Reproductive geneticist and researcher
Patricia Anastastia Martin DeLeon (born 13 July 1944) is a Jamaican reproductive geneticist who is specialists in the male reproductive system. She is the Trustees Distinguished Professor of Biological Sciences at the University of Delaware. In 2010 she was awarded the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring by Barack Obama.
Early life and education.
DeLeon was born in Port Maria. She was one of nine children, and had to lobby the principal of her high school, Excelsior High School, to waive the fees to allow her family to attend. She became interested in botany as a child and learnt the Latin names of all the plants that she collected. The principal agreed based on DeLeon's academic performance. She attended the University of the West Indies for her undergraduate studies, where she focussed on zoology and chemistry. After earning her undergraduate degree DeLeon moved to Canada, where she joined the University of Western Ontario for her doctoral degree in microscopic anatomy. She was subsequently a postdoc at McGill University.
Research and career.
In 1976 DeLeon joined the faculty at the University of Delaware. 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. The over-expression of SPAM1 can give rise to cancer. In 2009 she was named the Trustees Distinguished Professor of Biological Sciences. 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. She is working on non-invasive diagnostic methods to identify embryos that are most likely to result in successful IVF. 
Throughout her career DeLeon has worked to support undergraduates gain research experience.
