Laura Charlotte Hewitson[2] is a British-born primate researcher noted for her work in the fields of reproductive biology and behavior. She is an Affiliate Scientist at the Washington National Primate Research Center in Seattle, WA.[3] Additionally, she is Research Director of Johnson Center for Child Health and Development in Austin, TX.[3] From 2002 to 2010 she was an Associate Professor of Obstetrics, Gynecology and Reproductive Sciences at the University of Pittsburgh School of Medicine[3] and member of Magee-Women's Research Institute and Foundation (MWRI&F) in Pittsburgh, PA.[3]

Research

Hewitson's research has primarily focused on embryo metabolism, cytoskeletal dynamics, centrosome abnormalities during fertilization, assisted reproductive technology (ART) in non-human primates and infant primate neonatal development.[citation needed] More recently, Hewitson’s research has focused on understanding genetic and environmental influences that lead to adverse pregnancy outcomes, with special emphasis on autism spectrum disorders (ASD). Her research has been funded through the National Institutes of Health,[4] as well as private foundations.[5] Hewitson’s work has been published in many journals, such as Science, Nature Medicine, Biology of Reproduction, Human Reproduction, Fertility and Sterility, Acta Neurobiologiae Experimentalis, Journal of Toxicology and Environmental Health, and the Journal of Law, Medicine and Ethics.

Hewitson’s work on primate fertilization examined the role of the centrosome during assisted reproduction and identified unique check-points during the first cell cycle. She also explored the safety of new methods of assisted reproduction by producing infant primates by ART to follow their early development and behavior (see Selected Publications).

Hewitson’s more recent research has focused on the study of genetic versus epigenetic (environmental) causes of neurodevelopmental disorders.[6] She is now continuing this research in Austin, TX as the Research Director of Johnson Center for Child Health and Development.[3]
