Lloyd completed BSc Honours at the University of the Western Cape. His project dealt with the production of monoclonal antibodies against the female specific hormone, vitellogenin, in the freshwater crab for the purposes of using the crab as a bioindicator for the presence of endocrine stimulating hormones within freshwater reserves.
He furthered his studies by completing his Masters in Medical Biosciences, in which his thesis investigated potential cytokine profiles of macrophages exposed to various concentrations of amine-functionalised carbon nanoparticles.
During his Masters, Lloyd worked at the City of Cape Town in their Scientific Services Branch where he contributed to the development and validation of water quality testing methods for drinking and non-drinking water supplies. He continued on to work at UCT in the Division of Immunology and, subsequently, Stellenbosch University in Molecular Biology and Human Genetics under the MELABO Project investigating adverse birth outcomes linked to HIV status.
