Research interests

  • Use of contingency management to enhance abstinence and participation in substance use disorder continuing care
  • Early and brief interventions for substance use disorders, issues in mental health services delivery (e.g., wait lists, no shows/cancellations, patient flow)
  • Improving access to evidence based substance use disorder treatment through telehealth and individualized treatment approaches that are scaled intensity.

Current research

SBIRT implementation in medical subspecialty clinics – I am working collaboratively to examine factors predicting acceptance of a Brief Negotiated Intervention (BNI) after substance abuse screening as well as acceptance of formal treatment following BNI. This work is currently being conducted in a subspecialty HIV clinic and is an element of the current COSSAP grant.

Contingency Management – Despite its strong evidence base Contingency Management is grossly under-implemented in clinical practice settings. My focus is to identify ways to overcome implementation barriers while maximizing scientific fidelity.

Telehealth treatment modalities – Two recent grants (TeleMAT and COSSAP) have involve providing individual evidence-based addiction treatment via telehealth
