Dr James Guest is Reader in Coral Reef Ecology in the School of Natural and Environmental Sciences at Newcastle University. His research interests are diverse within coral reef science and include diseases, reproductive and larval ecology, recruitment dynamics, long term community change, bleaching and restoration ecology. He employs a range of techniques from large scale manipulative field ecology experiments to molecular biology methods including fluorescent in situ hybridisation and next generation sequencing of coral symbionts.
He has lived in five countries and worked with scientists from a range of disciplines in large international multi-disciplinary research groups. Between 2005 and 2008 he was employed by Newcastle University as part of an international European Union funded project involving a consortium of scientists from six countries to investigate reef restoration techniques on degraded reefs in the Philippines. He was appointed as a member of the Reef Restoration Working Group of the Coral Reef Targeted Research program of the World Bank-Global Environment Facility. An impact case study based on this work received a 4 star rating in the 2014 Research Excellence Framework. He was awarded a three year Lee Kuan Yew Postdoctoral Fellowship in 2009. Between 2012 and 2014 he held a senior research fellowship jointly with the University of New South Wales and Nanyang Technological University in Singapore to coordinate multidisciplinary research activities among a group of 17 marine ecologists and molecular biologists. During 2016 and 2017 he was a Powell Center Fellow at the University of Hawai'i's Institute of Marine Biology. From 2017 to 2022 he led a European Research Council Consolidator Grant at Newcastle University. He currently leads the Coralassist Lab at Newcastle University.
