About

Dr Madoc Sheehan completed his PhD in chemical/environmental engineering (molecular dynamics and quantum mechanics modelling of solvent reactions) at UMIST in Manchester in 1999 before joining as a lecturer in the Chemical Engineering discipline at James Cook University in Townsville, Australia. He is currently a senior lecturer at James Cook University. Dr Sheehan has a diverse range of interdisciplinary research interests associated with process modelling, energy conservation, drying and de-watering. These include the development, validation and use of CFD, geometry and process systems models in the multi-scale modelling of particulate drying systems, particularly flighted rotary drying. Dr Sheehan has been modelling flighted rotary dryers for more than 20 years with direct experience in industries such as minerals processing (nickel and zinc), raw sugar milling and bagasse and macro algae drying. Dr Sheehan also researches bioreactor design, optimisation and life cycle analysis in bio-film microalgae and other applications. Dr Sheehan is a passionate teacher and has worked on the design and mapping of engineering curriculum in order to embed sustainability into undergraduate education. He has received National and Institutional teaching and learning awards for both his curriculum work as well as for innovations in his assessment and teaching practices.

Current and recent Research Funding to JCU is shown by funding source and project.

Queensland Department of Environment and Science - Advance Queensland Industry Research Fellowship

Identifying and eliminating future risk from regional Queensland wastewater treatment operations through biosolids technology innovation

Indicative Funding: $180,000 over 3 years, in partnership with the Townsville City Council ($182,976)
Summary: This fellowship will investigate emergent contaminant content in biosolids, technological solutions to mitigate its impact and how these new technologies can prevent future emergent contaminant related disasters. Six North Queensland city councils are investing in this research project to implement sustainable biosolids management technologies in wastewater plants to mitigate environmental pathogenesis and impact of new emergent pollutants in the region. This research project is aligned with two of the research priorities of JCU: Tropical Ecosystems and Environment and Industries, and Economies in the Tropics. This project will leverage new funding applications in the field of pollutants mitigation and agricultural industry.

Ecological Impact of Antibiotic Resistance Released from the Cleveland Bay Purification Plant using Marine Turtle Species

Indicative Funding: $260,139 over 3 years
Summary: Cleveland Bay is a grazing ground for turtle species. Cleveland Bay Purification plant (CBPP) treats waste that may contain a variety of antibiotics. This study aims to determine the prevalence and distribution patterns of antibiotic resistant genes in the CBPP effluent and in the immediate receiving environment. Marine turtles in Cleveland Bay will be used to determine the localized impacts of both antibiotics and antibiotic resistant genes as compared to resident turtles from a pristine environment. This study will provide valuable insight into the direct effect that antibiotics and ARG?s in WWTP effluent have on ecological health and ecological risk.

Townsville City Council - Contract Research

Assessment of the ecological risk of emerging contaminants released from the Cleveland Bay Purification Plant

Indicative Funding: $312,128 over 5 years
Summary: Discharge from the Cleveland Bay Purification plant (CBPP) is via ocean pipeline into Cleveland Bay and falls within the jurisdiction of the Qld State Marine Park Authority (QSMPA). A planned CBPP membrane upgrade has initiated a QSMPA operational permit, issued in December 2017., requiring Townsville city council to develop an Effluent Quality Assessment Program. The assessment program is to be developed under the guidance of a Special Technical Advisory Group (STAG) and should include effluent sampling of new and emerging contaminants, as identified in the Tropical water quality hub's NESP report (2015). This includes but is not limited to heavy metals, various organics (hydrocarbons, pharmaceuticals, poly-aromatics and personal care products) and micro-plastics. The assessment program's objective is to identify and prioritise emerging contaminants based on estimation of the current and longer-term ecological risk to the receiving environment.
Investigators: Madoc Sheehan and Brenda Govan in collaboration with Jochen Mueller, Anna Whelan, Ellen Ariel, Stephen Lewis, Edgar Salvador and Neil Mattocks (College of Science & Engineering, College of Public Health, Medical & Vet Sciences, The University of Queensland, Townsville City Council, TropWATER, Queensland Department of National Parks and Sport and Racing)
