Research Interests

My research cluster(s):

Using synthetic methodology we aim to design and construct molecules capable of sequestration and removal of both cationic and anionic components in dual phase systems. We are working in conjunction with collaborators from Los Alamos National Laboratory and The University of Edinburgh and using techniques such as computational chemistry methods (structural prediction), X-ray crystallography, ESI-MS, electrochemistry and various spectroscopic techniques.


Anion binding using supramolecular chemistry

Anion recognition and encapsulation is fast becoming a new frontier in supramolecular chemistry. Current worldwide research directions are focussed on passive anion recognition through rigid preassembled anion binding sites. This project involves the design of dynamic anion binding receptors that switch between differing geometric types and charges of anions with the application of a driving force (e.g. an applied electrical potential). A combined experimental and computational approach will be used which initially will involve the design, construction, and testing of various systems for their ability to bind suitable anions.


Beryllium binders

Beryllium is a unique and valuable metal that is a component of materials indispensable in today's aerospace and electronics industries. However due to the toxicity of beryllium, little attention has been spent on the exploration of the co-ordination chemistry of this metal. With the introduction of beryllium into consumer products, there is some concern for the spreading of beryllium containing substances into the environment. In order to safely protect the environment from beryllium contamination, whether from manufacturing waste streams or discarded consumer products, suitable clean up and detection methods must first be established. A typical procedure for the removal of metal hazardous metals in waste streams is to use an organic molecule which selectively binds and complexes the metal. This project will design such systems.

In addition to the above core projects, smaller projects are available which will focus on the improvement in accuracy of various computational methods in predicting properties of molecules.
