Dr Joe Valentine

Senior Scientist

 

B.Sc. (Marine Biology) University of Tasmania 1995;

B. Sc. (First Class Hons.) Marine, Freshwater and Antarctic Biology, University of Tasmania 1996;

Ph.D. (Marine Ecology) University of Tasmania 2003

 

Joe is an experienced marine scientist with a broad range of expertise in relation to management of invasive marine species and marine environmental management. His Honours project involved testing a range of options for ballast water treatment to prevent the introduction and spread of toxic dinoflagellates. During this investigation, mild heat treatment was identified as a practical and cost-effective method of inactivating dinoflagellate cysts.

 

Joe’s PhD research examined the ecology of the introduced Asian kelp Undaria pinnatifida in Tasmanian waters. During the course of his research, Joe developed skills in the areas of benthic ecology, experimental design and analysis, marine taxonomy and field sampling operations.

 

Joe has worked on a diverse range of marine pest projects related to the National System for the Prevention and Management of Marine Pest Incursions, including the ‘Draft National Control Plans for Agreed Pests of Concern’ and the ‘Review of the Marine Pest Monitoring Guidelines and Manual’ Joe has also conducted biofouling risk assessments and coordinated in-water and dry-dock vessel inspections.
