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 and teacher professional learning in a number of conferences, both locally and abroad.

Involved in the "Supporting Mathematics and Science Teachers in addressing Diversity and promoting fundamental Values" (MaSDiV) - a ERASMUS+ Key Action 3 project. This project involves the design, implementation and evaluation of a continuing professional development project for teachers of mathematics and science. I am one of the leading members of the University Project team at the Faculty of Education.
Leader of the Schools for Access to Learning, Inclusion and Equity Networking Together (SALIENT2) - a Faculty of Education outreach project that aims towards supporting primary state and non-state schools in developing communities to sustain teacher professional learning and development.
A member of the organising committee of the 6th International Symposium on New Issues in Teacher Education (ISNITE 2019) held at the Valletta Campus, University of Malta, 16-18 September 2019.
Initiator, designer and leader of Lesson Study in Malta through the "Collaborative Lesson Study Malta" (CLeStuM) project. CLeStuM is inspired by the theme of ‘Teachers Learning Together’. For the scope of sharing the work of teachers in schools, disseminate and cultivate this approach to teachers continuing professional development, the CLeStuM website was launched in December 2019 (see www.clestum.eu).
There are also two other websites that I designed for teachers' professional learning:
The 'Invest in Math Sense' website - https://investinmathsense.wordpress.com
The 'Teaching Mathematics through Inquiry' website - http://iblmaths.com
Coordinator of the following programmes of study:
1. Master of Arts in Educational Leadership and Management
2. Postgraduate Certificate in Developing the Educator
3. Community of Professional Educators (CoPE) courses offered to schools by the Faculty of Education
