The Value Of a One Health Approach For Mitigating Infectious Disease Outbreaks
Dr. Maurizio Labbate, University of Technology Sydney (UTS)

The Value Of a One Health Approach For Mitigating Infectious Disease Outbreaks

Event date: 13 November 2018 - 12:00pm to 1:00pm
Event type: Seminar
Venue: ASE 3-D Visualization Lab (N2-B1c-16c)
Speaker: Dr. Maurizio Labbate, University of Technology Sydney (UTS)
About the speaker:

Maurizio holds a Bsc (Hons) and PhD in Microbiology and has published approximately 50 documents including journal publications, book chapters, books and policy-related papers. He has attracted over AU$3 million dollars in external funding and leads a research group with core expertise in bacterial evolution with a strong focus on lateral gene transfer, the mechanism by which bacteria share genetic information. His research groups’ broad goal is to apply their core expertise in bacterial evolution to address One Health problems that straddle environmental, medical (e.g. antimicrobial resistance) and agricultural sciences (e.g. diseases affecting aquaculture).

Over the last 5 years, Maurizio has expanded his research activity to include One Health principles – a concept that recognises the links between human, animal and environmental systems in infectious disease and therefore, requires approaches to be multidisciplinary. As a result, he has led or participated in highly collaborative research that integrates expertise across multiple disciplines including microbiology (medical and environmental), eco-toxicology, microbial ecology, aquaculture, veterinary science, social sciences (including human geography) and decision-making, policy development and One Health governance. He has engaged with the Australian Federal Government unit responsible for Antimicrobial Resistance policy making in order to address explicit knowledge gaps they identified. In addition, he has engaged with the NSW Department of Primary Industries and associated oyster farmers to address infectious diseases affecting the industry. His capacity to work across the field of bacterial evolution and applied human/policy sciences provides him with a unique capacity to draw links between human behaviour and infectious disease problems and subsequently to generate effective policy responses, ensuring his research engages with end-users and has an impact.

Maurizio’s research in antimicrobial resistance is recognised nationally and internationally. He is an advisor on the board for Global Alliance for Infections in Surgery and was Rapporteur at the 2016 Australian Academy of Sciences Theo Murphy High Flyers Think Tank. He contributed a commentary to the AMR Control 2017 book alongside contributors such as the World Bank Group and The Federal Republic of German Ministry and engaged in public outreach including the publication of two articles in The Conversation on antibiotic resistance. He has been invited to be on the Scientific Advisory Committee and Local Organising Committee for Global Health Security 2019 in Sydney.


The One Health concept recognises that the health of humans is closely linked to the health of animals (wild and food-producing) and the wider environment (urban and natural). It a concept that aids in the understanding of how disease-causing microorganisms (pathogens) emerge and spread resulting in infectious outbreaks in not only humans but also animals and plants. The emergence of pathogens is complex and is often preceded by the convergence of numerous factors entitled the “perfect microbial storm” – these factors sit within or across one or more of the human, animal and environment domains. Due to the complexity of pathogen emergence, interventions require stakeholders across disciplines and sectors to work together in a multidisciplinary approach or a One Health approach. This teaching seminar will expose students to the concept of One Health and a One Health approach and will help them understand the complexity of infectious disease using three examples. It will prime students to look at infectious diseases through a One Health lens and help them develop skills in generating interventions that can be implemented not only after but prior to an infectious outbreak thus reducing the risk of them occurring in the first place.

Glacial isostatic adjustment-based refinements of deglaciation history: the case of Heinrich event 1 and the “Mystery Interval”

Glacial isostatic adjustment-based refinements of deglaciation history: the case of Heinrich event 1 and the “Mystery Interval”

Event date: 13 November 2018 - 4:00pm to 5:00pm
Event type: Seminar
Venue: ASE 3D Viz Laboratory Room (N2-B1c-16c)
Speaker: Richard Peltier
About the speaker:

Richard Peltier is currently University Professor and Professor of Physics at the University of Toronto from which he received his doctoral degree in the same subject. He also holds an honorary doctoral degree from the University of Waterloo. Wikepedia lists all of his distinctions.  In 2004 he shared, with Nick Shackleton, the Vetlesen Prize in Earth Science from the Vetlesen Foundation of New York and in 2010 was the recipient of the Bower Award and Prize of the Franklin Institute of Philadelphia for his research on “Earth Systems”. In 2012, he won the Gerhard Hertzberg Canada Gold Medal in Science and Engineering, Canada’s highest scientific award, and in the following year the Killam Prize in Natural Science of the Canada Council for the Arts. He is the Director of the Centre for Global Change Science at the university of Toronto and Scientific Director of the SciNet high performance computing facility, the leading facility of this kind in Canada.


Important contributions have been made to the understanding of Quaternary climate variability thro ugh application of the formalism that has been developed to understand the glacial isostatic adjustment process. Nevertheless there remain significant issues concerning the nature of ice-earth-ocean interactions in regions in which ice on the periphery of continental ice sheets is initially grounded below sea level. One such region that has been the focus of recent research consists of the Ross Sea and Weddell Sea embayments of Antarctica. More important, but much less well understood, are issues surrounding the ice streams through which the Laurentide ice sheet of North America interacted with the oceans during the glaciation-deglaciation process. An especially important example of this interaction is that which involved the Hudson Strait ice stream which, during both Marine Isotope Stage 3 (MIS3) and during the deglaciation process, became intensely unstable. Such instabilities were responsible for the so-called Heinrich Events, which were themselves the cause of the millennium timescale Dansgaard-Oeschger oscillations which dominated climate variability during MIS3 but also during deglaciation. The most recent Heinrich event, referred to as H1 and which began approximately 16,800 years ago, was ultimately responsible for the Bolling-Allerod warming event and meltwater pulse 1A in the Barbados record of deglacial sea level history. I will discuss ongoing work directed towards the development of a rigorous theory of Heinrich events. This begins with the demonstration that radiocarbon dated relative sea level histories can be employed to unambiguously demonstrate that Heinrich events do involve instability of the Hudson Strait ice stream. I will then discuss the physical mechanisms that control the approximately 7000 year repeat time between successive such events in MIS3 as well as the forcing by the M2 tide which appears to be responsible for the initiation of instability.
