Research
Dr. Jeremy Brown is an engineering physicist with a strong track record of successful innovation. He has worked extensively in the field of hearing, developing implantable sub-cutaneous piezoelectric bone conduction hearing aids, and ultrasonic and fibre-optic diagnostic imaging probes for the ear, among other novel technologies. He holds two patents, with three more pending, and is a director of a spin-off company commercializing the new technologies.
In 2017, Dr. Brown and his colleagues, including Drs. Robert Adamson, James Fawcett, John Frampton and Adrienne Weeks, received $2.68 million from ACOA's Atlantic Innovation Fund (AIF) and matching partners, for a new project to develop a miniature ablation endoscope for guided neurosurgery. Among other grants, Dr. Brown has received:
- AIF funding in the amount of $2.9 million to develop new clinical tools using high-frequency ultrasound and optical coherence tomography
- NSERC and Nova Scotia Health Research Foundation funding to advance his efforts to fabricate high-frequency piezoelectric micro-composites for use in auditory technologies
- NSERC, Nova Scotia Health Authority Research Fund, Springboard Atlantic and InNOVAcorp funding to develop a variable-sampling beamformer for high-resolution ultrasound endoscopy
Academic background
Jeremy Brown received a BSc in engineering physics from Queen's University in Kingston, Ontario in 2001. He stayed on at Queen's to complete his PhD and a post-doctoral fellowship in applied physics. In 2006, he honed in on his biophysics focus, with two years of post-doc training in medical biophysics at Sunnybrook Research Institute in Toronto. Upon completion of this training, he re-located to Halifax, Nova Scotia, accepting a position as assistant profession in the School of Biomedical Engineering at Dalhousie University. He received the school's teaching award in 2010, and an innovation award from the Halifax Discovery Centre in 2013.
