Pablo Romero

MAAC Lab Research Associate

I completed both my BSc. in Psychology and Master in Clinical and Health Psychology at the University of Malaga (Spain). After that, I got my Doctorate in Clinical Psychology Hospital of Jaen (Spain), and my Ph.D. also at the University of Malaga (with distinction and European mention). Finally, I got a Master in Neurosciences at the University of Cadiz (Spain). I have more than 10 years of clinical experience with patients with addictions, mood, anxiety and psychotic disorders in both Spanish Public Health Services and my own private practice in both group and individual formats. My research interests go from cognitive-behavioural processes involved in psychological disorders from both transdiagnostic and disorder-specific approaches, to the interplay of biological and psychological variables in the development, maintenance and treatment of mental disorders, but also the implementation of Internet-based psychological therapies.

I’m a fourth year Bachelor of science student at Dalhousie, majoring in Psychology. My interest in substance use and personality started when I got an opportunity to work in the MAAC lab as a research assistant over the summer. This led me to pursuing my honours degree focusing on exploring personality characteristics (anxiety and self-esteem) of first year university students with a history of reading difficulties under the supervision of Dr. Sherry Stewart and Dr. Hélène Deacon. With this research I hope to spread awareness on the susceptibility of this high risk population to personality and substance use problems. Following graduation, I hope to pursue my PhD in Clinical psychology where I can help people and spread awareness of mental health problems through research.

Further, I studied the academic abilities of university students with undiagnosed reading difficulties. Now, for my second comprehensive project for which I will be working with Dr. Stewart, I am continuing to study the academic abilities of university students with undiagnosed reading difficulties, but incorporating information about personality traits and substance use to determine how these factors influence the academic success of this population. I am greatly looking forward to broadening our understanding of this population’s academic abilities and the factors that influence said abilities, as well as for the opportunity to work with Dr. Stewart!
