Master's in Data Science

2 Years On Campus Masters Program

Johns Hopkins University

Program Overview

The Master's in Data Science at Johns Hopkins University prepares students to transform complex datasets into meaningful insights through advanced statistical methods, computational techniques, and machine learning. Designed for students interested in careers across technology, healthcare, finance, scientific research, and business analytics, the programme combines theoretical foundations with practical learning, research opportunities, and industry-focused projects.

Curriculum Structure

The programme generally takes three to four full-time semesters, with students following either a course-only option or a research-focused capstone option. The curriculum is organised around four core areas: Statistics, Computing, Optimization, and Machine Learning. Students select courses from these areas alongside electives according to their academic interests and career objectives.

Year 1: Foundations and Core Specialisation

During the first semester, students establish their foundation through Introduction to Data Science (EN.553.636) or Machine Learning (EN.601.675). They also begin developing expertise across the core areas, with courses such as Applied Statistics and Data Analysis (EN.553.613) and Algorithms for Data Science (EN.685.621), covering statistical techniques, computational methods, and data-driven problem-solving.

In the second semester, students deepen their knowledge through advanced core subjects and electives. Relevant modules include Bayesian Statistics (EN.553.632), Optimization in Data Science (EN.553.662), and Deep Learning (EN.520.638), helping students understand predictive modelling, optimisation techniques, and advanced machine learning applications.

Year 2: Advanced Electives and Applied Research

In the second year, students complete their remaining elective requirements and, if they choose the research-focused capstone option, undertake the Data Science Capstone Experience (EN.553.806). This six-credit research project allows students to investigate a data science problem under the guidance of a Johns Hopkins faculty supervisor, develop their findings, and present their work through a research poster and final report. Students choosing the course-only option instead complete their remaining core and elective courses without the capstone requirement.

Focus Areas

Computer Vision, Computational Medicine, Language and Speech Processing, Natural Language Processing, Mathematical Finance, Mathematics of Data Science, Machine Learning, Statistical Analysis, Big Data and Computing, Optimization.

Learning Outcomes

Students develop the ability to analyse complex datasets, apply statistical modelling and machine learning techniques, design efficient algorithms, implement computational and optimisation methods, interpret data-driven results, solve practical problems through advanced analytics, conduct independent research, and communicate technical findings through research reports and presentations.
