I graduated with a Bachelor's degree in Mathematics and Physics in 1993 and have since been teaching at secondary level in Malta. In 2010, I was appointed Mathematics Head of Department and served in this role for seven years. In 2011, I successfully completed a Master's degree in Mathematics Education carried out with the University of Malta. In 2013, I started my doctoral journey embarking on a research project that involved the design and implementation of a 14-month CPD programme for secondary school teachers of mathematics. The research, entitled "Learning to Teach Mathematics through Inquiry: A Case Study of Continuing Professional Development in Malta" was carried out with the University of Nottingham (UK) and completed in 2018 under the supervision of Professor Malcolm Swan, Professor Jeremy Hodgen and Dr Colin Foster. I presented my research on mathematics education, lesson study and teacher professional learning in a number of conferences, both locally and abroad.
