I joined UCL Institute of Education in 2005. I'm an Associate Professor, based in the Centre for Inclusive Education. 

Between 2011 and 2017, I led a landmark research study of the everyday educational experiences of pupils with an EHCP/Statement, which included the UK’s largest observational study of pupils with SEN. 

I'm a leading expert on teaching assistants. I was a researcher on the world's largest study of TA deployment and impact: the ground-breaking DISS project. From this work, I created the award-winning Maximising the Impact of Teaching Assistants (MITA) programme. I'm currently editing the first collection of international writing on TAs.

I'm a co-investigator or consultant on several SEN-related projects, including Researching Allied health In Schools and Education (RAISE) and Road Safety and Me. I also sit on the lead group of the SEN Policy Research Forum. 

A passionate advocate for the power of educational research, I write about applying evidence in schools and classrooms, and I present the IOE's Research for the Real World podcast.

I have a PhD in Education from the University of Reading, and an MA in Social Policy from Oxford Brookes University.
