Research Interests
The long-term goal of my research is to help make addiction treatments more effective and available for more people. My hope is that by clarifying what addiction is, how drugs of abuse change us, and how current treatments work that we’ll be able to offer better care to our patients.

My recent work has been motivated by three questions:
1. How does our response to stress make us vulnerable and/or protect us from becoming addicted to drugs of abuse?
2. How do drugs of abuse change our thoughts, feelings, and behaviors in ways that make unhealthy and risky behaviors – like continued drug use – more likely?
3. How, and for whom, do treatments for addiction work?

The methods I use are multidisciplinary, but draw primarily from recent developments in psychology, neuroscience, and statistics. I focus on the psychological processes (e.g., emotion, perception, decision-making, etc.) that are affected by drug use and abuse and I use a combination of behavioral, self-report, and physiological (e.g., EEG, EMG, etc.) methods to measure them. A portion of my research is aimed at refining how we quantify these measurements and the methods we use to analyze them.
