The PhD in Astronomy and Astrophysics at Indiana University Bloomington is a research-led doctoral programme that trains students to carry out original research across observational, theoretical and instrumental astrophysics. It suits applicants with a strong physics and mathematics background who want to pursue advanced research and careers in academia, national laboratories or data-driven industries.

What you'll study

The programme combines advanced coursework, research rotations and an extended original dissertation. Early years emphasise core graduate training in astrophysics and the physical foundations of astronomy, followed by specialised coursework tailored to the student's research area.

  • Core topics: classical mechanics, electrodynamics, quantum mechanics (as relevant to astrophysics), statistical physics, radiative processes, and numerical methods.
  • Astrophysics and astronomy modules: stellar structure and evolution, galactic dynamics, high-energy astrophysics, cosmology and large-scale structure, interstellar medium and star formation, exoplanet science and planetary atmospheres, and observational techniques across the electromagnetic spectrum.
  • Computational and statistical training: computational astrophysics, scientific programming, data analysis, and modern statistical methods for large surveys and time-domain astronomy.
  • Instrumentation and laboratory coursework: optics and detector physics, radio/optical/IR instrumentation principles, and hands-on experience with instrumentation development for students working in instrument-related groups.
  • Seminar and professional skills: participation in department seminars, journal clubs, presentation skills, grant-writing and teaching practicum for those serving as teaching assistants.
  • Research and assessment: research rotations (for some students), qualifying or preliminary exams, proposal-style dissertation prospectus, and a defended doctoral dissertation based on original research supervised by faculty.

Entry requirements

Successful applicants typically hold a bachelor's or master's degree in physics, astronomy, astrophysics or a closely related quantitative discipline. Admissions emphasise strong preparation in physics and mathematics and demonstrated research potential.

  • Academic background: undergraduate- or master's-level coursework in classical mechanics, electromagnetism, quantum mechanics, statistical physics/thermodynamics, and multivariable calculus; courses in differential equations, linear algebra and numerical methods are highly recommended.
  • Research experience: prior research, such as an honours thesis, summer project or employment in an observatory, laboratory or computational group, strengthens an application.
  • Application materials: academic transcripts, curriculum vitae, a statement of purpose outlining research interests, and at least three academic/research letters of recommendation.
  • English language proficiency: international applicants whose first language is not English must meet the university's English-language requirements through approved tests or demonstrated equivalent proficiency.
  • Additional considerations: some applicants may hold a master's degree and be admitted with advanced standing; funding offers are typically linked to research or teaching assistantships and to the availability of faculty advisers with compatible research interests.

Career prospects

Graduates of the PhD programme pursue a wide range of careers that draw on their research skills, quantitative training and computational expertise.

  • Academic research and teaching: postdoctoral research positions and tenure-track faculty roles in astronomy, astrophysics and related fields.
  • National observatories and laboratories: research positions at government or national laboratory facilities involved in instrumentation, survey science and theoretical modelling.
  • Industry and technology: roles in data science, software engineering, machine learning, aerospace and instrumentation companies, where skills in large-data analysis and scientific computing are valued.
  • Science policy, outreach and education: careers in science communication, museum and planetarium work, K–12 and university teaching, and positions with scientific funding or policy organisations.

Why study at Indiana University Bloomington

Indiana University offers a research-active astronomy programme within a large public research university, providing access to interdisciplinary collaborations across physics, earth and atmospheric sciences, and computer science. The department supports both observational and theoretical research areas and encourages student involvement in instrumentation projects and large survey science.

  • Research infrastructure: students benefit from campus computing resources and partnerships that support numerical simulations and large-scale data analysis, as well as opportunities to work with national and international observatories through faculty collaborations.
  • Graduate community and mentoring: a collegial graduate population, structured advising and teaching experience prepare students for research and professional development.
  • Interdisciplinary opportunities: proximity to complementary research groups on campus facilitates collaborations in planetary science, computational methods and instrumentation engineering.
  • Funding and training: doctoral students are typically supported through a combination of research assistantships, teaching assistantships and fellowship opportunities, which provide stipends and tuition support while students focus on research and professional growth.
