Research Experience

My research is focused on nicotine and tobacco use disorder. Tobacco addiction overlaps with many problems, such as other substance use disorders, psychiatric disorders, and socioeconomic disparities. People affected by these problems continue to smoke at high rates while smoking rates among the general population have declined. I am excited about finding new ways to understand and fight tobacco addiction in order to help reduce smoking rates in these special populations. I use a variety of tools such as self-report questionnaires, ecological momentary assessment, computerized decision making paradigms, and functional magnetic resonance imaging (fMRI). Ongoing projects are investigating the stress-smoking relationship, in particular, how individual differences in distress tolerance and its neural correlates relate to the ability to quit smoking.
