Research Summary

Lachlan Yee

Dr Yee has made significant contributions to the interdisciplinary field of polymer science and bacteria in environmental arenas. In the area of polymer science, he has a thorough grounding in the manipulation and measurement of rate kinetics for free radical polymerisation reactions. This was then applied to the kinetics of photochromic dyes in polymer matrices.

His recent research emphasises the utility of polymer science as a powerful platform to overcome a number of environmental challenges such as marine biofouling where he published the first ever report of a living polymer immobilised bacterial biofilm that produced antifouling compounds to effect a significant reduction in algal and larval settlement in the field.

Dr Yee has also reported on the biodegradation of polyhydroxybutyrate, polyhydroxybutyrate-co-valerate and polyhydroxyoctanoate in soil via biofilm bacteria where the first ever reports of the importance of bacterial adhesion modes contributes to the rates of biodegradation of the polymers.

Significantly, he has also published on the topical environmental issue of polychlorinated organic pollutants in soil and how the dechlorination of hexachlorobutadiene in soil can be facilitated by the novel combination of alginate polymers and a nutrient solution including electron shuttles to biostimulate dehalogenating biofilm bacteria.

Recently, Dr Yee has been appointed the Chemistry lecturer at the Southern Cross University (2010) where he continues to research the nitric oxide communication chemistry of bacteria within a biofilm and how can polymers be harnessed to deploy such communication signals as well as marine ecologically relevant compounds for the settlement and metamorphosis of coral and urchins respectively.
