Research Interests: 

I am a third-year graduate student in the Impulsivity Neuroscience Lab. Broadly, my research interest is in neurocognitive mechanisms underlying impulsivity and risk-taking behaviors (e.g., substance use). My specific research interest is to examine the relationship betwen positive urgency (i.e., a tendency to act rashly under extreme positive emotions) and alcohol-related risk-taking while incorporating behavioral experimental and neuroscientific methods. To this end, I am currently developing a novel positive emotion induction method that overcomes previous methodological limitations. Positive emotions are integral for positive urgecy to operate. However, limitations in existing positive emotion induction methods hinder the progress in positive urgency research because: 1) existing positive emotion induction methods induce low arousal (e.g., calm) rather than high arousal positive emotion (e.g., excitement) that are more likely to increase risk-taking; and 2) most positive emotion inductions are passive and fail to use more powerful, ecologically valid, personally relevant emotional stimuli.

My master's thesis examined neural correlates of negative urgency (i.e., a tendency to act rashly under extreme negative emotions) between tobacco users and non-tobacco users using resting-state fMRI data. 

In addition to research in Dr. Cyders' lab, I am also involved in longitudinal imaging data analysis from three early psychosis pharmacological intervention trials funded by NIH and other private research organizations through Dr. Alan Breier's lab at Indiana University School of Medicine.
