John O'Toole

Biography

John M. O' Toole received the B.E. (1997) and M.Eng.Sc. (2000) degrees from the University College Dublin, Ireland, and the Ph.D. (2009) degree from the University of Queensland, Australia. His Ph.D. thesis received the Dean's award for outstanding research in 2010. Prior to Ph.D. study, he worked in industry (2001-2003) as a consultant engineer in control systems and as a research assistant (2003-2005) at the Signal Processing Research Centre in the Queensland University of Technology, Australia.

His postdoctoral research has included topics in signal processing and biomedical applications at the Centre for Clinical Research (2008-2010), University of Queensland, Australia; DeustoTech-eLIFE Group (2011-2013), University of Deusto, Spain; and from 2013 on at the Neonatal Brain Research Group, now part of INFANT, at University College Cork, Ireland.

Research interests include time-frequency signal analysis, discrete-time signal processing, efficient algorithm design, and biomedical signal analysis. Papers and computer code can be found at http://otoolej.github.io/.
