Sudesh L Wijesinghe (Dr)
Scientist III
Surface Technology

Sudesh is a scientist, specialising in the areas of corrosion and electrochemistry. He received his PhD from the Department of Materials Science and Engineering, National University of Singapore (NUS) in 2005 and went on to work in the department as a Research Fellow until 2008. Following this, he joined SIMTech with an interest in developing capabilities in corrosion testing and research. Sudesh is the Team Leader of Corrosion Characterisation and Protection Team, Surface Technology Group of SIMTech. He is also an Adjunct Assistant Professor at NUS. Sudesh has more than 40 journal and conference publications.

Research Interest:
  • Corrosion mechanisms and concepts for different corrosion problems

  • Methodologies for corrosion investigation

  • Corrosion protection strategies (materials and design selection, advanced coatings etc)
