Pat Marks was one of Australia's leading entomologists and malaria experts. She worked for the Mosquito Control Committee from its inception in 1943 until its closure in 1973. Marks was then transferred to the Queensland Institute of Medical Research as Principal Entomologist. She described thirty-eight new mosquito species and authored well over one hundred publications. She retired in 1983, but continued with her taxonomic research there for some time. Pat Marks was a one-time President of the Royal Society of Queensland, the Entomological Society of Queensland and the Australian Entomological Society, as well as a Life Member of the Mosquito Association of Australia. She was nicknamed Pat or Patricia after being christened at St. Patrick's Cathedral, in Dublin and this was the name most often used by herself and her family.
