Dr Lachlan H Yee BSc (Hons) Industrial Chemistry (UNSW), PhD Polymer Chemistry (UNSW) Dr Yee is a lecturer of chemistry in the School of Environment, Science and Engineering at Southern Cross University, Lismore, NSW, Australia. "The focus of my research is to develop environmentally benign and sustainable solutions to the challenges of pollution, biofouling and the need for active surfaces to combat exposure of materials to natural elements. This is achieved by using polymer chemistry in combination with naturally derived molecules to develop bioactive polymer surfaces that draw inspiration from nature (Biomimicry)." Examples of Dr Yee's research: • Living paints - Traditionally, toxic biocides were used to control marine biofouling. Alternatively, by combining bacteria capable of producing antifouling chemicals (e.g. anti-fungal) in a polymer to keeps them alive, it is possible to have a living antifouling system. • Biocatalytic coatings - Food surfaces and medical implants need to be bacteria free. Surfaces capable of delivering enzymes and signalling molecules use naturally occurring biochemicals to manipulate bacterial infection. These biochemicals can breakdown attachment glues or alternatively signal the bacteria to disperse from surfaces. • Hydrogel assisted bioremediation - Solutions required to stimulate natural organisms to break down harmful chemicals in soil can percolate too quickly through sandy or low holding soils. Polymer additives could slow the movement of a bioremediation solution through the soil thus increasing the effectiveness due to a longer contact time. Dr Yee is a chartered chemist and office bearer of the Royal Australian Chemical Institute, which is a valuable Australian resource for learning chemistry both in Australia and internationally.
