Clark University

What you'll study

The programme combines advanced coursework, original research and professional development. Early-years study typically covers foundational and advanced topics such as quantum mechanics for chemists, molecular spectroscopy, statistical mechanics, and mathematical methods for physical chemistry. More specialised modules and seminar topics reflect the optics and quantum chemistry emphasis and may include molecular and nonlinear optics, laser spectroscopy, ultrafast dynamics, quantum dynamics, electronic structure theory, and computational quantum chemistry.

Students work closely with a research advisor to develop and carry out a dissertation project that integrates experiment, theory or computation. Typical laboratory and research activities include ultrafast laser experiments, single-photon and entanglement studies, spectroscopic characterisation of novel materials, and high-level quantum chemical modelling. The programme also offers training in scientific communication, research ethics, grant writing and teaching, and encourages interdisciplinary collaborations with related groups across campus and in the regional research community.

Entry requirements

Competitive applicants normally hold a bachelor’s or master’s degree in chemistry, physics or a closely related field with solid preparation in physical chemistry, quantum mechanics and mathematics. Prior research experience—such as independent projects, publications, or laboratory internships—is strongly recommended. Applications generally require academic transcripts, a statement of purpose outlining research interests, a curriculum vitae, and at least two letters of recommendation from instructors or research supervisors. Applicants whose first language is not English must demonstrate English proficiency according to the university’s requirements.

Career prospects

Graduates with a PhD focused on optics and quantum chemistry pursue a range of careers. Many continue in academic research and teaching, taking postdoctoral positions or faculty appointments. Others move into government or national laboratory roles where expertise in spectroscopy, quantum measurement and materials characterisation is valued. Industry opportunities include positions in photonics and laser technology, quantum information and computing firms, chemical and materials companies, and R&D groups developing sensors, imaging systems or new optical materials. Graduates also work in science policy, patent law (with additional training), and technical consulting.

Why study at Clark University

Clark offers a doctoral environment characterised by small cohorts and close faculty mentoring, which supports intensive, hands-on training in specialised experimental and theoretical techniques. The chemistry department emphasises interdisciplinary research and collaboration across physics, materials science and engineering, providing students access to a range of instrumentation and computational resources. Located within reach of a larger regional science and technology ecosystem, students benefit from collaborative opportunities with neighbouring research institutions and industry partners. The programme also focuses on professional development to prepare graduates for diverse careers, including teaching experience, assistance with grant preparation and support for presenting work at conferences.
