Biography:

Jack was raised in Auckland, New Zealand and studied a Bachelor's in Medicinal Chemistry at the University of Auckland. He obtained his PhD in 2010 under the supervision of Prof. Margaret Brimble FRS (University of Auckland). After postdoctoral studies with Prof. Varinder Aggarwal FRS (University of Bristol, 2011-2014) and Prof. Leonard Prins (Universita' degli Studi di Padova, 2014-2016), he commenced his independent career as a Lecturer in the School of Science at Auckland University of Technology (2016).

Current Research Projects:

Dynamic self-assembled systems responsive to external stimuli

Our group is interested in the way molecules self-organise into functional architectures. We are currently utilising self-assembly to construct dynamic structures that possess emergent properties. This is possible by utilising cooperative effects - where multiple functional groups work together to exhibit properties that are not observed in the original building blocks. Such dynamic systems allow the introduction of stimuli-responsive moieties that allow these systems to respond to chemical fuels, light and other external stimuli. Such responsive systems offer exciting possibilities for the development of smart materials and dynamic chemical systems with the potential to exhibit 'intelligent' and adaptive properties.

Featured Work

Reversible Formation of a Light-responsive Catalyst by Utilizing Intermolecular Cooperative Effects

Dynamic self-assembly allows the reversible formation of catalysts by exploiting intermolecular cooperative effects. This is achieved by incorporating photoresponsive units within amphiphilic pre-catalysts, which allows catalytic activity to be switched between the 'on' and 'off' states by irradiation with different wavelengths of light.

Substrate-Induced Self-Assembly of Cooperative Catalysts

A substrate is shown to induce the self-assembly of a cooperative catalyst, leading to its own destruction. Nature exploits the same strategy to obtain high-energy structures such as microtubules and to drive non-equilibrium phenomena.
