Biological & Environmental Sciences

Department of Biological and Environmental Sciences

The Department of Biological and Environmental Sciences offers programs leading to the Bachelor of Arts and the Bachelor of Science degrees, as well as a minor program for students in other disciplines who wish to fulfill a secondary interest in biology, geology, geography, environmental science, earth science, or environmental sustainability. Students interested in Earth and Environmental Sciences and Environmental Sustainability may choose from several degrees in Interdisciplinary Studies: Earth System Science concentration (B.A.), Environmental Sustainability (B.A.) or Environmental Science (B.S.). Students interested in pursuing graduate degrees in biology and careers in biological research are strongly encouraged to enroll in the Bachelor of Science program. A major in biology will automatically fulfill the requirements for admission to almost all graduate programs as well as most medical, dental, and veterinary schools.

Students can combine a major in Earth Science with a program in the College of Education, Information and Technology and earn a B.S. in Adolescence Education: Earth Science. This degree will satisfy the requirements for initial certification to teach Earth Science in grades 7 to 12. Courses in Geography are also part of the B.S. in Adolescence Education: Social Studies (Grades 7 to 12) degree. The Department also offers concentrations in Earth System Science and Geography for students pursing the B.S. in Early Childhood Education (Birth to Grade 2) and B.S. in Childhood Education (Grades 1 to 6). In addition, the Department of Earth and Environmental Science offers courses which are part of concentrations in American Studies, Social Studies and Science for these degrees.

In conjunction with the College of Education, Information and Technology, the Department of Biology offers courses which are part of the concentration in Science for the B.S. in Early Childhood Education (Birth to Grade 2) and the B.S. in Childhood Education (Grades 1 to 6).

The Department also offers minors for students in other programs wishing to pursue a secondary interest in Earth Science, Geology and Geography.

Graduate courses in Biology, Environmental Sustainability, Earth Science, Geography and Geology may be taken by undergraduate students with appropriate averages and permission.

Research opportunities are available to undergraduate students. The Department maintains an Aquatic Research Laboratory, an advanced center that is equipped with high capacity fresh and saltwater tanks, and the Miracle-Gro Greenhouse which offers the ideal environment to study plant anatomy, ecology and photosynthesis. The Campus is located close to outstanding natural resources, where students and faculty members conduct field research. Internships are available at well-known institutions such as Northwell Health, Cold Spring Harbor Laboratory and the New York Hall of Science.

Impactful Research

After more than 10 years of work dedicated to restoration of decimated bay scallop populations in the Peconic Bay, Dr. Stephen Tettelbach, along with multiple students and alumni who assisted in the project, recently published an article concluding their hypothesis and methods were successful, resulting in exponential growth of the species and significant economic impact on the fishing industry of the region.

Green is Our Favorite Color
