Chemical Engineering (PHD) 
Program Description

The Chemical Engineering Program is designed to provide advanced work in a core of transport phenomena, thermodynamics and reaction engineering.

Students conduct research on a diverse range of projects due to multidisciplinary strengths, including nanotechnology, drug delivery, cancer detection/treatment, renewable energy, clean semiconductor manufacturing, water treatment and reuse, atmospheric chemistry and physics, life cycle assessment, electrochemistry, and applied quantum chemistry. There are especially strong interdisciplinary links to the Environmental Engineering Program, which has long-standing strengths in water and wastewater treatment science and technology as well as technology transfer, hazardous waste treatment, development of environmentally-friendly technologies for industry, and air quality research. This department’s environmental research contributes to the UA being one of the top ranked world programs in environmental science research.

Departmental research takes advantage of state-of-the-art facilities such as the Water & Energy Sustainable Technology (WEST) Center (, the BIO5 Institute (, the Micro/Nano Fabrication Center (, and various facilities associated with the Institute for Energy Solutions (

Students in this program have a good track record of receiving financial aid from both university and federal fellowships. Graduates of this program most commonly obtain jobs in industry, government organizations, consulting, and continue on to academia.

Admissions Information

Admissions Requirements

These items must be sent through the Graduate College online application.

  • Graduate College Application for either domestic or international students
  • Application processing fee: $85 for degree-seeking domestic students, $95 for international students and $45 for non-degree-seeking students
  • Three letters of recommendation
  • Resume
  • Statement of purpose
  • Official scores from TOEFL, IELTS, PTE or CEFR exam (required for international students only; university code is 4832, chemical engineering code is 1001; environmental engineering code is 1103)
  • Official scores from the GRE (required for all applicants, both domestic and international; university code is 4832, chemical engineering code is 1001, environmental engineering code is 1103); scores above the 90th percentile are recommended for the analytical and quantitative sections
  • Unofficial electronic copies of transcripts from previous academic work

Test Scores: 
The institution code for the University of Arizona is 4832, which you chose when you register for tests like the TOEFL or GRE. Results are sent electronically to the university, typically within two weeks of the test date. After your application is submitted, our search/match system will attempt daily to match your test scores to your GradApp record. Please make sure the name on your tests matches the name on the application to avoid missing scores. The department code is helpful but not necessary.

English Proficiency:
English proficiency is required for all applicants whose native language is not English. Applicants must submit a minimum Test of English as a Foreign Language (TOEFL) score of 60 on the revised paper-based (PB) (550 on PBT taken before 2017) or 79 internet-based (iBT); an International English Language Testing System (IELTS) composite score of 7 or better, with no subject area score below a 6; a Pearson PTE Academic (PTE) score of 60 or better; or a Common European Framework of Reference for Languages (CEFR) score of level C1 or better. Individual departments may require a higher score and have minimum score requirements by test module.

Admissions Deadlines

Domestic Applicants:

  • Fall: January 15
  • Spring: June 30

International Applicants:

  • Fall: January 15
  • Spring: June 30

Note to applicants: In order to receive priority consideration for fall admission and full consideration for department funding, fall applicants are strongly encouraged to submit their completed applications by December 15. The final deadline for fall applications is January 15. Final deadline for spring applications is June 30. Most of our PhD students start in the fall; spring admission is rare and less likely to secure funding.

International Conditional Admission
International applicants will not be considered for conditional admission by this program.
