Dr Niamh O’ Meara is a lecturer in mathematics education and deputy director of EPISTEM, the National Centre for STEM Education in Ireland. Niamh completed her PhD in 2011, under the supervision of Prof. John O’Donoghue and Dr Olivia Fitzmaurice. As part of this thesis she investigated the knowledge required to teach mathematics at second level. She continues to research this issue of teacher knowledge today whilst her other research interests include curricular issues in mathematics education, improving attitudes and performance in mathematics and numeracy education. She is currently engaged in a number of research projects in these areas with colleagues from Ireland, Australia, Holland and Spain, and is the project lead for Career Mathways, an online suite of teaching and learning resources promoting careers in STEM.
