What you'll study

This PhD pathway emphasises advanced study and original research at the interface of optics, quantum chemistry and materials science. You will combine coursework, seminars and intensive laboratory or computational research leading to a doctoral dissertation. Program topics typically include:

• Quantum chemistry and electronic structure theory: many-body methods, ab initio and density functional theory approaches, excited-state methods, and model Hamiltonians for correlated systems.
• Optical spectroscopy and photophysics: ultrafast spectroscopy, nonlinear optics, single-molecule and ensemble spectroscopies, and techniques for probing light–matter coupling.
• Photonic and quantum materials: design and characterisation of organic/inorganic semiconductors, 2D materials, nanostructures, and materials for quantum information or sensing.
• Theory–experiment integration: time-dependent quantum dynamics, quantum optics, cavity quantum electrodynamics, and methods for simulating coupled light–matter systems.
• Advanced methods and instrumentation: experimental instrument design, ultrafast pulse shaping, cryogenic/low-temperature techniques, and high-performance computing for quantum simulations.

Programme structure generally includes a combination of foundational and specialised graduate courses in physical chemistry, quantum mechanics and optics, as well as interdisciplinary electives from physics, materials science and electrical engineering. Students undertake original research under the supervision of a faculty advisor, pass qualifying and proposal examinations, and complete a written and oral dissertation defence. Many students also gain teaching experience through graduate teaching assistantships.

Entry requirements

Applicants should hold a relevant undergraduate or master’s degree in chemistry, physics, materials science, electrical engineering or a closely related field. A strong academic record with evidence of mathematical and physical foundations is expected, including coursework in quantum mechanics, physical chemistry or optics, and advanced mathematics.

• Academic transcripts: degree transcripts demonstrating preparation for graduate-level research.
• Research experience: prior undergraduate or postgraduate research, publications or substantial laboratory/computational projects are highly desirable.
• References: at least two or three letters of recommendation from faculty or research supervisors who can speak to research potential.
• Statement of purpose: a clear research statement indicating interest in optics and quantum chemistry and potential faculty collaborators.
• Additional materials: some applicants may submit a curriculum vitae/CV and examples of written work. Standardised tests are considered according to institutional policy; consult the programme admissions page for current requirements.

Career prospects

Graduates from this field combine deep theoretical understanding with hands-on experimental or computational skills valued across academia and industry. Typical career paths include:

• Academic research and teaching: tenure-track or research faculty positions in chemistry, physics and engineering departments.
• Industry R&D: roles in photonics, quantum computing and communications, optoelectronics, materials development, and chemical companies developing light-driven processes or sensors.
• National and government laboratories: research scientist positions addressing advanced spectroscopy, quantum materials and national security technologies.
• Technology translation and startups: technical leadership in spinouts or startups commercialising photonic devices, quantum sensors or materials innovations.
• Computational and data-driven roles: positions requiring expertise in electronic structure, modelling and high-performance computing applied to materials and device design.

Why study at Georgia Institute of Technology

Georgia Tech offers an interdisciplinary environment that is particularly well suited to optics and quantum chemistry.
