University of Arizona

What you'll study

This programme is interdisciplinary and research-focused, allowing students to construct a programme of study that draws on faculty and resources across the university’s natural science departments. Typical study combines core methods and theory with elective units and a supervised research project or thesis. Core topics available include ecology and evolution, molecular and cellular biology, analytical and synthetic chemistry, environmental and hydrological science, planetary and atmospheric science, and computational modelling and data analysis.

• Research project / thesis: an extended individual research project supervised by faculty, conducted in a laboratory, field site or computational environment.
• Research methods and statistics: courses in experimental design, quantitative analysis, geospatial methods, or bioinformatics, depending on emphasis.
• Discipline-specific options: advanced molecular biology techniques, organic and inorganic synthesis, planetary geology, climate science, or ecological field techniques.
• Seminars and professional skills: scientific communication, grant writing, ethics, and career preparation modules.

Students typically work closely with a faculty advisor to select coursework and to propose and carry out a research thesis. The programme supports laboratory, field-based and computational projects and encourages collaboration with research centres such as Biosphere 2, the BIO5 Institute and the School of Earth and Space Exploration.

Entry requirements

Applicants are expected to hold a bachelor’s degree in a relevant scientific discipline (for example biology, chemistry, physics, earth sciences, environmental science or a closely related field) from an accredited institution. Admissions decisions are based on academic record, the fit between applicant interests and faculty expertise, and research potential.

• Academic transcript: evidence of undergraduate coursework in core scientific subjects and quantitative methods.
• References: typically two or three academic or professional references that can speak to research potential and academic preparation.
• Personal statement / statement of purpose: a description of research interests, career goals and how the programme and potential supervisors match those plans.
• CV / résumé: summary of academic, research and relevant professional experience.
• English language proficiency: international applicants must provide proof of English language ability where required by university policy.

Some applicants may be invited to contact potential supervisors before applying. Specific documentation requirements and any standardised test policies are set by the university and can vary by department; applicants should consult the programme admissions page for full, current instructions.

Career prospects

Graduates of the Master’s in Natural Sciences follow a wide range of career paths because of the programme’s interdisciplinary and research-orientated nature. Common directions include:

• Research and laboratory roles: research technician, laboratory manager, or project scientist in academia, government laboratories or the private sector.
• Environmental and natural resource sectors: environmental consultant, field ecologist, water resource analyst or conservation scientist with NGOs, consultancies or public agencies.
• Industry and applied science: roles in biotechnology, pharmaceuticals, materials science, energy and environmental technology companies.
• Data-driven roles: applied data science, geospatial analysis and modelling positions where quantitative and computational skills are required.
• Further study: many graduates use the Master’s as a stepping stone to PhD study and careers in academic research or university teaching.
