She is an expert in substance use research and has more than 130 publications in this area. In particular, her research focuses on understanding cigarette, e-cigarette, and other tobacco use among youth and adults to identify strategies to reduce tobacco use and tobacco-related harm through treatment and policy. She currently leads several innovative projects including studies evaluating the use of mobile technology and wearable biosensors to deliver treatment and randomized clinical trials studying the effects of potential tobacco regulatory policies. Her research has had high impact, including being cited in the US Surgeon General’s 2016 Report, and in the US FDA’s 2022 proposed tobacco policy providing scientific support for banning menthol flavor in cigarettes. Furthermore, she provides specialty clinical care at Smilow Tobacco Treatment Service in Yale New Haven Hospital treating patients who use tobacco products. Given her additional expertise in youth tobacco use, she supported the expansion of the outpatient hospital services to address the increasing need to provide treatment for youth using e-cigarettes who need help quitting. She has been elected to multiple leadership roles as an expert in tobacco use, including as the Chair of the Tobacco Regulatory Science international working group advising on menthol tobacco product standards and the Advisory Committee of the Treatment Research Network for the international Society for Research on Nicotine and Tobacco.
