The PhD in Chemistry (with emphasis in Optics and Quantum Chemistry) at Johns Hopkins University is a research-focused doctorate training students to tackle fundamental and applied problems in light–matter interactions, quantum dynamics and quantum-enabled materials. It suits students with strong backgrounds in chemistry, physics or materials science who want intensive laboratory and theoretical training leading to independent research careers in academia, national labs or industry.
What you'll study
The PhD programme combines advanced coursework, laboratory rotations and sustained original research centred on optics, photonics and quantum chemical theory. Early-stage study typically includes core courses in quantum mechanics for chemists, electronic structure methods, statistical mechanics and advanced spectroscopy, followed by specialist modules such as ultrafast and nonlinear optics, quantum dynamics, many-body theory, and computational photochemistry.
- Coursework: Advanced Quantum Mechanics; Electronic Structure Theory and Methods; Spectroscopic Methods in Chemistry; Statistical Thermodynamics; Solid State Chemistry and Materials for Photonics.
- Specialist topics: Ultrafast Spectroscopy and Dynamics; Nonlinear Optics; Quantum Information Concepts for Chemistry; Light–Matter Interaction in Nanoscale Systems; Open Quantum Systems and Decoherence.
- Practical training: laboratory rotations in research groups working on experimental optics, ultrafast measurements, nanophotonics, or theoretical/computational quantum chemistry; hands-on training in instrumentation, pulse-shaping, single-photon detection and high-performance computing.
- Research milestones: qualifying/advancement to candidacy exam, proposal and dissertation research, regular seminar presentations and a final public defence.
- Additional components: departmental seminars, journal clubs, opportunities for teaching or mentoring undergraduates, and training in research ethics and scientific communication.
Entry requirements
Applicants are expected to hold a strong undergraduate degree in chemistry, physics, materials science or a closely related discipline. Prior research experience in experimental or theoretical physical chemistry, optics, photonics or quantum physics is highly desirable.
- Academic transcripts: evidence of strong preparation in quantum mechanics, physical chemistry and mathematics.
- Research experience: laboratory or computational project work, publications or extended undergraduate/masters research are advantageous.
- Supporting documents: a curriculum vitae, a statement of research interests describing fit with faculty groups, and at least three academic references.
- Language proficiency: applicants whose first language is not English must meet the university's English-language requirements.
- Other requirements: applicants should consult the Department of Chemistry for current information on tests or additional materials (for example, departmental interviews or portfolio samples) and for specific advice about faculty with complementary research programmes.
Career prospects
Graduates from this programme move into a wide range of research-driven careers. Common pathways include tenure-track or research faculty positions, postdoctoral research in optics/quantum science, scientific leadership roles in national laboratories, and research and development positions in industry sectors such as quantum computing, photonics, optical communications, sensors and materials. Graduates also work in adjacent fields—device engineering, computational chemistry, chemical physics, and technology start-ups—where expertise in light–matter interactions and quantum theory is in demand.
Why study at Johns Hopkins University
