My research takes an interdisciplinary approach to understanding substance use among individuals with medical and psychiatric comorbidities. Most recently, this work has focused on three areas: (1) the mechanisms and outcomes of tobacco use among people with HIV (PWH); (2) digital interventions for smoking cessation among individuals with serious mental illness; and (3) the intersection of cannabis and opioid use for symptom management.
My work in tobacco use and HIV evaluates the mechanisms and outcomes of tobacco use among PWH, a population with disproportionately high smoking rates. Coupled with the widespread use of antiretroviral therapy, PWH actually lose more life years to tobacco use than to HIV. My research projects seek to understand: (1) the mechanisms that underlie high smoking rates; (2) why existing treatments are less effective and relapse rates are higher among PWH; and (3) how HIV and smoking may act synergistically and ultimately lead to worse clinical outcomes including cancer and impaired immune function.
I am also collaborating with investigators at Duke University on a multi-site clinical trial to evaluate the effectiveness of a mobile health application (i.e., smartphone app) for smoking cessation among individuals with serious mental illness. We are collaborating with outpatient psychiatry clinics at Erie County Medical Center on this trial.
We also recently began a study to better understand cannabis use in the context of cancer. Specifically, we are studying whether cannabis may help to reduce opioid use for managing pain among cancer patients. This study is a collaboration with Roswell Park Cancer Institute, the University of Pennsylvania and Sidney Kimmel Cancer Center.
