Program description
Degree awarded: PHD  Environmental Engineering

The Doctor of Philosophy program in environmental engineering prepares students to conduct original, use-inspired research that advances the field and addresses society's most pressing environmental challenges. Students work with leading faculty to develop specialized expertise in areas such as water and wastewater treatment, air quality management, pollution control and sustainable infrastructure.

Through advanced coursework and extensive research experience, students gain deep technical knowledge and proficiency in environmental chemistry, microbiology, data analytics and systems modeling. The program emphasizes innovation, interdisciplinary collaboration and the use of emerging technologies to design resilient, sustainable solutions that protect human and ecosystem health.

Graduates of the program are prepared for leadership roles in academia, industry, government and nongovernmental organizations, where they advance research and solutions of public value.

Program term definitions

Accelerated programs allow students the opportunity to expedite the completion of their degree.

Accelerated master's

These programs allow students to accelerate their studies to earn a bachelor's plus a master's degree in as few as five years (for some programs).

Each program has requirements students must meet to be eligible for consideration. Students typically receive approval to pursue the accelerated master's during the junior year of their bachelor's degree program. Interested students can learn about eligibility requirements and how to apply.

Concurrent degrees allow students to pursue their own personal or professional interests, earn two distinct degrees and receive two diplomas. To add a concurrent degree to your existing degree, work with your academic advisor.

Joint programs, or jointly conferred degrees, are offered by more than one college and provide opportunities for students to take advantage of the academic strengths of two academic units. Upon graduation, students are awarded one degree and one diploma conferred by two colleges.

ASU adds new programs to Degree Search frequently. Come back often and look for the "New Programs" option.

ASU Online offers programs in an entirely online format with multiple enrollment sessions throughout the year. See https://asuonline.asu.edu/ for more information.

The Western Regional Graduate Program (WRGP) provides a reduced tuition rate to non-resident graduate students who qualify. Visit the WRGP/WICHE webpage for more information: https://graduate.asu.edu/wiche.
