Helen Limbrick gained her BSc (Hons) Psychology degree and PhD from Northumbria University. During her psychology degree Helen researched the relationship between prenatal testosterone and mathematical skills in six to eight-year-olds. Helen built upon this research during her PhD where she explored a potential link between the 2D:4D ratio (a proxy marker for prenatal testosterone) and performance on basic numerical tasks in adults and children. After an initial stint of teaching at Northumbria University during her PhD, she became a lecturer at Teesside University in early 2008. Helen is module leader for the Introduction to Core Areas in Psychology which covers cognitive, social, developmental and biological psychology, and individual differences. She also teaches on the module Social and Biological Psychology.
