Courses Taught

The core of his teaching philosophy lies in connecting theory to real-world issues through relevant, real-life applications and active student engagement. His primary goal is to transform passive learning, moving students beyond simple memorization toward true cognitive agility. He achieves this by integrating live demonstrations and utilizing physical specimens to ground complex chemistry in the physical world. He employs in-class activities and group-based tutorials to foster peer-to-peer teaching, which reduces student stress and builds confidence in solving complex problems from multiple angles. By designing interdisciplinary assignments with intentionally missing data, he places students in an investigative mode, requiring them to navigate real scientific datasets to find valid solutions.

He has also contributed to lifelong learning and professional knowledge exchange. For example, he was a lead organizer and lecturer of Sustainable Waste Management and Smart Urbanisation, Center of Professional and Continuous Education (PACE), NTU for Ministry of Foreign Affairs (Singapore Cooperation Programme).

Supervision of PhD Students

He is spervising 11 PhD students as main supervisor, 2 PhD students as co-supervisor and 5 Master students as main supervisor. He have graduated 10 PhD students as main supervisor, 1 PhD student as co-supervisor and 4 Master students as main supervisor. He successfully mentored 58.5 FYP and 14 URECA students. He is currently supervising 10 FYP and 1 URECA students. He served as examiner of Qualification and PhD exams: 40 times (total) with 25 times (since promotion to Assoc. Prof.). His students were recognized by receiving a number of awards: 10 (total) and 7 (since promotion to Assoc. Prof.), including my PhD student, Jiahui Bu, 2026 winner of the “Best Posters” award at the CEE PhD student competition, and URECA student Xan Ng Junn Han, 2024 runner up prize for the best URECA poster in the category of Civil and Environmental Engineering.

Dr. Lisak research is focused on applying advanced thermochemical waste conversion techniques to transform residues, historically viewed as environmental liabilities, into valuable resources. His vision is to fundamentally redefine the waste management landscape, shifting the focus from simple volume reduction to a Circular Waste-to-Resource model that aligns with national and global sustainability targets. His work integrates three critical pillars:

  1. Advancing Waste-to-Energy (WtE): Moving beyond energy recovery to secondary resource reclamation and CO₂ capture.
  2. Thermochemical Resource Recovery: Developing pathways for municipal solid waste (MSW), plastics, biomass, and sewage sludge.
  3. Real-time Assessment Platforms: Engineering sensing technologies to validate the safety of waste and waste-derived products.

This multi-disciplinary approach links fundamental environmental engineering and large-scale industrial infrastructure, with “waste” being the primary feedstock for a low-carbon economy.
