Una M. Ryan

Una M. Ryan (born 1966) is a biochemist from Ireland, researching parasites and infectious agents in Australia, where she lives. She is an associate professor at the School of Veterinary and Biomedical Sciences of Murdoch University. In 2000, she received the Frank Fenner Prize for Life Scientist of the Year from the Prime Minister of Australia for her work in isolating a method of diagnosing parasites.

Una Ryan was born in Ireland in 1966 and completed her undergraduate work in zoology at University College Dublin in 1988. The following year, she moved to Australia and began working at Murdoch University. Ryan continued her studies earning her PhD in 1996 in parasitology, with a specialisation in on protozoan parasites. Her research has analysed the transmission and epidemiology of infectious disease parasites, initially focused on Cryptosporidium, a protozoan parasite which causes diarrhoea and in severe cases can result in death. Cryptosporidium and Giardia are the two most prevalent parasites causing public health risk from water utilities in developed nations, due to contamination of water catchment areas by livestock. Ryan developed a test to verify if the parasites are present in water samples and if they are present, whether they are one of the two types that are harmful to humans. She filed a worldwide patent on her DNA method of diagnosing Cryptosporidium and was awarded a Frank Fenner Prize for Life Scientist of the Year, one of the Minister's Prizes and highest award given by the Prime Minister of Australia to recognise scientists' contributions.
