Professor Fitzgerald has a substantive interest in the development of new technological tools to help in the diagnosis and management of mental health conditions. He has received support from, and consulted with, several existing medical device companies: mostly smaller companies working on the development of new brain stimulation related tools.
In addition, he is a founder of Resonance Therapeutics (RTx). RTx aims to develop a highly novel closed loop transcranial alternating current stimulation device for use in the treatment of depression and other disorders.
