Programme Structure and ECTS Breakdown

The KU Leuven Master of Mathematical Engineering is structured as a comprehensive 120 ECTS programme designed to be completed over two academic years. The curriculum balances compulsory foundations with flexible specialization, ensuring every graduate possesses both broad mathematical engineering competence and deep expertise in their chosen track.

The programme breaks down into five distinct components:

Each ECTS credit represents 25-30 hours of total work, including lectures, exercises, project work, and self-study. This means the full 120 ECTS programme demands approximately 3,000-3,600 hours of academic effort — a substantial commitment that reflects the programme’s rigour and the depth of mathematical competence graduates achieve.

Students can take up to 122 ECTS through additional courses via credit contract, providing extra flexibility for those who want to explore beyond the standard curriculum. The programme is available in both Dutch and English variants, which are currently considered equivalent. The university notes that most lectures are already delivered in English, and the programme is moving toward English-only lectures with Dutch support materials.

A key recommendation from the programme directors: take as many core courses as possible in the first year. This strategic front-loading of foundational material ensures you have the mathematical and computational tools needed for specialization courses and the master’s thesis in your second year.

Core Courses in KU Leuven Mathematical Engineering

The core education component (44-47 ECTS) builds the mathematical engineering foundations that all graduates share. Six courses are fully compulsory, totalling 27 ECTS, with an additional four-out-of-five selection that allows students to begin shaping their specialization from the outset.

Compulsory courses (27 ECTS):

• Optimization (6 ECTS) — Covers mathematical optimization theory and algorithms, forming a cornerstone skill applicable across all specialization tracks
• Nonlinear Systems (6 ECTS) — Addresses the behaviour, analysis, and control of nonlinear dynamical systems — essential for process control and simulation
• Scientific Software (5 ECTS) — Develops programming competence for scientific computation, with emphasis on software design practices relevant to engineering applications
• System Identification and Modeling (4 ECTS) — Teaches methods for constructing mathematical models from observed data, bridging theory and real-world systems
• Project Mathematical Engineering (3 ECTS) — A collaborative project integrating multiple course concepts into a practical engineering challenge
• Case Studies (3 ECTS) — Examines real-world applications of mathematical engineering, developing professional judgment and communication skills

Choose at least four from five (17-23 ECTS):

• Numerical Simulation of Differential Equations (6 ECTS) — Computational methods for solving ODEs and PDEs arising in engineering applications
• Advanced Process Control (6 ECTS) — Modern control strategies for complex industrial processes
• Data Mining and Neural Networks (4 ECTS) — Machine learning fundamentals including deep learning architectures
• Complex Analysis and Applications (4 ECTS) — Advanced complex analysis with engineering applications (note: may overlap with bachelor-level courses)
• Computer Algebra and Cryptography (3 ECTS) — Algebraic methods applied to modern cryptographic systems

The selective component allows students oriented toward data science to prioritize Data Mining and Neural Networks while skipping Complex Analysis, or process-control-focused students to emphasize Advanced Process Control. This flexibility within the core is a hallmark of KU Leuven’s approach to graduate engineering education.

Specialization Tracks: From AI to Cryptography

The four specialization tracks in KU Leuven’s Mathematical Engineering programme reflect the most in-demand areas where mathematical modelling intersects with technological innovation. Students must complete at least 18 ECTS in technical elective courses drawn from these tracks, though many choose to go well beyond this minimum.

1. Industrial Process Control builds on the core courses in system identification and nonlinear systems, extending into advanced control theory and its application to complex manufacturing and chemical processes. Graduates in this track are highly sought by the process industry, energy sector, and advanced manufacturing companies across Belgium and Europe.

2. Data Science and AI is perhaps the most rapidly growing track, reflecting the explosion of demand for professionals who can combine rigorous mathematical training with modern machine learning and artificial intelligence techniques. Building on Data Mining and Neural Networks, this track covers large-scale data analysis, graph-based ML methods, and advanced AI architectures. The 2024-2025 Capita Selecta course on “Large-scale Data Mining and ML on Graphs” exemplifies the cutting-edge topics available.

3. Scientific Computing and Simulation focuses on the numerical methods and computational techniques essential for engineering simulation. From finite element methods to high-performance computing, this track prepares students for careers in computational engineering, weather prediction, fluid dynamics simulation, and scientific software development.

4. Cryptography and Security leverages the programme’s strong algebraic and computational foundations to address one of the modern world’s most critical challenges: information security. Building on Computer Algebra and Cryptography, this track covers advanced cryptographic protocols, security analysis, and the mathematical foundations underlying secure communications.

Broadening elective courses extend beyond these four tracks to include Image Processing, additional Capita Selecta courses (which rotate annually), and individually proposed courses that typically support master’s thesis research. This structure allows ambitious students to develop genuine cross-disciplinary expertise — for example, combining Data Science and AI with Cryptography to work in security analytics.

Master’s Thesis Requirements and Process

The master’s thesis represents the capstone of KU Leuven’s Mathematical Engineering programme, accounting for 24 ECTS — equivalent to approximately 600-720 hours of research work. This substantial project demonstrates a student’s ability to independently apply mathematical engineering methods to a significant research or engineering problem.

Thesis topics become available each year in May, with a poster session showcasing ongoing thesis projects providing inspiration and insight into active research areas. Topics are supervised by faculty from both the Computer Science and Electrical Engineering (ESAT) departments, reflecting the programme’s interdisciplinary nature.

To begin the master’s thesis, students must have at most 72 ECTS remaining toward their diploma (including any bachelor and preparatory course requirements). In practice, this means having completed at least 48 ECTS, ensuring students have sufficient foundational knowledge to conduct meaningful research. The thesis is positioned in the second year (Phase 2) of the programme.

Academic integrity is strictly enforced. All thesis submissions undergo Turnitin plagiarism detection, and the programme notes that several students receive penalties every year. An online test on plagiarism awareness is required before beginning thesis work. The thesis coordinator, Prof. Giovanni Samaey, oversees the process and can advise on topic selection and research methodology.

Thesis topics typically align with one of the four specialization tracks but can also bridge multiple areas. Recent thesis projects have covered topics ranging from optimal control of autonomous vehicles and deep learning for medical image analysis to post-quantum cryptographic algorithms and numerical methods for multi-scale simulation. The quality of thesis supervision reflects KU Leuven’s position as a research-intensive university — students work alongside active researchers publishing in top-tier journals and conferences.

Admission Prerequisites and Remedial Courses

The KU Leuven Master of Mathematical Engineering assumes a strong foundation in several key areas. Understanding these prerequisites is essential for international applicants to plan their admission pathway effectively, especially if their undergraduate education differs from the Belgian engineering curriculum.
