Lehigh’s Department of Chemical and Biomolecular Engineering offers a vibrant education and research environment with opportunities to specialize in research spanning biomolecular engineering, energy and environmental engineering, functional materials, interfacial science and engineering, and process modeling and control. All flavors of research are possible, including experiments, modeling, simulation, and theory, and combinations thereof. Comprehensive insight into all that the department has to offer in terms of both academics and research can found by visiting the department website.



In order to complete the P.C. Rossin College of Engineering Graduate Program Application, please visit RCEAS Graduate Admissions and the Graduate Application portal. Complete applications will require the following:

  • At least three (3) letters of recommendation for applicants to the Ph.D. program and at least two (2) letters of recommendation for applicants to any of the Master’s programs (submitted online by recommenders) from qualified individuals who are able to evaluate the applicant’s academic achievements and potential for graduate studies and research. Preference is given to letters from research advisors and professors (should account for at least 2 of the 3 letters for Ph.D. applicants), but relevant letters from technical/industrial employers who are able to speak to a candidate’s potential for graduate study and research will also be accepted.

  • Candidate’s resume summarizing background relevant to graduate study, including (but not limited to) education/degree(s), class rank, relevant coursework, projects, research, technical publications, relevant work experience, career goals, extracurricular activities, etc. The resume should be current, documenting experiences and positions held up to and at the time of application.

  • Candidate’s Personal Statement, detailing motivation for graduate study, relevant background and research experience, specific research interests, specific faculty of interest, etc.

  • Complete transcripts from each college and university attended. Unofficial copies may be uploaded by the candidate, but official transcripts from the prior institution’s Registrar office must be submitted by candidates who accept offers of admission. 

  • GRE scores are no longer required nor considered as part of the application review process.

  • International students: Official TOEFL or IELTS scores sent to Lehigh University by ETS (Educational Testing Service). If applicant received a degree in the United States within the past two years, these test scores can be waived. Both assessments are available for only two years from the date the test was taken.

  • Application fee of $75 (non-refundable), payable to “Lehigh University”

Ph.D. APPLICATION DEADLINE For prospective Ph.D. students seeking fall admission, full applications (including relevant test scores and letters of recommendation) should be submitted by no later than Jan. 15. Early applications are encouraged.

MASTER’S PROGRAM APPLICATION DEADLINE For prospective Master’s students seeking fall admission, full applications are preferred by Jan. 15. However, application review is carried out on a rolling basis, with decisions made year-round for matriculation in future academic semesters. International students must account for the time required for visa interview and processing when applying for a given academic semester.


All applications undergo a rigorous and holistic review, with decisions made on the basis of multiple factors beyond simple benchmarks, including the applicants motivation for advanced study, tenacious pursuit of personal and technical goals, strong or strengthening academic record, and desire and skill set to tackle challenging questions in industrial practice, the academic research lab, or even the university classroom/lab—recognizing the continuum of prior opportunities available to our applicants.

  1. Prior degrees: Applicants must have earned a Bachelor’s of Science (B.S.) or a Master of Science (M.S.) in Chemical Engineering or a related engineering discipline by the time of their matriculation. Applicants with degrees in related science fields (e.g., chemistry, physics, biology) are also welcome. Bridging coursework is available as needed to help ensure smooth transition from less conventional technical degrees into our programs.

  2. GRE scores – NO LONGER REQUIRED nor REVIEWED: Lehigh ChBE no longer requires nor evaluates GRE scores as part of the application review process, relying instead on a holistic application review.

  3. GPA benchmark: GPA (US equivalent) higher than 3.3 on a 4.0 scale for Ph.D. applicants and 3.0 on a 4.0 scale for Master’s applicants is preferred. GPA standards for international institutions will be followed accordingly. Consideration will be given to a trend showing a strengthening of the core GPA during the final semesters of study. 

  4. TOEFL or IELTS (international students only): Individual “skill section score” recommendations for Lehigh University and the Internet based TOEFL are: Writing (20), Speaking (20), Reading (20), Listening (15), Composite score (79).
    Individual “skill section score” recommendations for Lehigh University and the IELTS are: Writing (6.0), Speaking (6.5), Reading (6.5), Listening (6.0), Overall score (6.0).
