Career overview

Dr Puddu graduated in Chemistry from the University of Cagliari in 2004 and achieved her PhD in Chemical Engineering from the University of Nottingham in 2008. She joined NTU in 2009 as a post-doctoral Research Associate in the Biomolecular Materials Interface Research Group. She was appointed Lecturer at NTU in 2013.

Research areas

Dr Puddu has carried out research on the following areas:

  • Photocatalysis: synthesis TiO2 based photocatalysts and evaluation of their photocatalytic activity for indoor air and water remediation.
  • Interfacial studies: study of the interactions at the bio-inorganic interface, in particular binding properties of short peptides on silica substrates; and biomineralisation of TiO2.

Dr Puddu's current research interest is focussing on the development of inorganic nanomaterials for solar applications, eg. solar photocatalysis, solar cells, water splitting etc. Of particular interest is the design and development of efficient visible and near-IR light harvesters, in the form of inorganic nanocomposites or obtained by TiO2 surface functionalization.
Another area of research is exploring the potential applications of these materials as photoresponsive cancer treatment and drug delivery systems.

Opportunities to carry out postgraduate research towards an MPhil/PhD exist in the School of Science and Technology and further information may be obtained from the NTU Graduate School.
