Research Interests

  • Renewable energy conversion and storage
  • Device fabrication and efficiency characterization
  • Smart textiles

Dr Daoud graduated from the University of Technology Graz, Austria with a Dipl-Ing degree (BS and MS) in Chemical Engineering and received his PhD in bilayer photovoltaic cells from the University of Sheffield, UK. He then joined Possehl Besi Electronics Hong Kong in the semiconductor substrate industry as a process development engineer to establish a prototype reel-to-reel photoresist coating for high-precision plating. In 2002, he took up a postdoctoral position at the Hong Kong Polytechnic University (HKPU), where he played a substantial role in the establishment of a Nanotechnology Center in 2003 which earned him a research fellowship and lectureship at HKPU. In 2007, he moved to Monash University to take up a lecturer post and was promoted to senior lecturer in 2010. He joined City University of Hong Kong in the School of Energy and Environment in 2012.

Dr Daoud has been recognized for his work on the development and application of advanced materials. He has received international renown and several awards for his pioneering work on self-cleaning natural fibers using nanotechnology. This has been regarded as a breakthrough in the materials community and featured in Nature (2004) and Science (2008) and made headline news in major international media such as CNN, Discovery Channel, Reuters, MIT Technology Reviews, ABC, Daily Mirror, Telegraph, Sydney Morning Herald, Die Welt, and South China Morning Post.
