She attended the University of the West Indies for her undergraduate studies, where she focussed on zoology and chemistry.
[3] DeLeon has extensively studied the Sperm adhesion molecule 1 (SPAM1), a glycosylphosphatidylinositol linked membrane protein.
The mechanisms that underpin the expression of these proteins are poorly understood, but are crucial for the development of assisted reproductive technology.
[5] Alongside her work on male fertility, DeLeon has studied particles in the fallopian tube, the understanding of which may improve the outcomes of in vitro fertilisation.
[2] She is working on non-invasive diagnostic methods to identify embryos that are most likely to result in successful IVF.
