (BEES) take a hands-on approach when investigating past and present environmental change. Research interests range geographically from the tropics to the Arctic, from local to global scales, and from the smallest phytoplankton to enormous dinosaurs. Faculty use novel techniques and the latest equipment to explore life on Earth and the ecological processes on which life depends. Graduate students work with faculty mentors on extensive and diverse field experiences locally and internationally. Through courses, conferences, and other presentations, students learn how to make their research accessible to broad public audiences and become leading advocates for environmental issues.

Our graduate scholars have ready access to the Academy of Natural Sciences of Drexel University, which holds one of the world’s most comprehensive collections of systematics, evolutionary biology, ecology, and paleontology research. In addition, the Academy is home to the Patrick Center for Environmental Research, where scientists lead efforts to understand watershed processes and develop approaches for conserving them. The Academy’s Center for Systematic Biology and Evolution houses a natural history collection with over 19 million specimens of plants and animals. These renown collections represent a veritable library of life on Earth and are of international significance.

Ghost forest at the edge of Jakes Landing near the Dennis Creek in Cape May, New Jersey

The Future Ghost Forests of New Jersey

Jakes Landing is a centuries-old access point to Dennis Creek in Cape May, New Jersey, where the forest landscape abruptly drops into a tidal saltwater marsh. Near the marsh, row after row of dead Atlantic white cedars juts out of the ground like spikes. Just beyond those are swaths of statuesque loblolly pines that are healthy now, but these are at risk of becoming ghost forests. LeeAnn Haaf, a PhD candidate in Drexel University’s Biodiversity, Earth and Environmental Science (BEES) Department, studies the effects of climate change and sea-level rise on low-lying tree growth in the mid-Atlantic region of the United States.
