Research

The questions I work on, and the projects where I work on them.

Interests

  • Sensors and sensing materials

    Metal-oxide and polymer sensing films for pH and electrochemical sensors, including extended-gate field-effect transistors (EGFET) on flexible substrates. Recent work covers sol–gel and electrospray-deposited TiO2 electrodes and soil electrochemical sensing.

  • Memristors and memristive devices

    How memristive metal oxides such as titania respond to their environment, and how that behaviour can be used for sensing. This work was funded by national Niche Research and Exploratory Research grants.

  • Semiconductor materials fabrication and characterisation

    Thin-film growth by sputtering, e-beam and thermal evaporation and spin coating, characterised by SEM, FESEM, XPS, Raman, AFM and electrical analysis. Projects include ZnO thin films and nanorods on flexible substrates and low-temperature poly-Si on glass.

  • Nanotechnology

    Nanostructured materials, from ZnO nanorods to carbon nanostructure hybrid films and superhydrophobic nanostructured electrodes, used to make sensors more sensitive.

  • STEM education

    Programmes that bring robotics, electronics, computational thinking and AI to school students and young innovators, with over RM 900,000 in sponsorship since 2015. I am an IEEE STEM Champion and have led programmes with MDEC, CelcomDigi, Maxis and BRIDA NTB in Indonesia.
