We offer a structured Master’s programme in Chemical Engineering, with a focus on Data Analytics. This postgraduate degree will equip engineers with the fundamentals of data science — specifically machine learning — and enable them to apply newly developed methods in the context of large, integrated industrial processes. The course is specific to the process industry, considering topics such as plantwide dynamics and advanced process monitoring and control. Focussing on the fundamentals of machine learning, we encourage engineers to understand the methods they employ rather than implementing black-box solutions.

Who is the programme for?
The structured Master’s programme will equip engineers with the fundamentals of data science — specifically machine learning — and enable them to apply newly developed methods in the context of large, integrated industrial processes. The course is specific to the process industry, considering topics such as plantwide dynamics and advanced process monitoring and control. Focussing on the fundamentals of machine learning, we encourage engineers to understand the methods they employ rather than implementing black-box solutions.
How is the programme structured?
Students register for 180 credits over the duration of the programme, including eight taught modules and one research project module. Each taught module is 15 credits, amounting to 150 notional hours of work. A typical module consists of two weeks of pre-reading, followed by a block week which may be attended online or on campus. The final part of each module is a six-week post-block period where students will work on assignments (collaboratively and individually). Most assessments take the form of an assignment and do not require students to be on campus.
The block week provides an opportunity for students to critically engage with their lecturers and peers on fundamental concepts as well as applied problems. Students are not required to attend the block week in person on Stellenbosch campus: it is offered in a hybrid mode, serving students attending in person or remotely. However, the block week is a synchronous session. Students are thus required to actively participate in real-time, whether on campus or online. As such, students will be required to attend the full block week during normal working hours; part-time students will likely have to apply for study leave to do so. This is opposed to the pre-reading and post-block sessions, which are asynchronous: students engage with the content and work on assignments in their own time.
Lastly, students undertake a 60-credit research project (i.e., 600 notional hours of work) as the final step towards earning their degree. During this time, students will work on a complex, relevant problem in the field of process data analytics. They are supported in their research through individualised supervision from experts in the field.
An outline of the programme and individual modules are provided below.
What are the admission requirements?
All applicants must meet the minimum admission requirements as detailed in section 3.6 in the Engineering Calendar, Part II. The minimum selection criteria for the Data Analytics focus area is a BEng or BSc (Eng) degree in a discipline that has provided previous exposure to control systems (typically chemical, mechanical or electronic engineering). All applicants who meet the criteria undergo a selection process and are approved by a departmental committee that considers applicants’ academic record as well as relevant industry experience.
What does the application process involve?
Candidates are required to complete and complete and submit an institutional application. Compulsory documents include your academic record(s) and degree certificate(s), a comprehensive curriculum vitae, and a cover letter.
Under Evidence of Written Academic Work applicants are required to upload a cover letter (limited to one page only, please) detailing all prior learning and/or industrial experience as it relates to the programme’s minimum admission requirements, specifically exposure to control systems. Appropriate prior learning may include relevant undergraduate training, e.g. Chemical/Mechanical/Electrical Engineering degrees or short courses. In the absence of relevant prior learning, industrial exposure must be thoroughly described.
The application process towards registration is as follows:
- Application: Candidate applies for the programme via SUNStudent: https://student.sun.ac.za/signup/. Once the application is submitted, the Central Admissions Office reviews the application.
- Selection: After the programme’s application deadline, we’ll draw all reviewed applications from the system and the programme coordinators will review the applications according to the programme’s selection criteria. The list of candidates who meet the selection criteria will serve for approval at a departmental management meeting. All applicants will be informed of the outcome of their application.
- Admission: Successful candidates will receive conditional offers via the application portal, which they must accept, and thereafter another final offer will be issued that candidates must also accept.
- Registration: This will take place at the start of the new academic year towards the end of January when registration opens. Admitted candidates will receive communication in this regard.
The programme overview for both full-time and part-time registering students are given below. Due to pre-requisite requirements, the module structure is fixed, and students will be required to enrol for the specific modules per academic year as indicated below.
The scheduling of the modules for the following academic year are subject to change (as decided by the host department) and communicated to students well in advance, allowing sufficient time to plan and manage schedules.
When do classes take place?
For students registering for the first-year of the programme in 2024, the modules’ block weeks are given below.
Students must plan to set aside approx. 10 – 15 hours per week during the pre-reading and post-block weeks.
During the block week, candidates must be available full day to attend lectures online or in person.

Integrated Process Data Analysis
Data science is the application of computational, statistical, and machine-learning techniques to gain insight into real-world problems. The focus of this module is on the data science project life cycle, specifically to gain a clear understanding of the five steps in the data science process, namely obtain, scrub/wrangling, explore, model, and interpret.
Pre-requisites: Knowledge of an appropriate coding language (e.g. Python).
Understanding the theoretical underpinnings of several machine learning techniques is essential for data analysis. This module emphasises an understanding of the requirements, inductive bias, advantages and disadvantages of these techniques to real-world problems, and this provides exposure to the various machine-learning methods.
Pre-requisites: Data Science (Eng) 874
Different classes of optimisation problems occur in the engineering domain, each characterised by various complexities. A wide range of advanced meta-heuristics and hyper-heuristics can be used to solve these different classes of optimisation problems. Students will gain experience in implementing advanced optimisation algorithms to solve real-world engineering problems.
Pre-requisites: Applied Machine Learning 874
Matrix computations are required for almost all machine learning techniques. This module investigates the effective solution of linear systems involving both square and rectangular matrices. Direct as well as iterative methods are considered, with an emphasis on sparse matrices and matrices with structure. Numerical methods for the eigenvalue problem are also considered.
The purpose of the module is to present principles of general management within the context of technical disciplines. The course themes include the business environment and strategic management on a firm level, touching on the role of innovation and technology for competitiveness on a systems level from international and national perspectives.
The analysis of dynamic time-series data presents a variety of challenges but is well supported by classical control theory as well as new developments in machine learning. This module will require students to develop a practical understanding of traditional approaches to analyse and leverage data produced by measurements of dynamic processes specific to the chemical and minerals processing industries, including systems identification, data reconciliation, and state estimation. Students will also be required to use contemporary statistical and machine learning tools for time series analysis.
