- Planned and executed restoration in threatened and protected ecological communities including coastal wetlands, lowland rainforest on floodplain, saltmarsh, coastal heath, and over a dozen other ecological communities unique to SE QLD/N NSW. - Restoration work included threatened flora translocation/propagation, fauna trapping/ surveys, mass restoration planting, and assisted regeneration. -Planning restoration work involved ecological site assessments, ecosystem mapping, and state/council approvals. - Planned and managed environmental impact of construction projects inducing highway upgrades, airport infrastructure upgrades, and residential subdivisions. -Planning included groundwater and soil investigations for groundwater/contaminated land/acid sulfate soil assessment and de-watering modelling. -Planning included pre-clearing walk throughs and spotter-catcher work. -Management included erosion and sediment control design and modelling. -Relocated terrestrial and aquatic fauna as part of de-watering and clearing works.

Environmental, Health and Safety Compliance Coordinator
-
Sep 2014 - Apr 2015
• Sampled and analyzed influent and effluent wastewater streams on a daily basis, screened for organic contaminants and metals using gas chromatography and atomic absorption spectroscopy. • Sampled and analyzed petroleum products for specific gravity and flash point. • Managed the laboratory by maintaining current chemical records and inventory, calibrating and creating standards for pH meters, gas chromatographers, and the atomic absorption spectrometer. • Maintained health and safety standards by coordinating with county health and safety inspectors and coordinating the appropriate trainings and retrofits. • Operated the refinery and wastewater treatment plant: adjusted the distillation unit, ran the wastewater treatment plant.

Aug 2009 - Jul 2011
• Synthesised PMMA cylinders doped with nanodots. • Measured redshift of Pb/Se nanodots in PMMA cylinders to understand the efficiency of nanodot luminescent solar concentrators. Designed, set up, and executed the redshift experiments. • Analyzed redshift experiment data using Origin. • Collaborated on research and development by presenting, interpreting, and discussing results with an interdisciplinary team of scientists, engineers, shareholders, and supervisors in weekly meetings. • Coauthored article “Cylindrical Luminescent Solar Concentrators With Near-Infrared Quantum Dots,” Optics Express Journal, V. 19, I. 24.
