Research
I actively promote non medical prescribing and ophthalmic laser treatments delivered by optometrists.
I advocate high quality optometric education, expanding the care patients can expect from their eye care provider.

Teaching
I teach on the post graduate certificate in Independent Prescribing for Optometrists on both the one and two year programmes.
Independent Prescribing for Optometrists (PgCert) - Study - Cardiff University
I also teach on the post graduate module
