Research Interests

I've spent my research career investigating the phenomenology and the successful treatment of depression. Much of my recent clinical research in this area has been informed by the rich conceptual and methodological framework provided by the multidisciplinary domain of cognitive neuroscience, which provides a useful meta-theoretical vantage point from which to integrate discoveries across traditional disciplinary boundaries (Ilardi & Feldman, 2001; Ilardi, 2002). Such integration is especially important, I believe, because depression research now encompasses several largely distinct research literatures that span multiple levels of analysis: molecular, genetic, neurological, cognitive, affective, social, behavioral, etc.

Over the past four years I have collaborated extensively with neuroscientist Ruthann Atchley to investigate maladaptive cognitive processes (e.g., attention, self-representation, semantic processing, etc.) in depression. The collaboration brings together her expertise in neuroimaging and neurocognitive assessment with my own clinical expertise regarding the cognitive phenomenology and treatment of depression. By pioneering the use of divided visual field techniques to isolate the functioning of each cerebral hemisphere, we have made promising discoveries regarding the enduring nature of negativistic, maladaptive depressive representations in the brain's right hemisphere - discoveries with considerable potential clinical applicability. Moreover, we have utilized electroencephalographic (EEG) techniques to develop a method of investigating depressive self-representation (e.g., "I am a loser") in a fashion that completely obviates the need for self-report, relying instead on real-time analysis of EEG brainwave patterns as the individual reads a series of self-referent sentences.

Another recent project involves the development of a novel therapeutic treatment for depression that focuses upon numerous modifiable lifestyle factors - e.g., aerobic exercise, omega-3 essential fatty acid supplementation, light exposure, sleep hygiene, social intimacy, behavioral activation, and anti-rumination techniques - that have each independently been demonstrated to have antidepressant properties. Moreover, the increasingly sedentary, isolated, and fast pace of modern life appears designed to thwart, rather than to facilitate, the cultivation of each of these factors - a fact which may help explain the relentlessly increasing prevalence of depression in the developed world over the past several decades.
