I was born and brought up in London, but have Portuguese roots, hence the name. I went to Liverpool University in the 1980's where I took a BSc in Marine Biology and a PhD in Marine Ecology at the university's Port Erin Marine Laboratory on the Isle of Man. I then spent two years in Bolivia working on the artisanal fisheries of Lake Titicaca, before a one year contract in the Republic of Ireland setting up their fisheries acoustics programme. I came to Aberdeen in 1994 and was at the Marine Laboratory (now Marine Scotland Science) for over 16 years, working on fisheries surveys (acoustics and trawl) and, latterly, fish stock assessment. I took up my current position as MASTS reader in Fisheries Science at the University of Aberdeen in July 2011.
