For the past 25 years, Leon Liebenberg has been engaged in engineering teaching, research, and community engagement. Leon is an associate teaching professor in the Department of Mechanical Science and Engineering at the UIUC. Before coming to the UIUC in 2017, he was a higher education consultant in Lausanne, Switzerland for three years. And prior to that he was a professor of mechanical engineering at the University of Pretoria and at the North-West University, South Africa.
Leon is passionate about multidisciplinary research, particularly in the fields of engineering education, energy engineering, and biomedical engineering. His university research has focused on development of industrial energy-efficient technologies and cancer therapies using energy restriction methods, as well as developing novel pedagogies of engagement.
His first love is however for teaching. At the UIUC he founded the strategic instructional innovations program called ENGINE (ENgaGement In eNgineering Education); he collaborates with 15 faculty from various disciplines where they explore the relationship between pedagogies of engagement and cognition and emotion, to better understand how we may engage students more fully in their learning, reflection, and testing of ideas.
In 1997, Leon co-founded the TechnoLab technology awareness facility for junior engineering students and for school children, where learners work in small teams to solve problems using Lego Dacta and employing roleplay. The TechnoLab model has been adopted by several South African schools since its inception. Leon also founded the Space and Aviation Challenge for school learners in South Africa, which aimed at demystifying the aeronautical engineering profession by employing several simulation-based activities. The Challenge was annually presented for several years in collaboration with Nasa (Houston) who offered the first prize for a learner to attend Space Camp USA.
Leon teaches a variety of subjects, including: Innovation; Statics; Dynamics; Thermodynamics; Fluid Dynamics; Automatic Control Systems; Design for Manufacturability; Mechanical Design; Energy Conversion Systems, Heat Transfer; Aerodynamics; Aeronautics; and Advanced Heat and Mass Transfer.
Leon holds a diploma in advanced mechanical engineering from the University of London, a masters degree in mechanical engineering from Imperial College London, and bachelor's, master's, and doctoral degrees in mechanical engineering from the University of Johannesburg.

Other Professional Activities
- Inaugural Fellow of the Center for Innovation in Teaching and Learning (CITL); Co-Chair of CITL Faculty Fellows program, 2019-2020, and 2020-2021
- In 2016 I was a Top 30 Finalist (out of 2300 entries) for the 2016 Rolex Awards for Enterprise for development of a social network game (with real-world problem-solving component) addressing sustainable development, cultural values, and lifestyle effects. The same gamification techniques and game mechanics can be used to drive student or customer engagement and change behaviour, attitudes and beliefs. I am currently investigating the incorporation of several gamification techniques to help enhance emotional learning in the mechanical engineering curriculum at UIUC.
- At the North-West University, I Increased the number of research outputs emanating from the Centre for Research and Continued Engineering Development (CRCED-Pretoria) by 450% through intensive mentoring of postgraduate students, by recruiting new (part-time) students from various organizations, and by co-authoring research publications.
- At the University of Pretoria, I co-developed and taught a unique first-year course in “Innovation”, lectured every year to 800 freshmen engineers. The 10-month course helped students discover the power of wholebrain thinking in problem-solving, as well as the usefulness of roleplaying certain metaphorical mind-sets (personas) when tackling a challenge in teams.
- At the University of Pretoria, I founded the research publication, “Innovate”, the “Space and Aviation Photographic Competition” for school students (with Kodak SA), and the annual national “Space and Aviation Challenge” for school students (in collaboration with NASA’s International Space School, Houston), initiatives all credited with attracting top performing students to the university and increasing collaboration between different departments within the university.
- I founded and led the University of Johannesburg’s TechnoLab facility, an innovative way to bring technology awareness to school students and teachers. The program has reached in excess of 60,000 students and teachers since its inception in 1997, using a unique team-based approach to solve technological problems using mainly Lego Dacta as a didactic medium.
- During compulsory national military service in the South African Navy (1980 - 1982), I was Executive Officer of a naval support vessel, SAS Fleur, with a complement of 30 sailors and five officers.
- Non-toxic modification of the human energy metabolism to help control prolific disorders, with emphasis on glucose-hemodiafiltration
- Cross-disciplinary research activities focusing on energy system optimization and heat transfer enhancement
- Collaborative intelligence techniques in engineering teaching and learning, with a focus on "self-directed learning", "pedagogies of engagement", "learning through play", "design-thinking", and stimulation of "emotional learning"
