What you'll study

The PhD emphasises a balance of advanced coursework, rigorous research methods and an independent dissertation that contributes new knowledge in applied computer science. Early in the programme students complete core graduate courses in topics such as advanced algorithms, operating systems, machine learning, and database systems, together with electives that reflect application areas.

• Core and foundation courses: theoretical foundations (algorithms, complexity), graduate-level systems (OS, distributed systems), statistics and machine learning for data-driven research.
• Advanced and elective topics: artificial intelligence and deep learning, computer vision, natural language processing, data science and big data systems, cybersecurity and privacy, networking, high-performance computing, human–computer interaction, robotics, and computational biology.
• Research methods and seminar work: requirement to attend and present in departmental seminars, reading courses, and workshops that develop research skills, reproducible experimentation and scientific communication.
• Qualifying milestones: completion of a qualifying or comprehensive examination and a dissertation proposal defence that establishes the feasibility and contribution of the planned research.
• Dissertation and defence: sustained original research under faculty supervision, culminating in a written dissertation and oral defence.

Students often combine applied research with interdisciplinary collaborations across engineering, business, health sciences and social sciences, leveraging SMU's connections in the Dallas–Fort Worth technology ecosystem.

Entry requirements

Applicants are expected to hold a strong academic record in computer science or a closely related discipline. Typical successful applicants have a relevant Bachelor’s degree (often with honours) and many hold a Master’s degree. Evidence of research potential is important.

• Academic transcripts: undergraduate and, if applicable, graduate transcripts showing strong performance in mathematics and computing courses.
• Research experience: demonstrated research potential through a Master’s thesis, research projects, publications, technical reports or significant industry R&D experience.
• Letters of recommendation: three references from academics or professional supervisors who can assess research ability and readiness for doctoral study.
• Statement of purpose: a clear description of research interests, relevant experience and fit with the department’s faculty and facilities.
• Programming and quantitative preparation: solid preparation in algorithms, data structures, probability and linear algebra; prior experience with software development and experimental methods is expected.
• English language proficiency: for international applicants, proof of English proficiency is required if prior education was not in English.

Standardised test requirements (such as the GRE) and minimum GPA expectations may vary; prospective applicants should consult the department for current admissions policies. Funding decisions and eligibility for assistantships are also part of the admissions process.

Career prospects

Graduates of the PhD in Applied Computer Science move into a wide range of research and leadership roles. Career pathways include:

• Academic careers: tenure-track faculty positions, postdoctoral research roles and teaching positions at universities and research institutes.
• Industrial R&D: research scientist and engineer roles in technology companies, telecommunications, finance, healthcare and manufacturing, focusing on applied machine learning, systems engineering, security, and data platforms.
• Technical leadership: principal engineer, research lead or CTO roles in startups and established firms, translating research into products and services.
• Government and national labs: research and technical positions addressing large-scale computing challenges and public-sector needs.
• Entrepreneurship and consulting: founding technology ventures or providing specialised consulting that leverages deep technical expertise.

Graduates benefit from SMU’s industry connections in the Dallas–Fort Worth area and from departmental support for internships, collaborations and technology transfer.
