Hailing from Trinidad and Tobago, Joel graduated cum laude from Harvard College (Cabot House ’20) with an SB in Engineering Science. During his time there, he conducted research in the laboratory of Prof. Samir Mitragotri under the supervision of Dr. Eden Tanner, culminating his his senior thesis investigating the use of ionic liquids for transdermal delivery of hydrocortisone-loaded nanoparticles for sustained atopic dermatitis treatment.

Joel joined BUBBL in October 2020 as a DPhil student, working under the joint supervision of Profs. Robert Carlisle and Constantin Coussios. He aims to optimize the combination effect of solvents and cavitation nuclei in ultrasound-assisted transdermal delivery of vaccines. His program is funded by the All Souls Hugh Springer Memorial Fellowship, and he is a member of St. Edmund Hall.

Joel’s research focuses primarily on drug delivery applications, especially non-invasive transdermal delivery. His investigations have covered a broad range of technologies – from nanoparticle fabrication for tuned drug release to the use of unique solvents like ionic liquids to facilitate delivery to the skin.

His DPhil at Oxford centers on fabricating biodegradable sonosensitive cavitation nuclei (PCaNs) that can be exposed to low-intensity focused ultrasound to facilitate transdermal drug and vaccine delivery. His project aims to provide a compelling vaccine administration alternative to needle-based injections for vaccinations, through the pain-free, quick, and non-invasive means of cavitation-induced delivery. Woefully inadequate supplies of vaccines have proven to be a problem in dealing with global health crises, and thus a novel method that can deliver the vaccine to an immune responsive organ like the skin can help to address such a crisis more quickly in the future.
