The PhD in Astronomy and Astrophysics at the University of Hawaii at Manoa is a research-led doctorate that trains students in observational, theoretical and instrumental approaches to modern astrophysics. It suits applicants with a strong background in physics or astronomy who want to undertake original research using world-class facilities and collaborations based at the Institute for Astronomy and associated observatories.

What you'll study

The programme combines advanced coursework with an extended research project leading to a doctoral dissertation. Early years typically include core courses in stellar astrophysics, galactic and extragalactic astronomy, cosmology, radiative processes, and statistical and computational methods. Students also take specialised modules in observational techniques (optical, infrared, millimetre, and radio), high-energy astrophysics, planetary science and instrumentation depending on their research focus.

  • Core topics: stellar structure and evolution, galaxy formation and evolution, cosmology, radiative transfer and spectroscopy, dynamics and N-body methods.
  • Techniques and tools: observational methods, telescope and detector instrumentation, data reduction and analysis, high-performance computing, and statistical inference for astronomy.
  • Research training: proposal writing, research ethics, seminars, and participation in group meetings and collaborations.
  • Structure: coursework and qualifying examinations in the first one to two years, followed by focused research under supervision, publication of results in peer-reviewed journals, and a final thesis defence.

Entry requirements

Applicants are expected to hold a relevant undergraduate or master's degree in physics, astronomy, astrophysics or a closely related field, with strong preparation in classical mechanics, electromagnetism, quantum mechanics and mathematics (calculus, differential equations, linear algebra). Demonstrated research experience — such as a senior thesis, summer research placement or publications — is highly desirable.

  • Academic transcripts showing strong performance in core science and mathematics courses.
  • Letters of recommendation from academic or research supervisors that address research potential.
  • A statement of purpose outlining research interests and potential fit with faculty expertise and facilities.
  • Evidence of numerical and programming competence (e.g. Python, C/C++, IDL, or equivalent) is often expected.
  • International applicants must meet English language requirements; specifics are set by the university.

Career prospects

Graduates of the PhD in Astronomy and Astrophysics pursue research and technical careers across academia, national observatories and research institutes, and the wider space and technology sectors. Typical career paths include:

  • Postdoctoral research positions at universities and national laboratories focusing on observational, theoretical or instrumental projects.
  • Staff scientist or instrument scientist roles at major observatories and telescope facilities.
  • Research and engineering roles in the space and aerospace industries, including mission science and payload development.
  • Data science, software engineering and analytics positions in industry where advanced quantitative and computing skills are valued.
  • Science communication, policy or education roles leveraging specialist knowledge in astrophysics.

Why study at University of Hawaii at Manoa

The University of Hawaii at Manoa hosts the Institute for Astronomy (IfA), providing exceptional proximity to world-class observing facilities and long-standing international collaborations. Graduate students benefit from direct access to Maunakea and Haleakala observatories, involvement with large survey projects and instrument development, and opportunities to work with faculty whose research spans observational, theoretical and instrumental astrophysics.

Beyond facilities, the programme offers a collegial research environment with interdisciplinary links across planetary science, atmospheric physics and computational science, as well as professional development through seminars, collaborations and teaching experience. The university's location also provides a unique cultural and environmental setting that many students find enriching for both study and research.
