Dr. Marco-Dean Brown is a Jamaican zoologist and parasitologist whose research focuses on the intersection of human health, animal health and the environment through a One Health approach. He was awarded a Doctor of Philosophy (PhD) in Zoology, specialising in Parasitology, by The University of the West Indies (UWI), Mona, in 2026, having previously completed a Bachelor of Science degree in Experimental Biology at the institution in 2015.
His doctoral research examined the molecular epidemiology of Angiostrongylus cantonensis, commonly known as the rat lungworm, in Jamaica, providing significant new insights into the parasite’s transmission pathways, host species and environmental influences. His research identified 13 previously unrecognised species capable of carrying the parasite, with eight of these findings representing global first records, expanding scientific understanding of zoonotic disease transmission in Jamaica.
Beyond his doctoral research, Dr. Brown has contributed to work in parasitology, invasive species, biodiversity and environmental health. He is passionate about translating scientific discoveries into practical solutions, strengthening research capacity and advancing evidence-based approaches to public health and environmental management in Jamaica and the wider Caribbean.
