Engineering Modified with Environmental Sciences

Students interested in environmental engineering may pursue the engineering sciences major modified with environmental sciences. Students who plan to pursue additional coursework beyond the AB to earn the Bachelor of Engineering (BE) should consult early with their faculty advisors to plan their program of study.

For additional information about majors, courses, and degree requirements:

Guide to Programs & Courses

For advice about the major, contact Professor Benoit Cushman-Roisi or Professor Lee Lynd.


Modified majors are expected to have a basic understanding of calculus, physics, chemistry, and computer science. First-year students interested in the major should take the placement test in mathematics.

Unless otherwise prohibited, prerequisites may be taken under the non-recording option. Any course being used to satisfy major or minor requirements beyond the prerequisites, may not be taken under the non-recording option.



3 courses

MATH 3: Calculus
MATH 8: Calculus of Functions of One and Several Variables
MATH 13: Calculus of Vector-Valued Functions


2 courses

PHYS 13: Introductory Physics I

1 course

Students will be placed in one of the following:

CHEM 5: General Chemistry
CHEM 10: First-Year Honors Chemistry
CHEM 11: General Chemistry

Computer Science

1 or 2 courses

Choose one option:

Option 1 (1 course):
ENGS 20: Introduction to Scientific Computing (May not be taken under the non-recording option.)

Option 2 (2 courses):
COSC 1: Introduction to Programming and Computation
COSC 10: Problem Solving via Object-Oriented Programming


1 course

BIOL 16: Ecology (This requirement may change during the 2022-2023 academic year. Please discuss with your advisor when you declare.)

* Students with no prior experience with chemistry will be placed in CHEM 5. CHEM 10 is not scheduled to be offered during the 2022–2023 academic year. Starting in the Fall of 2022, students with prior experience with chemistry (as demonstrated through AP or IB exams, A-level credit, or placement exam) will be placed in CHEM 11. Students who complete CHEM 11 will also automatically receive credit for CHEM 5 toward the BE degree requirements.
