What you'll study

The PhD in Data Science combines advanced coursework, interdisciplinary research and a substantial original dissertation. Core study areas typically include statistical learning and inference, machine learning, optimization, algorithms for large-scale data, data management and databases, distributed and high-performance computing, and ethical and privacy-aware data practices.

Typical programme structure comprises:

• Foundational coursework in probability, statistics, linear algebra and advanced computing for data-intensive problems.
• Advanced modules such as deep learning, probabilistic graphical models, time-series analysis, causal inference, natural language processing, computer vision, and scalable machine learning systems.
• Practical seminars and lab rotations that provide hands-on experience with large datasets, cloud and HPC environments, and industry-relevant toolchains.
• Research components including a qualifying examination or portfolio, candidacy milestone, and an original dissertation that contributes new methods, theory or applications in computational and data science and engineering.
• Opportunities for interdisciplinary collaboration across departments (for example, engineering, computer science, statistics, business, and social sciences) and for applied projects with local industry and research partners.

Entry requirements

Successful applicants normally hold a strong quantitative bachelor’s degree or a relevant master’s degree in computer science, statistics, mathematics, engineering, or another related discipline. A solid background in calculus, linear algebra, probability and statistics, and programming experience (Python, R, or similar) are expected.

• A competitive undergraduate or graduate academic record demonstrated by transcripts.
• Evidence of research potential, typically through a research statement, publications, master’s thesis, or significant project work.
• Letters of recommendation from academic or professional referees who can speak to the applicant’s quantitative aptitude and research promise.
• A personal statement outlining research interests and alignment with faculty expertise; some applicants supply a writing or coding sample or brief research proposal.
• Standardised test requirements (such as the GRE) and English language proficiency evidence for international applicants vary; check the department’s admissions page for current policy.

Career prospects

Graduates of a PhD in Data Science pursue a range of careers in both academia and industry. Common paths include:

• Academic positions and postdoctoral research in departments of computer science, statistics, data science and related fields.
• Research scientist or R&D roles in technology companies, start-ups, and research labs, working on core machine learning methods, systems for large-scale data, and applied AI.
• Data science and engineering leadership roles in finance, healthcare, energy, telecommunications and government agencies that require advanced modelling and scalable solution design.
• Consulting and entrepreneurship, where deep technical expertise supports product development or data-driven services.
