Current projects

Antipsychotic polypharmacy and the prevalence, predictors, indicators and clinical outcomes with this relatively common prescribing practice that is not adequately supported by literature or clinical practice guidelines.

Smoking and schizophrenia research on the relationship between tobacco consumption and antipsychotic treatment, self-reported motivations for why persons living with schizophrenia smoke, and predictors of starting to smoke in first-episode patients.

The influence of serum lipids on clozapine’s clinical efficacy, including possible mechanism(s) that underlie previous work showing a positive correlation between serum triglycerides and clinical response to clozapine, and the metabolic effects of antipsychotics, including an investigation of the acute and chronic effects of the atypical antipsychotics on alterations in glucose and insulin parameters.
