Research

There is a wide variety of leading research being done in this department. This includes work on novel drugs, environmental analysis, supramolecular chemistry, optoelectronics, spectroscopy and sensors.

Research themes in the department include:

 


Organic Synthesis and Biological Chemistry

Organic synthesis is used in the construction of biological molecules and drugs, and this department has excellent research links with other departments such as biochemistry, physiology and pharmacy. New methodology is also being developed for the enantioselective synthesis of chiral compounds.

Environmental Chemistry and Geochemistry

This is the leading Environmental Chemistry tertiary research group in New Zealand. Specific areas of interest include: marine and freshwater chemistry, biogeochemistry, paleo-climatology, paleo-oceanography, cosmochemistry, isotope geochemistry, and the the fate of organic contaminants. Specialist units that support these research activities include: Isotrace, the Centre for Trace Element AnalysisNIWA/University of Otago Research Centre for Oceanography, and the Centre for Organic Geochemistry and Paleoclimate Studies.

Prof. Keith Hunter:

Theory and Modelling

Modelling is important to fully understand and predict the chemistry and reactivity of molecules, and to help assign spectral features for analysis. While many researchers here use computational models occasionally, the groups of Garden and Gordon employ a full raft of high level techniques as a large part of their work.

Theoretical modelling of heterogeneous catalysis and nanoparticle structure

Physical Chemistry and Spectroscopy

Spectroscopy is used to study and help model a wide variety of areas, including atmospheric interactions, bio-adsorption and solar cells. Spectroscopic methods are also used, with chemometrics, for composition analysis in pharmaceuticals, foods and fossils.
