Noninvasive and localised drug delivery across the blood-brain barrier using ultrasound and microbubbles. I have over 12 journal publications on this topic and continue to develop different aspects of this technology. 

Existing collaborations relevant to drug delivery

I am currently working on three collaborative projects related to delivering drugs in the brain for paediatric brain cancer, glioblastoma multiforme, and Alzheimer’s disease.
