Programme Structure and Curriculum

The Master in Computer Science and Engineering is structured around four complementary components that together total 120 ECTS credits over two years. This modular architecture gives students unusual flexibility in designing their study path while ensuring that everyone graduates with both solid foundational knowledge and deep specialisation.

The Four Pillars

The first pillar is the Core Courses component, worth 33 credits. This is dominated by the graduation project (25 credits), which is typically completed during the second year and represents the programme’s capstone research experience. The remaining 8 credits include Digital Electronic Systems (5 credits) and one of three computer science seminars (3 credits) in networking/security, software engineering, or AI/machine learning.

The second pillar is the Professional Focus, a mandatory 30-credit block that every student must complete regardless of their chosen specialisation. These five courses — Languages and Translators, Databases, Architecture and Performance of Computer Systems, Software Engineering Project, and Machine Learning: Classification and Evaluation — ensure that all graduates share a common professional competence baseline that employers expect from any computer science engineer.

The third pillar is the Options component, worth 57 credits. This is where students select one or more of the six available majors and build their specialisation. The flexibility is remarkable: students can choose a single 30-credit major and fill the remainder with cross-disciplinary electives, or combine two 20-credit majors, or even mix and match courses across multiple majors to create a truly bespoke curriculum.

A notable feature of the programme is the absence of formal prerequisites between course units. Students can take courses in either year one or year two based on their training project and schedule, which is particularly useful for students planning international exchange semesters.

The Six Specialisation Majors

UCLouvain’s six specialisation majors cover the full spectrum of modern computer science.

The Graduation Project and Research

The graduation project (LINFO2990) is the programme’s most substantial single component at 25 credits, reflecting UCLouvain’s strong research orientation. Spanning both quarters of the second year, this project requires students to conduct original research or engineering work under the supervision of a faculty member, often embedded within one of ICTEAM’s research groups.

The project can be written and presented in either English or French, providing flexibility for both international and francophone students. Topics are typically aligned with the student’s chosen major and may involve collaboration with industry partners, other research institutions, or EU-funded research projects. Past graduation projects have covered topics ranging from adversarial machine learning and privacy-preserving computation to autonomous drone navigation and quantum computing simulation.

The research environment at UCLouvain is exceptionally strong for a master’s programme. The ICTEAM institute houses research groups in computer networking (where UCLouvain researchers contributed to the development of multipath TCP), machine learning, computer vision, formal methods, and embedded systems. Students have access to state-of-the-art computing infrastructure including GPU clusters, network testbeds, and security research labs.

For students considering doctoral studies, the graduation project serves as an extended audition for PhD positions. Faculty members frequently offer doctoral positions to master’s students whose graduation projects demonstrate exceptional research potential. UCLouvain’s doctoral school is well-funded, with positions often supported by Belgian national research funds (FNRS) or EU grants.

Admission Requirements and Application

The Master in Computer Science and Engineering is classified as Level 7 in the Francophone Certification Framework, which corresponds to a second-cycle qualification in the European Higher Education Area. While the programme website details specific admission requirements by nationality and background, the general framework requires a relevant bachelor’s degree in computer science, computer engineering, or a closely related field.

Students from Belgian universities who completed the Bachelor in Engineering Sciences with a computer science or information sciences orientation (INFO or SINF) are directly admissible. International students with equivalent qualifications typically need to submit their application through the UCLouvain admissions portal, providing transcripts, degree certificates, and proof of English proficiency. Since the programme is taught entirely in English, language certification (typically TOEFL or IELTS at a level specified by the faculty) is required for non-native speakers.

Some specialisation majors have additional prerequisites. The Data Science and Applied Mathematics major requires students to have taken specific mathematics courses equivalent to a minor in mathematics. The Biomedical Engineering major requires a biomedical engineering minor from the bachelor’s level. The Cryptography option has specific requirements related to electrical engineering coursework. These prerequisites are clearly documented in the programme catalogue and should be verified before applying.

Student Life in Louvain-la-Neuve

Louvain-la-Neuve is unlike any other university city in Europe. Built in the 1970s after UCLouvain’s francophone section separated from KU Leuven, it was designed from scratch as a pedestrian-priority university town. The result is Europe’s largest car-free city centre — a place where everything revolves around student life and academic pursuits.

The city hosts approximately 30,000 students within a compact, walkable urban area. Every amenity a student needs — from supermarkets and restaurants to sports facilities and cultural venues — is within a short walk. The absence of through-traffic creates an environment that feels simultaneously urban and tranquil, with a vibrant social scene that spills across squares, terraces, and student bars.

For computer science students specifically, the Louvain-la-Neuve Science Park adds another dimension. This technology park adjacent to the campus hosts over 250 companies including tech firms, research spinoffs, and innovation hubs. Many of these companies offer internships and graduate positions to UCLouvain students, creating a direct pipeline between academic learning and professional opportunity. Companies like IBA (Ion Beam Applications) and numerous AI and cybersecurity startups maintain close ties with the ICTEAM institute.

Louvain-la-Neuve’s location is also strategically advantageous. Brussels, Belgium’s capital and the de facto capital of the European Union, is just 30 minutes away by train. This proximity provides access to EU institutions, multinational tech companies, NATO, and the enormous diplomatic and NGO community — all potential employers for computer science graduates with an interest in policy, international affairs, or institutional technology.

How UCLouvain Compares to Other Belgian CS Programmes

Belgium’s three major research universities — KU Leuven, Ghent University, and UCLouvain — each offer strong computer science programmes with different strengths and characters.

KU Leuven’s computer science programme consistently ranks highest in international league tables and benefits from a massive research infrastructure and close ties to the IMEC research centre, Europe’s leading semiconductor and nanoelectronics research hub. However, most of KU Leuven’s CS master programmes are taught in Dutch, which limits accessibility for international students who do not speak the language. The English-taught options are more limited in scope.

Ghent University offers strong CS programmes with a practical engineering orientation, particularly in areas like data science, AI, and embedded systems. Its location in a vibrant student city and its membership in research networks like IDLAB (Internet Technology and Data Science Lab) make it competitive. Like KU Leuven, however, the primary language of instruction for many programmes is Dutch.

UCLouvain’s key differentiator is its fully English-taught curriculum combined with its exceptional specialisation breadth. No other Belgian university offers six distinct CS majors within a single master’s programme. The cryptography and security specialisations benefit from UCLouvain’s internationally recognised expertise in this field — the university’s research group has contributed to the development of cryptographic standards used worldwide. The unique Louvain-la-Neuve campus environment, the proximity to Brussels, and the Louvain-la-Neuve Science Park add practical advantages that other universities cannot replicate.

For students who want a fully English-taught CS master with maximum specialisation flexibility in a research-intensive environment, UCLouvain is arguably the strongest choice in Belgium. For a broader view of European CS programmes, browse our comprehensive programme directory.
