Program Overview: Master of Science in Data Science at Harvard
The Data Science master's program at Harvard University combines computer science and statistics to train students how to analyze, contextualize, and draw insights from vast amounts of data. Jointly led by the Computer Science and Statistics faculties within the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), this program sits at the intersection of statistical methodology, computational science, and a wide range of application domains.
The program offers strong preparation in statistical modeling, machine learning, optimization, management and analysis of massive data sets, and data acquisition. It also focuses on topics such as reproducible data analysis, collaborative problem solving, visualization and communication, and the security and ethical issues that arise in data science.
Students complete 12 courses over a minimum of three semesters on campus, with the option to extend to a fourth semester for additional coursework or to complete a master's thesis research project. The program emphasizes hands-on research projects and culminates in either a capstone project with real-world industry partners or a faculty-supervised thesis.
Key Program Highlights
- Jointly led by Harvard's Computer Science and Statistics faculties, blending two rigorous disciplines into one interdisciplinary degree.
- Capstone projects with industry partners such as Spotify and the Massachusetts Bay Transportation Authority provide real-world experience.
- Cross-registration with MIT is available, giving students access to graduate-level courses at one of the top technical institutions in the world.
- STEM-designated program, allowing international graduates to benefit from extended Optional Practical Training (OPT) in the United States.
Curriculum and Course Structure
The S.M. in Data Science requires successful completion of 48 credits across 12 letter-graded courses. The curriculum is designed around eleven learning outcomes developed collaboratively by the computer science and statistics faculty, covering everything from statistical modeling to ethical data use. Students are expected to take as many 200/2000-level SEAS courses as possible, ensuring advanced graduate-level rigor.
Data Science I (AC 209a)
4 CreditsAn introduction to data science covering data wrangling, exploratory analysis, statistical learning, and prediction using real-world messy data sets. Students build foundational skills in Python-based data analysis and machine learning methods.
Data Science II (AC 209b)
4 CreditsThe continuation of Data Science I, this course deepens skills in advanced statistical and machine learning methods. Topics include deep learning, Bayesian modeling, and advanced optimization techniques applied to complex data problems.
Statistics and Probability
4 CreditsA rigorous course in statistical inference and probability theory providing the mathematical foundations essential for data science. Students develop skills in hypothesis testing, regression analysis, and probabilistic modeling.
Machine Learning and AI
4 CreditsCovers core machine learning algorithms, including supervised and unsupervised learning, neural networks, and reinforcement learning. Emphasis is placed on both theoretical understanding and practical implementation.
Data Ethics and Critical Thinking (AC 221)
4 CreditsExamines the wide-ranging impact of data science on society, focusing on fairness, privacy, ethics, and bias in algorithms and predictive models. Case studies span media, tech, public health, and politics.
Capstone Project (AC 297r)
4 CreditsA collaborative course where teams of 3-4 students work on real-world projects sourced from industry partners. Students develop novel solutions while applying skills from core courses and electives, preparing them for professional data science work.
