Dr Sarah J H Lalor

Senior Lecturer

Faculty:Faculty of Science and Engineering

School:Vision and Hearing Sciences

Location: Cambridge

Areas of Expertise: Health, social care and medical innovation

Sarah joined the Department of Vision and Hearing Sciences in 2012. She completed both her undergraduate studies and her PhD at Anglia Ruskin. Sarah’s main research interest is improving the detection of abnormal vision development in children using non-standard images.

Profile on Research Gate


During her undergraduate studies, Sarah won a Nuffield Undergraduate Research Bursary to do a summer research project entitled Binocular summation for images defined by luminance or contrast within Anglia Vision Research.  The project was undertaken under the supervision of Dr Sarah J Waugh and the results were presented at an international conference (VSS) in America in July 2009.

After her undergraduate studies, Sarah was awarded a University Graduate Teaching Assistantship scholarship to undertake her doctoral studies into how a more sensitive test for amblyopia could be designed, under the supervision of Dr Sarah J Waugh, Dr Monika A Formankiewicz and Prof John Siderov. 

In the second year of her PhD, Sarah won first prize for a talk given at our Sixth Annual Student Research Conference. Her main research interest is the development of more sensitive tools using non-standard images for improving detection of amblyopia in children.
