What will I learn?

Students entering the AES PhD program will come from a range of science backgrounds, but will share a common interest in studying and discovering the interactions between earth processes and humans. This common interest will be built upon by enrollment in some common courses and in a concentration area within the program.

The Ph.D. program prepares students for academic positions or research and leadership positions in local, state, national, or private environmental organizations. The goal of the program is to prepare future researchers and leaders who assess complex environmental systems and assist in providing sound options and solutions for optimizing human-environment interactions.

Research specialization at the PhD level is supported by concentrations, which provide students with adequate technical expertise to excel in research and to be able to apply defined skills to a wide range of problems in applied earth sciences.

What will you learn?
Course Concentration

Research specialization at the Ph.D. level is supported by concentrations in water resources, geochemical processes, and physical Earth, which provide students with adequate technical expertise to excel in research and to be able to apply defined skills to a wide range of problems in applied earth sciences. Students must identify their course concentration cluster by the second semester of enrollment in the Ph.D. program. Students will take courses within their cluster, with guidance from their research advisor and research committee, and one course from each of the other clusters. Students must complete a minimum of nine credit hours of coursework in the IUPUI ES department from among the course topics below.
