Mark A. Freeman , BSc, PhD
Associate Professor of Aquaculture
Originally from England, Mark studied Marine Biology in Wales, specializing in zooplankton communities in Mauritius. After which, he was awarded a British Council scholarship to study larval shrimp in Mexico. He completed his PhD in Scotland, looking for natural pathogens of parasitic copepods (sea lice) causing epizootics on commercial salmon farms. A Royal Society of London Postdoctoral Fellowship, based at the University of Tokyo allowed a further four years study on parasites of farmed fish. He has been an Associate Professor at the University of Malaya, Kuala Lumpur, working with marine parasites and in marine biotechnology. He returned to Europe in 2014 to continue to work with colleagues at the University of Iceland in Reykjavík, before joining RUSVM in October 2015.

My main area of interest is aquatic parasitology, especially parasites infecting commercially important cultured and wild marine fish and shellfish that are considered to be important from a sustainable aquatic food security aspect and those with zoonotic / food safety concerns. Studies include the identification and characterization of novel / emerging and existing parasites in aquaculture facilities and the natural environment, using molecular, histological and EM techniques. This allows a better evaluation of pathogenicity to the host and enables the development of more sensitive diagnostic tools that can be used to implement improved management and control strategies therefore mitigating potential losses to farmed and wild stocks.
