SCIENCE TECHNOLOGY Professor of Environmental Health Department of Life Sciences Telext 868 662 2002 ext. 83740 E-mail PROF. DAVE D. CHADEE 104 Professor Dave Chadees contribution to public health research spans three decades. His research has had a significant impact on the control and management of vector borne diseases locally regionally and internationallyby merging two recognized medical disciplines epidemiology and medical entomologyparasitology to establish a hybrid area of specialization entomological epidemi- ology- a truly multi-disciplinary approach. This unique approach has expanded the range and depth of his research thereby allowing him to examine poorly studied areas of vector biology and to explore new frontiers in both the laboratory and the field. In recent years a third discipline has been added to his research specializationthe science of climate change. Professor Chadees work in the area of teaching and mentoring of postgraduate students is well recognized with the introduction of the Bioethics course the introduction of the Master of Public Health Programme in the Faculty of Medicine in collaboration with the University of AlabamaBirmingham and the introduction of the annual Research Day in the Department of Life Sciences Faculty of Science and Technology where he serves as the Research Day Programme Coordinator. His work has been widely recognized and he has been the recipient of numerous prestigious awards including the Wellcome Scholarship Gorgas Memorial Prize The Vice Chancellors Award for Research Excellence 2010 The Emmanuel C. Amoroso Gold Medal for Medical Sciences NIHERST 2013 and the Anthony Sabga Caribbean Award for Excellence in Science and Technology in 2013. Within the disciplines mentioned above his research covers a wide range of subjects and he has published over 250 peer- reviewed articles in international journals. He is the co-author of two books and he holds the record of having published in three of the four most prestigious or high impact journals in his field Science The Lancet and the New England Journal of Medicine - as well as other high impact journals. The impact of Prof Chadees research has changed the way vector control is conducted throughout the worldin particular by the introduction of new surveillance methods which have reduced manpower needs and the quantity of insecticides applied to the environment. This work has attracted the attention of numerous international organizations and he now serves as an expertadvisor to the World Health Organization the Pan Ameri- can Health Organization the International Atomic Energy Agency IAEA and as a lead author on the Inter-Governmental Panel on Climate Change. Professor Chadees experience in the control of dengue and chikungunya led to his work with the International Atomic Energy Agency in five Indian Ocean islands - Mauritius Reunion SeychellesMadagascarSri Lanka and Comoros from 2011 to 2014. This work involved training and implementation of laboratory studies preliminary to the eventual release of sterile insects SIT as a viable vector control method for dengue and chikungunya control. This project has now received funding for another two years and a new project has started in South East Asia and includes China Pakistan Sri Lanka Malaysia Thailand Indonesia Singapore and the Philippines. Previous work on SIT was recently published as a Supplement in the journal Acta Tropicaand he has served as a Co-editor and co-author of four scientific papers based on work conducted at The UWI St Augustine 2014. He also served as a lead author of the Health Wellbeing and Co-benefits chapter as a lead author for the Cross-Chapter Box on Livelihoods and Poverty as a lead author of the Technical Summary - Climate Change 2014 - ImpactsAdaptation and Vulnerability and as a contributing author on the Small Islands Chapter. All four contributions formed part of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Professor Chadees public service contribution involves his work on the LawGovernance and Ethics Committee and Scientific Advisory Committee of the South West Regional Health Authority Ministry of Health Trinidad. He is chairman of the Ethics Commit- teea role he has performed for the last three years.In additionhe was appointed a member of the Trinidad and Tobago Selection Panel for the Anthony N Sabga Caribbean Awards for Excellence in September 2013. Professor Chadees research has merged the science of climate change epidemiology and entomology and led to the develop- ment of the pre-seasonal Aedes aegypti treatment strategy. That is the treatment of mosquito breeding sites which contain eggs resistant to desiccation but which will hatch when the rains accumulate in containers. Therefore by treating these containers before the onset of the rainsthe newly hatched immatures will be killed thus reducing the mosquito population and preventing dengue transmission during the early part of the rainy season. Studies on the effects of different temperature regimens on the development of Aedes aegypti mosquitoes suggested that as the climate gets hotter the life cycle of these mosquitoes will be reduced and the intrinsic incubation period may also be shortened thus making Aedes aegypti more vector competent. In addition studies on the oviposition behaviour of Aedes aegypti not only identified circadian rhythms but also the factors
