The doctoral program in astrophysical sciences and technology focuses on the underlying physics of phenomena beyond the Earth and on the development of the technologies, instruments, data analysis, and modeling techniques that will enable the next major strides in the field.
There has never been a more exciting time to study the universe beyond the confines of the Earth. A new generation of advanced ground-based and space-borne telescopes and enormous increases in computing power are enabling a golden age of astrophysics. The doctoral program in astrophysical sciences and technology focuses on the underlying physics of phenomena beyond the Earth and on the development of the technologies, instruments, data analysis, and modeling techniques that will enable the next major strides in the field. The program's multidisciplinary emphasis sets it apart from conventional astrophysics graduate programs at traditional research universities.
The program offers tracks in astrophysics (including observational and theoretical astrophysics), computational and gravitational astrophysics (including numerical relativity, gravitational wave astronomy), and astronomical technology (including detector and instrumentation research and development). Students can pursue research interests in a wide range of topics, including design and development of novel detectors, multiwavelength studies of proto-stars, active galactic nuclei and galaxy clusters, gravitational wave data analysis, and theoretical and computational modeling of astrophysical systems including galaxies and compact objects such as binary black holes. Depending on research interests, students may participate in one of three research centers: the Center for Computational Relativity and Gravitation (Video), the Center for Detectors, or the Laboratory for Multi-wavelength Astrophysics.
In the astrophysics Ph.D., students complete a minimum of 60 credit hours of study, consisting of at least 24 credit hours of course work and at least 24 credit hours of research. Students may choose to follow one of three tracks: astrophysics, astroinformatics and computational astrophysics (with the option of a concentration in general relativity), or astronomical instrumentation. All students must complete four core courses with grades of B or better, as well as two semesters of a graduate seminar. Core course grades below B must be remediated by taking and passing a comprehensive exam on the core course subject matter prior to receiving the doctoral degree. The remaining course credits are made up from specialty track courses and electives. Students must pass a qualifying examination, which consists of completing and defending a master's-level research project, prior to embarking on the dissertation research project.
Electives include additional courses in astrophysics and a wide selection of courses offered in other RIT graduate programs (e.g., imaging science, computer science, engineering), including detector development, digital image processing, computational techniques, optics, and entrepreneurship, among others.
During the first year of the program, most doctoral candidates begin a master's-level research project under the guidance of a faculty member. The project gains momentum during the second year after the core courses have been completed. The master's-level research topic may be different from the eventual doctoral dissertation topic, and the supervising faculty member will not necessarily serve as the dissertation research advisor.
The doctoral qualification requirements consist of a combination of a publication-quality master's-level project report, which may be in the form of a thesis (if the student so chooses) and an oral presentation and defense of the master's-level project. This qualification process, which must be completed by the beginning of the third year of full-time study or its equivalent, is designed to ensure the student has the necessary background knowledge and intellectual skills to carry out doctoral-level research in the subject areas of astrophysical sciences and technology. A director-approved committee consisting of the student's master's-level project research advisor and two additional faculty members will assess the student's project report and defense.
After passing the qualifying examination, students are guided by a dissertation research advisor who is approved by the program director. The choice of advisor is based on the student's research interests, faculty research interests, and available research funding.
After passing the qualifying examination, a dissertation committee is appointed for the duration of the student's tenure in the program. The committee chair is appointed by the dean of graduate education and must be a faculty member in a program other than astrophysical sciences and technology. The committee chair acts as the institutional representative in the final dissertation examination. The committee comprises at least four members and in addition to the chair, must also include the student's dissertation research advisor and at least one other member of the program's faculty. The fourth member may be an RIT faculty member, a professional affiliated in industry, or a representative from another institution. The program director must approve committee members who are not RIT faculty.
Within six months of the appointment of the dissertation committee, students must prepare a Ph.D. research project proposal and present it to the committee for review. The student provides a written research proposal and gives an oral presentation to the committee, who provides constructive feedback on the project plan. The review must take place at least six months prior to the dissertation defense.
Each fall, students provide an annual report in the form of an oral presentation, which summarizes progress made during the preceding year. The program director also monitors student's progress toward meeting the requirements for either the qualifying examination (during the first two years), or the Ph.D. (after passing the qualifying examination). Students may be interviewed, as necessary, to explore any concerns that emerge during the review and to discuss remedial actions.
Once the dissertation is written, distributed to the dissertation committee, and the committee agrees to administer the final examination, the doctoral candidate may schedule the final examination. The candidate must distribute a copy of the dissertation to the committee and make the dissertation available to interested faculty at least four weeks prior to the dissertation defense.
The final examination of the dissertation is open to the public and is primarily a defense of the dissertation research. The examination consists of an oral presentation by the student, followed by questions from the audience. The dissertation committee privately questions the candidate following the presentation. The dissertation committee caucuses immediately following the examination and thereafter notifies the candidate and the program director of the results.
All students in the program must spend at least one year (summer term excluded) in residence as full-time students to be eligible to receive the doctorate degree.
All doctoral candidates must maintain continuous enrollment during the research phase of the program. Normally, full-time students complete the course of study in approximately four to five years. A total of seven years is allowed to complete the requirements after first attempting the qualifying examination.

The astrophysical sciences and technology program offers students a wide range of research opportunities spanning observational and theoretical astrophysics, computational astrophysics, general relativity and gravitational wave astronomy, and the design and development of advanced detectors and instrumentation for astronomy. RIT hosts a vibrant astronomy and astrophysics research community of more than 60 faculty, post-docs, research fellows, and graduate students who participate in three designated research centers:
Faculty and students frequently obtain data from space observatories including the Hubble Space Telescope, the Spitzer Space Telescope, the Chandra X-ray Observatory, the Herschel Space Observatory, and various ground-based observatories such as the Gemini Observatory, twin 8.1-meter diameter optical/infrared telescopes located in Hawaii and Chile, the W. M. Keck Observatory on Hawaii, and the Very Large Array radio telescope facility in New Mexico. RIT is a member of the LIGO Scientific Collaboration, which analyzes the data taken by the Laser Interferometer Gravitational-Wave Observatory, and a member of the Legacy Survey of Space Time Corporation, which will operate an 8.4 m telescope at the Vera C. Rubin Observatory in Chile, to conduct a 10-year survey of the Southern skies.
Computing facilities include the GravitySimulator supercomputer, dedicated to N-body simulations of galactic nuclei and stellar clusters and the NewHorizons computer cluster, for numerical relativity and relativistic hydrodynamics simulations. Funding has recently been obtained to acquire an even more powerful 600-core cluster (BlueSky). Researchers at RIT's Center for Computational Relativity and Gravitation also have access to national supercomputing facilities, such as the Blue Waters supercomputer at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
RIT's Center for Detectors operates four research laboratories: the Rochester Imaging Detector Laboratory, the Imaging LIDAR Laboratory, the Quantum Dot Detector Laboratory, and the Wafer Probe Station Laboratory. The lab also has access to state-of-the-art machining and electronic assembly facilities on campus and advanced simulation software.
Faculty involved in the astrophysical sciences and technology program regularly attract substantial external research funding from national and state agencies, including funding support from SA, National Science Foundation, NYSTAR (Empire State Development Division of Science, Technology, and Innovation), amounting to over $12 million in the last four years.
