First-Year Exploration

Currently enrolled Harvard College students are encouraged to explore their potential interests in Environmental Science and Engineering by meeting with Bryan Yoon (Assistant Director of Undergraduate Studies, Environmental Science and Engineering).

The sample schedules below show a typical path through the first two-years for a preconcentrator interested in ESE.  These sample schedules are provided as a guiding example, and students may decide on an alternate path. We strongly recommend that students interested in any of the engineering areas begin taking mathematics in their first semester and plan to complete their math, chemistry, and physics requirements within the first two years.  Leading up to a declaration of the Environmental Science & Engineering Track during the sophomore year, students will work with concentration advisers to construct an individual degree program that matches their specific interests within ESE while simultaneously fulfilling all of the concentration requirements.

Once ESE students have established a foundation in the prerequisite math and science courses, they can take many exciting upper-level electives. While these courses are typically taken in the junior and senior years, some students with advanced preparation in math and science begin taking the 100-level courses during their sophomore year.  Upper-level ESE courses focus on the fundamental processes governing environmental systems and human impacts on those systems, such as the principles governing the movement of water in the earth’s subsurface (ESE 162), oceans (ESE 131), and atmosphere (ESE 129); the chemical behavior of pollutants in the aqueous (ESE 164) and atmospheric (ESE 133) compartments of the environment; the transport and control of pollution in natural waters (ESE 163); the parallels in ecosystem processes in both natural and urban environments (ESE 115) and the earth resources for both conventional and renewable energy (ESE 109).

Tips for ESE students:

  • Take ESE 6 in your first semester if your math placement is 1B or higher. If not, you can take ESE6 in your sophomore Fall. 
  • PS 11 is required for both AB and SB students.
  • Most of our graduating seniors recommend AM10 over CS50.
