Thomas Nann joined the Ian Wark Research Institute in June 2010. Previously he held the Chair in Nanosciences at the University of East Anglia (UEA), UK for almost 4 years. His work at UEA was focussed on the synthesis of novel nanomaterials and their application in bioanalysis and energy harvesting. Prior to this, he held the position of Senior Lecturer (German: Privatdozent) at the Freiburg Materials Research Centre at the University of Freiburg, Germany, where he led a research group of approximately 10 PhD-students and Post-doctoral research assistants.
Thomas was awarded with his Habilitation (including venia legendi) in
2004 for his research in the field of nanosciences. Later in 2004, he spent
a scientific sojourn at the laboratory of Paul Mulvaney in Melbourne,
Australia. Thomas received his PhD in 1997 from the University of Freiburg
and his PhD supervisor was Jugen Heinze. During his PhD studies, he performed
research into electrochemical processes at heterogeneous phase boundaries
(electrodes). Thomas also studied chemistry at the Universities of Stuttgart
and Freiburg (Germany) between 1989 and 1994.
Thomas acts as PhD supervisor for students who undertake PhD and Masters projects in the well-equipped nanoscience laboratories at The Wark. These PhD projects provide fundamental knowledge on nanochemistry, surface and colloidal chemistry, photoelectrochemistry and various analytical techniques, including spectroscopy, electrochemistry, electron-microscopy and bioanalytical methods.
Thomas' mother tongue is German. He speaks English and some French.
Thomas' current research interests comprise synthesis, characterisation and application of nanomaterials. More specifically, he is interested in the following materials and methods:
- Semiconducting nanocrystals (Quantum Dots)
- Metallic nanoparticles
- Magnetic nanoparticles
- Various types of heterogeneous and doped nanoparticles. Examples include heterogeneous core/shell, silica particles and up-converting (rare-earth doped) particles.
- Wet-chemical synthesis and modification (functionalisation) of nanomaterials
- Chemical synthesis of functional ligands and reactants
- UV/vis, photoluminescence and other spectroscopies
- Electrochemical methods (including photoelectrochemistry and cyclic voltammetry)
- Electron microscopy (especially transmission electron microscopy)
- Standard chemical and bioanalytical characterisation methods
- Energy conversion; especially solar energy conversion
- Bioanalytical techniques
- Medical diagnostics and drug delivery
Much of Thomas' research is interdisciplinary and performed in close collaboration with chemists, physicists, biologists and clinicians at other institutions and companies.
