Merideth Addicott, Ph.D.

Merideth Addicott

Merideth Addicott, Ph.D., joined the Center for Addiction Research’s research faculty in 2017. Her background is in studying how psychoactive drugs affect people’s mood, behavior, and decision making. She has studies the short-, and long-term effects of alcohol, caffeine, nicotine, methylphenidate, and opioids.

Addicott’s current 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. She is excited about finding new ways to understand and fight tobacco addiction in order to help reduce smoking rates in these special populations. Addicott uses a variety of tools such as self-report questionnaires, ecological momentary assessment, computerized decision making tasks, and functional magnetic resonance imaging (fMRI).

Ongoing projects are investigating:

  • How individual differences in distress tolerance and its neural correlates relate to the ability to quit smoking.
  • New medications that may affect individuals’ tobacco use
  • How individual differences in electronic-cigarette use can be best measured
