Biography

Dr Cathy Montgomery is a Reader in Psychopharmacology at Liverpool John Moores University. Dr Montgomery’s PhD research investigated the effects of the recreational drugs ecstasy, cannabis and cocaine on working memory and the fractionated model of executive functioning. Since this time, her research has developed to investigate the effects of drugs on various aspects of cognitive function and their neurophysiological, neuroendocrine and neuroelectric effects. Since 2006 Cathy has been Honorary Secretary of the Psychobiology Section of the British Psychological Society which involves conference organisation and delegating for the Chair of the committee.

She is particularly interested in using neuroimaging techniques such as functional Near Infrared Spectroscopy and EEG to investigate brain indices of impaired cognitive function in drug users. Her work in this area has resulted in the supervision of a number of postgraduate research students.

The work of the substance use group attracts media interest. The ecstasy-related research has been reported in the National press in March and April 2005 (Daily Express, Daily Mail, Daily Telegraph, Independent) and in the Regional press in March 2005 (Belfast Telegraph, Liverpool Daily Post, Scottish Daily Express, Western Morning News, Yorkshire Post). International news agencies have also reported aspects of our work (Reuters, March 2005).

The group was also represented by Dr Montgomery on Channel 4’s much publicised Drugs Live: The Ecstasy Trial (September 2012), and we have ongoing relationships with local television (BBC Look North, BBC North West News; 2012, 2013, 2014), Granada reports (2015).
