I completed my Bachelors of Science with honours at the University of Queensland. My honours which I undertook in the Coral Reef Ecosystems lab focused on coral physiology and climate change with field and tank based experiments on Acropora corals at the Heron Island Research Station. I am now completing my PhD investigating coral growth dynamics and small scale population genetics. My research aims to investigate how corals in locations with stark environmental contrasts show differing growth strategies on a species level, and whether there is evidence for this having a genetic basis.
I have studied coral reefs from molecular to community levels. My general interests are in understanding the mechanisms by which marine organisms respond to environmental forcing in their ecological context, to improve predictions of ecosystem responses to multiple stressors such as climate change, habitat degradation and fishing.
I completed my bachelor and master degree studies in Colombia while exploring Caribbean reefs. During my masters’ degree, I investigated the genetic diversity and dispersal of Symbiodinium spp. by the stoplight parrotfish Sparisomaviride (Castro-Sanguino & Sanchez 2012).
In 2012 I moved to Australia to pursue my PhD at the University of Queensland. My PhD research focus on the ecological drivers of the marine calcareous algae Halimeda, one of the greatest contributors to reef carbonate sediments. Here, I combined long-term field-based experiments (Castro-Sanguino et al 2016) and laboratory experiments (Castro-Sanguino et al 2017) to quantify the interactive effects of temperature, light, nutrients, and herbivory on Halimeda growth dynamics. Based on these results I developed a mechanistic, individual-based model of Halimeda population demographics to estimate Halimeda’s contribution to reef carbonate sediment production (Castro-Sanguino et al 2020).
My postdoctoral experience has involved meta-data analyses to investigate the effect of fishing on reef fish and benthic communities of the northern Great Barrier Reef (GBR) (Castro-Sanguino et al 2017). My work at the Global Change Institute (in 2018) and at the Australian Institute of marine Science-AIMS (in 2019) focused on assessing impacts of multiple stressors (e.g. water quality, cyclones, bleaching, crown-of-thorns starfish, CoTS), on coral population dynamics along the GBR. Currently, my work at MSEL aims to help developing a decision-support system for controlling CoTS, one of the greatest threats on the GBR.
John Tanzer originally trained in the disciplines of geography and economics, completing an honours degree at James Cook University in 1980. Since that time he has worked in a number of areas of natural resource management and policy particularly in the marine and coastal realms. He holds a master’s degree in environmental law from the Australian National University.
Mr Tanzer was appointed as the inaugural Chair and Chief Executive of Queensland’s Fisheries Management Authority (QFMA) when it was first established in 1994. In 1998 he was appointed as Executive Director of the Great Barrier Reef Marine Park Authority (GBRMPA) the Federal Government agency responsible for the management of the Great Barrier Reef. He served in this position and as Acting Chairman for 10 years. During his service in this position and also as the Acting Chairman, he led the Commonwealth’s negotiations to develop the East Coast Trawl Plan and the Reef Line Fishery Plan. Most notably from 2001 onwards he was the Executive Director responsible for the oversight of the spatial rezoning of the Great Barrier Reef Marine Park based on the Representative Areas Program (RAP) which resulted in highly protected area increased from around 5% to over 33% of the 350,000sq kilometre park.
Mr Tanzer represented the Australian government at the first Coral Triangle Summit in Bali in December 2007. Between July 2008 and December 2012 he worked with the international NGOs –WWF and The Nature Conservancy to assist with the development of the Coral Triangle Initiative. In this role he worked extensively throughout the region. He also worked as an advisor to an alliance of Australian universities to provide capacity development to the countries and institutions of the Coral Triangle.
In February 2012 he joined WWF International as the Director, Global Marine Program. John was then appointed as the Leader of the WWF Oceans Practice in late 2016. His responsibilities include development and implementation of a new global oceans strategy. The focus of his work is to support the effective implementation of the Sustainable Development Goals especially SDG14.
Amatzia is a visiting professor from Eilat, Israel, on 2 years of Sabbatical leave at CRE (November 2018 – September 2020)
I am a marine ecologist and biological oceanographer. My major interest is in the coupling between physical and biological processes in the marine environment, focusing on the effects of water motion on fundamental ecological processes, including predator-prey relationships, competition, symbiosis, mass transfer, and behavior. Research at my lab is process-oriented and inter-disciplinary, addressing mechanisms that operate at levels ranging from the individual to the ecosystem. Most of my studies are based on field experiments involving advanced technologies and novel approaches.
I completed my BSc (1977) and MSc (1981) at the Hebrew University of Jerusalem, Israel and PhD (1987) at Scripps Institute of Oceanography, UC San Diego, USA. I have been a faculty at the Hebrew University of Jerusalem and a resident researcher at the InterUniversity Institute for Marine Sciences of Eilat (IUI) since 1987. In the past 6 years (2012-2018) I was the scientific director of the IUI.
David Obura is a Founding Director of, and works at CORDIOEast Africa, in Mombasa, Kenya – www.cordioea.net
CORDIO is a knowledge organization supporting sustainability of coral reef and marine systems in the Western Indian Ocean. CORDIO takes research to management and policy, builds capacity, and works with stakeholders, managers and policy makers.
David’s primary research is on coral reef resilience, in particular to climate change, and the biogeography of the Indian Ocean. At the boundary between science and action, David works to integrate conservation and development through inclusive blue economy principles and links provided by global sustainability goals and targets.
He works from the local scale, through fostering innovative action to promote sustainability, through regional scale alignment and integration such as in the Northern Mozambique Channel, to global scales of bringing knowledge and local-regional practice into decision-making circles. 2020 will be a critical year for ocean, biodiversity and climate targets in global conventions, and David is engaged in multiple processes (see expert groups) to bring coral reef science and learning into these global fora.

Kristen completed her PhD in coral reef ecology in the Coral Reef Ecosystems Laboratory at the University of Queensland in June 2018. During her PhD, she completed a series of studies and experiments that have improved our understanding of how seasonal, local (e.g., eutrophication), and global changes (e.g., ocean warming) influence benthic community structure with a focus on coral and macroalgal communities and their competitive interactions.
As a postdoctoral research fellow, Kristen has principally focused on exploring the relationships between oceanographic processes and coral reef ecosystem dynamics under present day and future conditions. This work has focused on using large scale flow-through mesocosms containing representative reef ecosystems (e.g., hard corals, macroalgae, fish, sediments) to explore the interactive effects of long-term exposure (18 months) to ocean warming and acidification. Using the Great Barrier Reef as a natural laboratory, she is also investigating the potential trade-offs (or compromises) made by so called “coral winners” following recent thermal stress events.
